- In this video I'm making a NVR (No Volt Release) controlled power strip / 4 gang for my assembly bench in the workshop. This is designed so I can fit it to any workbench and it gives me 4 outlets / sockets all protected by a single NVR. I'll explaining what an NVR does, why you need them in your workshop and why there's more to them than just a big red 'stop' button! Enjoy!

A good workshop saftey tip, and a very good demonstration of what not to do with your router table. "Takes ages to clean up... he's got no hands" 😂
By popular request I'll be doing the grand tour of my router table v2.0 very soon! 👍😃
Perfect - just what I was looking for. My next little project!
Cheers
Andrew
That tape trick!!!!!!!! Life changed.
Thank you. This is definitely very good extra safety option and I just accidentally found this video and i am wondering why l never thought in 40 years about it. This cost nothing to peanuts to implement but gives that peace of mind for once ( well... many) in life coincidence of human error or negligence. Thank you!
Just found your channel and binge watching. You are right of course, by the end of Easter my router table will get an NVR. Thanks for the timely kick up the behind!
Cheers and welcome to the channel! 👍
Though this video describes using an NVR for safety purposes, I came here looking for a way to protect sensitive and expensive electronics when power is restored after a power outage. This might do the trick. Thanks for the demonstration.
Cheers mate, this has to be the best video ANYONE ever watches, I'm 65, and try to keep safe and this kinda helpd me make a better job of keeping my fingers on my hand instead of the floor.big thanks mate //..... from Garry at barnsley
Cheers Garry! 👍🛠
The compressor part made me chuckle. Very cool video.
Never herd of nvr but now I been giving good advice
Thanks
I added these to the start of my socket loop so I can turn off all socket but to be honest I didnt know they turn off I guess like a trip switch if you lose power great video
Nice job and spot on with the importance of using the NVR switch/button 👍👍👍
Cheers Nick! 👍🛠
Doing the specs for a new workshop just now and, having seen this, am adding NVR's to the power strips. Besides the safety aspect it'll look class. Cheers!
Glad you found it useful! 👍🛠
My switch arrived and being a 4 pin type I connected both live wires to one side pair of contacts and the two neutrals to the other side pair. Both earth wires joined on a screw in the bottom of the casing. All works as it should. I made mine as a portable extension so I can take it where ever I need it. Thanks.
What a great video, picked up some tips and I'll be making one of these very soon. Thank you.
Great advice. When I build my workbench I'll be sure to include a NVR.
Great idea. Something else that is very useful is a foot switch. I made an extension cord with a foot switch in it and use it mostly on my drill press. So useful when you need to use 2 hands on the tool.
Great idea, going to order an NVR switch later for my model making workshop.
👍🛠
Good thinking, have power cuts from storms here in Aus regularly, though my router table has an NVR switch built in as well as most of big equipment, I will still add this to where I use power boards because you just never know.
Very nice description mate. Thank you very much
I'm poor in spark (electricity) - the part in this video that I wanted most to see, u made it fast which is the cables connections, where goes blue, where goes green... But yah, great video. Well done
Me too!
That's what spoiled for me, carried out all the work,and cannot get it to go, due to no information as to the connections
brilliant project, really liked the technique to transfer hole template to the board (using tape), great channel :>)
Cheers for watching and welcome to the channel! 👍🛠
smart, actually!
Looks a great channel, we need more Brits doing great stuff like you (and Peter Millard who I spotted your comments on).
Cheers Simon! Yes, us Brits are thin on the ground on CZcams! 😃🛠
I like this especially for safet in the shop. I will be making one. Very nice!
Great video as usual. NVR's next on the list!
Cheers Jim! 👍
Just reran your very useful video . Love the work thanks.
I know it's not as neat but I use in-line non-latching (active) RCDs. They give you the NVR functionality and the protection against electric shock (I'm old enough to remember the tragic case of Lizzie McMullen).
Great one mate. Defford going to do that in my workshop.
No worries! 👍
Great idea. My table saw and router table have these fitted but I have power strip and some (black) cable (sorry) so I will be making this rig up Thank you. Just have to wait for the switch now.
Great video, thanks Andy. If you have any trouble with the 4 gang riding up and off its screws when you pull plugs out, a simple strip screwed across the top would keep it in place. I've even consider butchering Aldi's router table for its NVR switch as they often reduce the table down to £15 when they need the space for the next influx of Workzone kit.
