11:00 - this is why people prefer CZcams to polished TV. We see the human side, you acknowledge that we all have bad days and that’s so much more relatable than a perfectly honed performance.
Hope next week is a better week.
The problem isn’t working the long unknown hours, the problem is finding a partner that shares one’s passion for working them.
True true!
On electricians wages? Even their assistants wage? I'd come and tuck you into bed at night and be round first thing in the morning to wake you too! 😆🤣
I can't get anyone regardless.
I’m studying for a masters in electrical and electronic engineering aswell as eventually a level 3 installations. I could help electricians in several ways in years to come if I’m successful.
Your exactly right
Great work Cory! I found industrial electrical systems to be very diversified. Yes, please do film your work on other industrial plants.👍
😂 Cory: " invite your nan along" 65 year old non-electrician woman watching here, looks forward to the mechanical bit too just because ...well it's all so interesting and I never had the opportunity to do anything like it😂
V20 engine, sounds quite large to me 🤪
What a great coup this job is Cory, makes for good content too until the ridiculous problems with faulty parts. Sods law it happens late at night when it's impossible to get replacements at least I presume it is...or maybe there is somewhere that is available to help on time critical jobs?
Great fun, see you next time, just call me Granny 😅😂👍👏
Nick Bundy would love that draw setup👍🏽 Awesome job as always. 👌🏽
NB said he copied it from OY
AVE has already covered the one click back myth with the drill, since watching his videos my drill bits have stopped falling out 😂
More of this sort of stuff please Cory; this is so cool!
I'm retired now, but worked for leckie board for many years, last few as a fault technician attending LV faults. Lots of substation work, cahnging blown fuses etc. With regard to the phase sync to the generator, when on a training course for connecting 250 and 500 kva trailer mounted generators to a sub station, the instructor told us to watch the ring of LEDs on the generator as they would turn one way then the other, and when in sync the circuit breaker woul close and connect up. One of the lads was watching it very closely, and uttered the words "it's read to close", when the generator and trailer jumed a foot in the air! It turned out the instructor had caught his foot in the sync lead, which was supposed to be connected to the red phase, and carelesly reconnected it to the blue, so it ws out of phase!
I think our meeting with 400A busbar in ØY25 was more scary then this +2000A intake . 😅 God jobb Cory 👍
Drilling and tapping sheet metal is OK for thicker sheet but consider looking at "Nut-Serts" or "Riv-Nuts" as an alternate. They will provide sufficient thread to bite and secure. Remember, a bolt/screw should have 2.5 threads at least fully engaded into the opposite thread.
mmm, I looked up m5 and it has a thread pitch of 0.8, so 2.5 threads is spot on 2mm.
@@petermichaelgreen Yes, that is correct for M5, M6's are more common. The point is a little missed though, drilling and tapping sheet-metal is not best way to secure hardware.
Being able to solve unexpected problems independently in real-time is a highly desired skill in any industry. For some reason it's hard to teach and learn; some people just have it in them and others don't.
Absolutely loved this one with Jamie, the dream team pairing!!!!
Oh really
got it easy with these auto synchroscopes , used to love doing them manually when i was on ships, even got a home brew one made out of incandescent lamps for pairing up small gensets// give it a go some time .. good content.. much more interesting than a board change or a car charger 🤣
Very cool
yeah, the old manual glowlight synchronising and a hand crank switch. Every newbee blow the mains or generator fuses.
☺
Top stuff lad 👍
I fully hate auxiliary cables on primary terminations. At least they have a separate bolt. Seen 6mm control stuff on massive 16mm krimps on the same bolt as the twin 185mm 😂😂
The problem I'm finding with working on the UK's electricity networks is a serious shortage of men and a lack of new people coming into the industry. We seem to be playing catch up just keep what we have going, especially when we get storm damage and are out all night getting damaged parts of the network energized again. This then has a knock on effect when it comes to planned outages. Great video bud, thanks.
Think the biggest problem is apprenticeships for that kind of work. I left school at 18 to learn IT stupidly. Now I am too old for an apprenticeship. And currently working as a butcher wishing I went down the sparky route
@@shaunburns3332 You're never too old to retrade but the problem is maintaining a level of income you are used too. 16-18k a year trainee wage just isn't enough for most. A good way to get a foot in the door on the powerlines is a HGV license and digger ticket.
Welcome to conservative government.
Even with the shortage, I’m questioning wether the private NVQ/C&G are sufficient enough for employers, do you have any opinion on this?