Good tip! No probs with it coming off so far - might be a later addition. 👍
I like the NVR switch idea. I’m an journeyman electrician in US and found it odd that you put all your electrical connections in a wood box. Is that common in the UK? The reason I bring this up is that the most common place for an electrical system to fail is at the connections. When you have an electrical event you create heat and flame that can set the wood on fire. In the US all electrical connections above 60 VDC and 30 VAC are required to be in a listed junction box. Usually a plastic or metal box designed to handle the heat and flames.
"Have some bait".... ha ha, memories of working with a load of North East lads down the pit in Nottinghamshire..
Nice Videos marra
Cheers
Paul
Pit in Nottinghamshire? They could literally have brought coals to Newcastle! 😃🛠
Very nice! I never used an NVR switch, but over the years I made a few similar outlet strips that used a toggle switch as the master on/off strip between a pair of retail power strips so I could turn off all power to the workbench where those power strips were mounted. That was years ago, long before the "safety nazi's" stuck their heads into the scene. I also made one that used commercial WireMold surface mounted wiring races (1/2" / 12.5mm thick x 1" / 25mm high and pretty pricey, but limited space offset cost) which had an A-C outlet every 6 inches; mount the back plate to whatever (wall of bench) and snap the front part with the wiring and outlets onto the back plate and connect the power source. I mounted toggle switch box (aluminum hobby box) at one end, which I made for an electronics workbench for the attached shelf 18" above the bench top using 90 degree angle brackets and the bottom of the shelf a few inches from the back of the bench facing the front. Easy access to plug-in soldering irons and other, along with the shop sound system; one switch and everything got turned off at once when I was done for the night.
Suggestion: Your switch box sticks out too far from the workbench top. I realize that the NVR switch needed room for the wiring, but I would have routed out a recess in the mounting board for the wires so that the wiring went into the mounting board to use that ~ 25mm and the switch would have been almost flush with bench top with it recessed into the mounting board. The 3-wire cables could go out the side of the "box" & mounting board into grooves cut with a router.
Great stuff! Wanted it to be as easy to 'hit' as possible when the router table is set-up. The downside is that when it's not set-up it's still just as easy to hit. 😂👍
Great idea!!!
Cheers Jim! 👍🛠
Thanks for Very helpful tip
Thank you , it is perfect
Love this idea Andy, attaching a 4 gang to an NVR. Similar applies to going on holiday, don't take 4 adaptors... take 1 adaptor and a 4 gang! I find that those keyhole hooks for 4 gangs can be a bit shit, but one tip i've picked up is to use some of that galvanised banding to strap them down to whatever its being mounted too. Really quick and secure solution. Can even get black plastic coated banding from Amazon if you want it to look nice.
Yup - I do that too. One adapter and a 4-gang... plus a couple of spare adapters 'cause I'm always para I've brought the wrong ones. 😂
Ffs. Anyone want to buy 3 euro adapters....goin cheap
@@JuiceBanger1 lmao :D Happy to help!
Ditto the tape trick, I had never seen that before.
Always unplug equipment or lock out when changing blades or bits!
Here in the U.S. they are called magnetic starters, and not required on new shop tools only on large industrial tooling. I do like them and should be required.
In the final setup of my shop (2 car garage) is done all of the power tools will be on a single mag starter will E-stops around the shop.
Great stuff - never heard of magnetic starters too so cheers for the info! 👍
Nice job. I prefer the switches that you have to pull them out to start it and then push it in to make it stop. Just ease of use.
👍
LMFAO!!! Got my sub when you demonstrate adjusting the router bit with you tongue!! I'm in, dude. Freakin' hilarious. PLUS, good explanation. Lot's of legit injuries in shops that way, eh?
Thanks for the video. I hadn't thought of the NVR use for hand power tools, will modify my workshop supply for sure. I have a query. My NVR has 5 terminals, 2 IN, 2 OUT and I understood the 5th is for the supply to the 'latching/NVR' contactor in the switch. Am I mistaken because I didn't see you connect a 5th wire
Nice mains power control project for both convenience and safety.
Maybe I missed it, but at the end only the manual On/Off switching functions were demonstrated. The switch's actual internal NVR feature was never shown to work. With the tool on and running, the orange cord should have been unplugged causing the tool to stop running because of the loss of power into the NVR switch. After the orange cord is plugged back in, the tool should continue to remain off until the NVR "On" button is then pressed again after power is restored. Pressing "On" during the power outage will also not reapply tool power when the main power returns.
As a side note, when using friction mounted power strips like that the one you have, I like to add another screw or bumper along the side of the strip that needs to move away from the main (hidden) mounting screws before the strip will come loose. This prevents general vibration or tugs on the cables plugged into the strip from pulling the power strip off the main mounting screws by accident.
Very useful video - thank you! I'm slinging a 1400 watt router under a table. Would the NVR switch you recommend be sufficient for that? Also I understand that some routers require a device to by-pass the switch otherwise you would have to manually turn the machine switch on and off - an obvious drawback.
Great video could I wire one of these into my router cable if I’m only using the button for that one bench
Brilliant!
Cheers! 👍
Thanks Andy, workshop joiners aren't by nature the most health and safety minded folk so this is a very good tip. Not sure why you painted inside box, is that the OCD thing you mentioned before 😄 and I hope the router was unplugged before you put your tongue on it!!!!!! I had to look away 😂😂 Thank you for sharing 👍
Ha ha - painting inside was mostly OCD but I justified it to myself since it makes it easier to see the wires! 😆🛠😃
Nope, sorry, those are very brightly colored wires. It's simply OCD. ;)
I'm a safety freak too. The old aphorism that the only real craftsman is missing a few fingertips is complete bullshit. Safety is #1. Safety is all.
I do electric model airplanes. The previous generation planes with gas motors were OBVIOUSLY dangerous when they were running, and they couldn't start by accident. The newer electrics are -very- easy to start accidentally. There are a couple of important safety steps to prevent 'unintended startups'. I've witnessed about half a dozen! Fortunately no one hurt by any of those but know of half a dozen more that caused fairly serious human damage. I have personally caused -only- -one- unintended startup, and that scared the furry green shit out of me. Before that I thought I was being safe. After that I got truly militant. And I don't hesitate to call anyone out that I think is being unsafe. Not just for their safety but also for mine and anyone else who happens to be nearby.
I like this 'default off --two on switches' concept. It affects me very little but I'll keep it in mind.
I'm just getting into the planes thing with my son! I was in to r/c in a big way when I was a lad. Great stuff! 👍🛠
That's hilarious. I was thinking that the orange cable is cool and I'd like to get some of that. Each to is own lol
Ha - the colour is great but it's just horrible to work with. 👍
Did one like that but put it permanent on my circular saw bench.
but the portable one you could put it on the floor to knock off with your foot in an emergency.
👍😀
How is the switch wired, you were not clear when making the video. Thank you.
Can you tell me which terminals in this NVR connect to router and which terminals connect to supply power please
Hi Andy. Great video please excuse me for how much of a newbie I am. Love the video but did not understand the wiring at all. I am in Malaysia and we use the exact same wiring as the UK. I have an nvr switch from a dust extractor that did not need an nvr and is on a remote and would like to wire my router setup exactly like you did but I have 4 connections in mi nve: 13/14 and 23/24 and the a 5th I/0. And not sure how to do any of the wiring. Our colors are the same. Is there a way we can chat about it ? Michael O

Hello andy, I am a Handyman in my home boundaries area. I have a dewalt DW745 table saw.but some reason I don't get correction measurement after making a cut, now please make a video on dewalt DW 745
Measuring Label or how to get correct measurement. What is the white coulume of measurement represent and what is the yellow measurement represent presented on dewalt DW 745 table saw
How do you integrate NVR with an automated vacuum switch?
I have possible a stupid question. I added a magnetic paddle type switch to my table saw. Is a magnetic switch a type of a no volt release switch?
Thought you might show the wiring diagram or did I miss it? My NVR did not come with any terminal descriptions
Great video Andy and I totally agree with you that an NVR is needed. I am contempalting on putting one on my Dewalt DW745 table saw as I think that its dangerous to use it without a descent one, the manufacturers one is PANTS, LoL
PS, where did you source it from, do you have a link please?