@@chrisj1909 yes because they care more about experience and skill than a bit of paper
One of my favourite videos so far, good to see Jamie in his element as well 👏🏼
And he isn’t complaining all the time 😂
I would hardly call this my element , I had my Clothing on for a start
Cory - use nut rivets and it'll secure it better. I use loads on HV panels
Or Taptites would work
Best you tube sparking video I’ve seen in ages & you managed to keep Jamie from swearing. More like this please.
Less swaring I think not
Cool episode. I thing the general plan is to replace peaker plants with big fat cabinets full of Lithium batteries that top off from the grid at quiet times, and then dump pack as demand goes up. Physically bigger, but less mechanical maintenance needed. There's going to be one big wheel left in a hundred years clocking the grid.
Octopus are kind of already doing this if you think about it… except remotely and having the batteries for free! They use their customers houses as a battery farm essentially
There was a test battery unit constructed in Australia made out of partly broken kia battery packs, with huge capacity
It's on fire right now of course, been on fire for a few weeks, they didn't build the bund walls high enough to fill them with water and cover the packs in case of emergency
At current prices, a lithium battery that can provide 1 megawatt for 1 hour costs the same as a 1 megawatt generator and enough fuel to run it 24/7 for a year.
And unlike the generator, that lithium battery has no be recharged at some point.
Interesting stuff Cory.More please.
Great content Cory , interesting to learn more, engineering Electrics stuff. like the van set up with the Milwaukee Pack out boxes & Sliding Draw , Great Tip ⚡️👊
Great video and I'd thought I'd never see the day, Jamie not swearing on video 😆😆😆
Really enjoyable video Cory, thank you. To be able to see what happens at the other end when we turn the kettle on is quite a rarity. Definitely more please.
Lovely job and great to see Jamie.
Great Vid as always. A little tip to try in the future, place the tap in the drill and power tap the hole.
as long as you use a bit o tapping fat.
Great video Cory, looking forward to more of these
More to come!
Great video, shows we don’t all work 8-5. Love it when you get to test yourself
I remember commissioning a new water turbine inside a large dam which ran a generator to feed into the grid. It shuddered to a halt and when it was stripped down the culprit was found to be a large eel wrapped around the impeller.
Tip for commissioning, if possible back feed up to the generator with the wires disconnected at the generator, will prove all the wiring is phased out correctly.
Great video Cory. I have sold gas engines & CHP solutions in the UK for the past 13 years (nat. Gas bio gas and Hydrogen fuelled). I was also the accountant manager for the CHPs that are installed at the UK&I Center Parc sites. Happy to answer any questions on CHPs if you need any help. PS I now work for a Wind Turbine OEM for projects in the UK&I
Great video and yes more please! One tip, when tapping, turn the tap backward a quarter turn for every turn, helps break off the swarf ;)
And treat yourself to an Adjustable Ratchet Tap Wrench T-Handle. Have both short and long handle versions and wouldn't be without them.
More of this please, its my bread and butter and im sad enough to enjoy watching it out of work.
It's Solar maintenance season now, if you want to see the sorry state some of the Solar farms are built like drop me a message.
Sounds cool! Ping me a DM
@@corymacused to work on solar farms they are in a poor state some of them. Used to work with PUSH energy in there clients sites
There are a couple of these sites in North London. They don't connect to our network but they are next to our sites. Cory you need to visit a national grid site one day. 400kV focuses the mind abit!
Great video, start to finish. Love this channel ❤. Always something new
Thanks! That is great to hear you, glad you enjoyed it 😌🙏
Great content Cory, I really enjoyed it, thanks for taking the time to explain what you were doing in what must have been far from ideal circumstances. More big electrically challenging stuff, please. Keep safe though, I wouldn't want you to turn into a red mist. Any chance of a post-job update, I assume things got sorted?
Glad it was helpful!
Great content Cory. Defo would like to see more
Thanks!
Love the video content. Done 45 years as an electrician could not do house busting. Go for industrial. Thanks for sharing
This is interesting for me. One of my clients makes turbochargers for heavy industry - shipping, construction and power industry, including backup generators etc. Interesting to see behind the scenes from a different POV. Thanks!
Cory, you need to get down to the motor spares shop, get yourself a decent torque wrench and other heavy duty tools 😁
I have the same enthusiasm loved working on industrial electrical factory plants even working through the night to get the work done, always like working with engineers who had more knowledge about equipment than me, 77 years young and still addicted to buying tools 😂, love watching your videos.
Great Video really enjoyed this one thanks Cory and nice seeing Jamie
Glad you enjoyed it!