I just got the Kedu one off Amazon (just search for NVR switch) - kind of mid price. Didn't want to go for the cheapest lol. I find the switch on my DW745 is in a terrible location - I always have to 'hunt' for it! 👍
You appear to use a blue crimp connector on neutral and a red one on live, as though the crimp colours are for that purpose, but the crimp colours are for different cable sizes ...
Nice except for four gang which causes a hazard. Best practise to have separate NVR for each tool.
How does it cause a hazard?
You can have multiple tools connected so that you can switch on for one and another will start. Small risk for you as you usually work alone but I have seen it happen
Hi, confused how the four gang works in this application, surely if you have 4 tools plugged in they will all come on with the nvr switch, so my bench mounted router will start up unless I've unplugged it, might as well just have one socket. Please let me know if I've misunderstood.
Thats why when changing any blade or bit on any power tool, the cord should be removed from the outlet. Unplug the tool from the power so you don't have that issue. I do like the added safety of these switches though.
A very very good tip Andy and folks please remember, it’s not just your household trips that can remove power to your workshop. I work for an electrical distribution company here in the Midlands (like what used to be Norweb up your way Andy) and power cuts are sadly all too common. When we restore power at the substation or via HV (high voltage) switching we don’t check that everybody has turned their stuff off we just “whack it back on again” so to speak. The time it is off could be in excess of an hour or more so it would be very easy to forget what’s on and what’s not.
Wise words! 👍
Hi Andy, long time fan. I've watched this vid about10 times now and love it. qq though (and anyone can answer :-) ): at the end of the video, where you test it, isn't the tool supposed to stay "off" when you press the green button on the NVR? I thought that was the whole point of this: for the tool not come back on when you press the green button again? I must be missing something here 🤔 lol
Yes … bump this thread up. I am confused also.
I thought the power would remain OFF once the NVR switch was used…
Until the user positively reconnects using the green ON switch. Did I miss something ?
I have just subscribed. I chuckled at one stage. Get yourself a sander cleaning stick for that disc sander . Axminster sell them. Also on eBay.
Welcome to the channel Jim! 👍🛠
I just use a screwed up plastic bag to clean up my sanders, since there seems to be no end of waste plastic about!!
I know you're not an electrician so I will research else where too. But is there any reason you know why I couldn't wire one of these into the ring main for my workshop so all the sockets are connected to it?
Is the NVR you used here a magnetic switch or a relay style switch. A couple of my tools have a magnetic switch on them and the removable on button has a magnet on it and if you pull that on button off no one can start the tool. The magnetic on button acts as a key. If the on button is in your pocket or put on the side of the tool no one can start the tool. And it also shuts the power off and will not start back up if the power is interrupted. You have to hit the on button again.

Hello friend. Do you know of such a fault with this type of switch my switch is the DKLD DZ-6-4 15A 250V . Sounds like the off button when switching the machine off, has a vibration in the switch, like some thing is pushing from the other side. Can you please tell me if this is normal.
Good vid, just what I was looking for. Could have used a little more info on the actual button wire up though.
Cheers! Wiring deliberately not shown as specific to switch and not to be touched if folk aren't competent with electrics. 👍
@@GosforthHandyman I have a KJD12 which I believe is the same as the one in this video. Any chance of seeing the wiring diagram?
Would an rcd plug work in place
Someone clearly didn't read their router manual .....Page 967 - it clearly states NOT to lick your router bits!!!. And just in case, here are some of the other things you shouldn't do. ..... Don't stick them up your nose ....Don't swallow them ... Don't drop them into your bacon sandwich ... Don't rub your willy on them ....
Lol, yes... I guess they deserved it. 😆👍
wforl That willy one is that true? I thought that was just a phallusy! 😉
Nice little wire up job and set up there, there's nowt wrong with orange cable, at least you can see it clearly in your workshop. Keep up the good work.
Barry (West Kirby, Wirral)
Cheers buddy! It's just really plastic-y - I want to get some of the rubber sort of stuff you get on Festool tools etc... can't remember what it's called. Costs a fortune though. 👍😆
Does the R.A.F square bashing camp still operate in w/k I was there in 1948 . ?Just going down memory lane
Ok really dumb question but can I have the NVR switching on the whole of my workshop and run tools with a NVR from those. I'm mainly thinking of having an NVR for my Dewalt DW745 table saw where the off switch is really hard to find when switching it off. But with the inline NVR to one side I could find that a lot easier.