Great video, really interesting!
I loved this video. It is exactly what I do, industrial but in network distribution that I never had the chance to touch (and prefer to leave to the more competent than me for a long margin).
Regarding the sheet metal work, what you've done works but normally I use some threaded nut rivets.
Although 2mm thick sheet threads is enough for catching a screw I'm always afraid that by any external conditions or brute force of the next one to touch that will rip them from the sheet.
But hey it works and it is enough.
This took me back to the late 1980s. Used to service the power-factor correction and oil filled 11kv breakers in various substations.
Lovely stuff. Bit of bonus Jamie too.
👍🏻
The memories it bring back of walking with Dad around HV up to 132KV substations as kid with open and live switch gear. He was brought up in the era when some houses still had DC feed pre-standardisation. I thought nothing of doubling up a socket live at home, with my Dads insulated rubber gloves, 4 sizes too big and not tripping the house.
Better that fuse mounting plastic broke now rather than being just 'on the edge' and breaking later, when unattended , through vibration.
Great video loved industrial work. For tapping the holes in the plate you can use a drill tap or put a clinch nut in. Keep up the good work
Great video 👍 i work on maintaining these generators all over the country. Good fun!
I have some degree of familiarity with railway electrics so I believe I _should_ feel comfortable around 25KV OHL or 50KA DCCR...But seeing Cory working on that 2KA equipment still sent a few chills down my spine even though he'd shown _and told_ us the NG end was locked-off! 😀
Thankfully, the only thing I actually work on is my own consumer LV stuff. Probably just as well, all things considered! 🙃
Love those Mersen fuse disconnectors, got the 2 pole version on my DIY Home battery.
Good job Cory and good to see Jamie.
Really
Jamie who
I really liked this video. Makes a change seeing electrical work different to the ordinary. Was a pleasure to see what Jamie gets up to outside of the electricians podcast.
It’s part of my community service
3:30 I once had a chance to visit a 22kV substation during construction. The switches were at ground level (with these nice enclosures, and a panel on it, all made for human interaction), and the massive cables were fed through the basement. Visiting the basement with these cables, and the cable boots exposed, some lying on the ground to be installed, down there it looked like NO HUMAN SHOULD BE HERE, it was quite a bit frightening for me - even I *knew* 100% the cables were not live.
Also I once visited an exhibition in a museum on 90 years of Hamburg subway, and they had recreated a bit of subway track at the entrance, and to get into the exhibition you had to get over this recreated bit of track (really!), which including a third rail. It all looked very very real (they even had a tunnel enclosure and dim lighting!), every fiber in me seemed to scream: "Don't go there!!!".
Fantastic video Cory! And a PG Jamie. Lol. More please!
Glad you liked it Jim!
Love the variety in your content - it's fascinating for a non-electrician.
Thank you!
Let’s see some more heavy duty stuff. 👍👍 Good video Cory.
Is this why my power kept going off (near Bournemouth) the other week 😂 Corey messing around
Those high power tails should be bonded to earth when you are working on them.
Facinating... Subbed and liked
I have worked with ENW a few times through a company I worked for.... I designed a circuit that could remotely control a panel about a mile away.
It involved a LORA Transceiver and controlled a G50 unit...
It had to have an RF connection (866MHz) because the control room was outside the perimeter of the complex and there was a car park in the way....the alternative would be to dig up the car park and lay cables....
Hope it's still working.....
Awesome work man! 🙏🏼
Nice work Cory
The think I like about you Cory, compared to the Artisan manager, you point things out regarding other electricians shabby work and then show the right way, but you don’t elaborate and go on about it, this is why I prefer your style of methods, your more down to earth, you can correct me if I’m wrong.
Just subscribed. Fun to compare what's going on, on the other side of the pond here in the USA. Enjoyed the video!
Awesome, thank you! 🙏
The dream team we all need. Corie or Jamry? Would be a crime if more of this content isn't released. Excellent stuff guys thanks.
Very interesting as usual Cory 😉
Glad you enjoyed it, thanks for watching!
Good different type of video. Cheers guys
Glad you enjoyed it Lee thanks for watching 🙂🙂
1000% Thanks Cory 👍
I suspect it is far to technical to explain to a politician, that if you have a grid straining under the load, then want everyone to have electric vehicles, and transfer heating and cooking loads from gas to electricity, that there might just be a bit of a problem.
This chap is one of the millions of unsung heroes that keep society from turning into a Mad Max scenario. Thank you young man
Good to see behind the scenes in UK for once 😅👍
Great video Cory, It's much easier to assemble the components on to steel before installing
REAL, WORKING BLOKES SWEAR!
Don't wory mate, we know what ends up on the cutting room floor. 😊
Interesting change of location and content.
Certainly up for more of this kind of engineering.
Get some well earned rest!
I'm on site today testing a new 11kV switchboard at a paper mill. On Wednesday I'm working on a 220-33kV transformer
It's interesting seeing the system from the other end. Might share with my colleagues as we fuss about issuing instructions to DNOs to curtail generation because of boundary constraints.
I used to put the tap in the drill. Best to wear safety specs when drilling metal too.
Really interesting video Corey first time ive seen the inside guts of these large generators we have one in weymouth at chickerell grid station. They are also on about adding a big battery storage scheme apparently rated at 400MW not sure if it will go ahead lots of local objection anyhow il stop waffling now x
I recently started a job building industrial control panels, and it's a weird feeling to see products on CZcams that you work with on a daily basis.
14:00 Rivnuts are usually really good for getting threads into sheet metal 🙂
I picked up a Rivnut starter kit type thing from eBay for about 40 quid, and it just sits in the van until needed, and when it's needed it saves a lot of messing about.
Give us all a van tour sometime 🙂🙂
Rivnuts mate. Nice work Bro.
Thank you Dave 😁👍
Amazing video, really interesting!
Glad you think so, thanks 🙂👍
Very interesting. No idea you did this stuff
There are tapping drill sets you can buy for just immediately ripping a threaded screw hole into sheet metal btw without the need for pilot holes. I've seen a lot of machinists use them. They're basically just normal drill bits with a tap set half way through them.
I’ve got a set but with most of my key sizes missing 🤣👍🏼
I quite enjoy industrial jobs. More please!
Looking forward to seeing more of the bigger stuff. You can get only so much content from domestic house wiring before it becomes repetitive and boring.
Cory, what you really need is some good spiral pointed (!) taps. Those are superb for throughholes like the ones you are threading here and you can just pop them in the drill and ram it through the hole with a lot less risk of breakage.
Just found your channel and subscribed.
I used to be in a very similar line of work, but predominantly on large DC systems.
However, that was back in the days when drills all had mains leads and chucks all had keys.
On the subject of chucks; the 'single reverse click thing' has been mythbusted several times now.
I would have also used 'nutserts' for fixing to such a thin panel.
Interesing stuff, closer to the stuff i do on a daily basis. I some times wish i could record the stuff go around doin.
Speaking of heat recovery, I am a propane delivery driver, and I met this fella who owns tomato greenhouses. next door to him he has a diesel motor powered sawmill. so he made a deal with them to put a heat exchanger before their radiator to steal that heat and pump it to his greenhouse. so that way he saves some money on propane to keep his greenhouse warm.
Nice video, I think that Conrad are the only company who build and operate their own sites in the UK!
Lully work 💪🏻 when you done the cut outs on the metal sheet you should of used some black grommer strip 💯
It's OK to vent Cory, good to see you're human (I was concerned...🤔😉). This kind of video I find there most interesting - stay well mate :)
you are living the dream there big heavy machinery playing with big boy tools working with one of the best jamie blatant what else could you ask for. i wouldnt worry about not having the time to film everything you doing important work if you film a few minutes explaing something you find interresting that will be enough for me.
Hi Cory, in the past I have designed plenty of panels built them and wired them, Mostly for refrigeration systems ( mcs's, contactors, stats, timers, din rail ETC) single & 3 phase 440V and mostly locked enclosures ho and swa up to 16mm and pyro all different sizes & cores and not forgetting singles. But I would have loved to work on bigger projects, heavier cables and higher voltages etc! Also subscribed 😁
Have you tried Threadforming screws? If you drill a 4.2mm the pan head screw will make its own thread when driven in, also when you take it out the hole is tapped. Use these all the time! They are also known as TapTite screws or TapFix.
Please more stuff like this. CHP is a very interesting field
I love a good rant video!
Nice camera work . Nice effects
Thanks a lot!
Wish I'd had Tradifi 12 years ago when I was shrink wraping 12/40ft boats.
Great video, very interesting to get a look at the gas engine gen sets.
Nice job on the panel , as I noticed another commenter said “riv nuts” or sometimes called “nut inserts” would be great for your line of work they can be used in sheet metal that is to thin to tap and no acces to the rear is required - check them out !
Also AVE has a video on the turn the drill chuck back till it clicks thing think it’s an internet hoax man …..