I don't see any reason why not if they're rated appropriately - obviously you'd end up having to switch the first one 'on' first... then the second one, which might be a pain. 👍
I did think about that it's just the switch is hard to find but I'll probably get used to it. Thanks any way. I'm really enjoying your Chanel every time I watch a video I learn something new😀
i noticed that the plug you put on the cord was fused are all plugs in uk fused like that im from oklahoma usa i have never seen a replacement plug with a fuse in it!!!?? nice vid
Yeah, all UK plugs are fused. 👍
@@GosforthHandyman not in US course most are only 120 v but think would be handy sometimes thanks for the info (rod for Wakita OK)
I wired the entire workshop to an NVR and an emergency stop button. Power goes off with the lights and won't come back on until someone turns it back on.
Clever! 👍🛠
Doesn't having a 4 gang outlet negate the whole benefit of the NVR? I mean, if you have more than one piece of equipment plugged in then you could still have an unexpected 'live' tool.
Most of these switches seem to forego the earth contact. Isn't that a bad idea? Or are you meant to wire that directly and bypass the switch?
Earth isn't switched - you wire directly to ensure continuity of earth. 👍
Bit late now but if you put the nvr right against the other end of the 4gang then you wouldn't need the cable running behind your mounting board
Thanks for the tip, I have 4gangs every where.
Trying to use a foot pedal with an NVR is a bit of a nuisance. Had to bypass mine on a scroll saw as I wanted a foot pedal to make intricate cuts and keep pressing the on switch was very inconvenient. This will not suit everyone and will probably be frowned upon but since I am the only person here and it has earth leakage protection in works for me. I have NVR's on all of my other power tools, saws, routers etc..
Good work. However, the plug should have been fitted to the orange flex as the very last task. That way, you avoid any mishaps with your mate coming into the workshop after your phone rings & you've gone to the pub half way through the build.
I use a portable power bar to plug in all my power tools.
which way do the wires go on the switch?
The switch should come with instructions showing where to connect the wires up. 👍
They didn't :(
How do you wire a switch up with no instructions.
It's normally just L & N IN and L & N OUT (+ earth obviously) - but you need to know which terminal is which.
I'm a bit predantic when it comes to electric, I always solder the wires before fitting to the plugs
Solder isn't a good idea, as it leads to loose connections, solder is quite soft and it will creep over time causing the connection to be less tight, this won't happen with the bare copper
Thanks for this, will keep your advice in mind, appreciate it. Best regards Geoff Maddison
If Safety is the name of the game for this video then the last thing you did should've been the wiring to the 13amp plug.... Never put a plug on a length of flex with a bare end 😉
Are you from UK or Australia
Newcastle, UK! 👍
"ASAGEORDIEYAFUKNMONGWHEYAYE"
That's a UK accent, and UK plugs...
And yes, there is a Newcastle in Australia
But you did not show which wire went where !
Really liked the video, thanks for making this, but I could not get my head around the fact you wired the plug first after your safety comments.
What if your phone had rung and your mate plugged it in thinning it was the plug for a tool he was going to use, then realised he had plugged the wrong one in and it didn't start the tool so finds the one he was looking for and plugs that in too, but didn't remove the one you had just wired.
You come back from your phone call/lunch what ever and carry on with the swith end, you are now holding a live wire.
Sorry 😞 just thought I would point that out, do the plug last, for safety's sake, work safely guys.
"and he's got no hands" :D
By my understanding an NVR is a No Voltage Relay, not release
Who cares about the friend that got mangled the blood might of damaged the router
Exactly! 😂
Wow, another person that French kisses his router bits!
Of course! 😂👍
Your example of the person trapping his fingers in the router, not realising the power is still fed, is why in industry they lock off and tag. For domestic despite the NVR, before changing bits, blades etc, TAKE THE PLUG OUT!
I cringed so hard with that story, your mate kissing the router bit gets his face ripped off.
Interesting topic, but wwaaayyy too long introduction....
Really wanted to see how to wire the nvr switch....sorry but wasted my time.
You need to check the instructions for your NVR.
I'd have though if you can't figure that out yourself you shouldn't be tinkering with this anyway.
Great idea. WAY too much talking. 4-5 sentences would probably have been sufficient.
