THATS THE WRONG CONSUMER UNITđ±đ±đ±

- So I am fitting a new EV charger today and unfortunately the customer had already had his consumer unit replace but with the wrong one even though he had specified for a ev charger

Cheers Mike, great video we also use Tradify from your recommendation is pretty good software to be fair. We use it on a daily basis now to run my company. When I first looked at the dual rcd consumer unit I thought, maybe you could fit a miniature Rcbo between the main switch at the first RCCB but for the price of those little consumer units with SPD why not. Even though we fit SPD on everything I still do not buy into the idea of it. I think itâs complete nonsense, the manufacturers rewriting the regs for us to sell their products. In 25 years in the game, Iâve never seen where surge protection wouldâve helped. Living in Hertfordshire, and from the last regulations I was in the Twitter zone of it all.. and probably until we can test it for ourselves. Will I ever think itâs not a waste of money. Thanks again. Enjoy your Christmas. About the double pole, RCBO hand on heart, I always thought until this year until JB electrial on Instagram, showed that not all RCBOâs arr double pole, I was taking it for granted they were.
Hi buddy I hope youâve had a great Christmas. Yes I didnât know until recently about the double pole rcds as like you I thought they all were so when I found out I thought I would share the info.
Have a great new year buddy đ
@@GreenHawkConstructionltd Did you had to put another henly block and take a new consumer unit from there just wondering that since there is also one consumer unit there already in the garage so where did you take the power from? I know that for the garage you have to take a new line from the hanely block or box at the orgine somewhere but now you got even a smaller one so if you can share a bit about that, it will be great.
Cheers for that nugget of information, been fitting FuseBox for the last 2 years and never actually realised that the full hight RCBO were single pole switching⊠probably down to ignorance on my behalf.
Just shows how useful and essential watching CZcams content is to up skill.
Thanks mark !!!!!
Wishing you a Happy New Year. Thanks for your videos
Merry Christmas Mike!đđ
Think you will find they are double pole rcd units and type a , suitable for ev charging
Cable cleats are upside down đ
Hopefully, that will hold the wall together đ€Ł
Thanks for the videos and I hope you have a successful 2023 - did Pablo pull the main fuse?
I think we've all got a Pablo friend to pull that main fuse! Just cant understand why the industry wont let us qualified electricians do it?
I've had many a conversation with sparks fitting EV that were not aware of needing double pole RCBO's and also not aware that the full size RCBO's were only single pole and neutral. It's one of the main things to go under the radar. Also simultaneous contact assessment if using TT for the charger is one that goes under the radar.
I like the big crack up the blockwork.
Had the same on a recent job with a cheap consumer unit from toolsation with no surge and type A RCBO
The zappi v2 has 30mA Type A RCD & 6mA DC protection built into it. So the RCD would only be required to protect the cable at most. If using SWA a RCD wouldnât be required at the origin. You have now got no discrimination between RCDâs now between the inbuilt and the one in the db.
It could be argued that it doesnât need RCD protection at all in the db with the cable clipped especially if using SWA. The high tough may be different due to the risk of damage from the environment.
On a positive though good install and nice and neat. Thereâs too many people who just lob it in and run.
I agree , no need for the rcbo in the new dB
Just to throw this inâŠâŠ. Not sure the in built RCD complies as it doesnât have a test button đŹđ€ NIC EIC webinar covers this.
@@leerudd8468 interesting,
The Myenergi documentary and installation forum technical experts (from myenergi) seem to go along the lines of Generally there is no need to fit whatâs often referred to as an upstream RCD unless there is a risk to the cable between the supply take off point and the Zappi, for example if the cable was buried and there was a risk that someone could put a spade through the cable whilst digging.
However I would be interested to see the NIC webinar on this.
How would you âget aroundâ the lack of discrimination in this situation?
I guess manufactures instructions over rule I guess. Such a grey area yet again.
The zappi self-tests its RCD functionality at the start of every charge. And no need for an upstream RCD even with a non-armoured cable as long as it isn't buried (ie clipped direct). I guess that if you do have an upstream RCD to protect the cable or for any other reason, it should be a time delay one but they tend to be expensive.
Excellent video!
Hello Mike, itâs great to see one of our local lads putting out some interesting stuff not filled with self importance. Iâve seen you around in your van around Coventry, be good to see you at some point. Happy New Year mate and look forward to seeing your vids in the new year. đđœ
Merry Christmas buddy yes if you see me about feel free to come and say hello. Glad you enjoy the content have a great new year đ
Lovely little install. Some info on your testing procedure with EV would be cool. I couldn't see your feed to the new board, am I going mad?
CP Fusebox 30 ma RCDs or RCCBS are double pole mate.
With the cable clipped direct and the RCD built in to the Zappi, is another RCD required, or could an MCB be put in directly off the main switch in the fusebox board (looks like the installer put a blank in perhaps for this purpose?). Still probably needs an SPD adding though I guess...
No RCD protection needed on this installation
@@yuliyanshirokanski4929 zappi rcd doesnât comply as there is no test button . Zappi need to update
â@@robswingler If there is an electrical fault to ground and the RCD operates the zappi display will show RCD Tripped!
To reset the zappi, make sure that the fault has been removed and then press ïżŒ button for three seconds.
@@bramcoteelectrical1088 that's not what I'm talking about
@@robswingler it's what I am talking about bud
Great install what's the song u used when doing the time lapse of the install
As You Fade Away by NEFFEX
Could have added a dp rcbo to that board and a surge at source.
There is 1 Blank in that Board - The Type 2 SPD would require a B32 MCB for this. Therefore there's no more space remaining for an additional MCB or RCBO for the charger....
Good video buddy.
Double pole or single pole? It's easily identifiable by just reading the diagram on the front of the rcbo
Good vid. Those BS61008 RCDs on the dual RCD board are, in fact, double pole. I'm not too clued up on EV charger regs, but is there a requirement for surge protection?
All new consumer units should be fitted with SPD. It helps to protect the sensitive equipment in the dwelling. Most new electrical stuff contains electronics which can get fried easily
@@sergiofernandez3725 thanks, but that's not quite what I was getting at.
Is there a regulation that implies that surge protection must be provided for EV chargers? If there isn't, (which I don't think there is) then the charger could have been installed on the dual RCD board (as many are), and the additional board was unnecessary.
@@andrewcadby amendment 2 requires all new installations to have an spd installed or a sign risk assessment from the customer stating if any damage or issues arise its on them... most people think for extra ÂŁ50 screw it
All RCDs rccbs are double pole.
Could you show us splitting the tails which you mentioned
It'll be a pair of Henley blocks and additional tails.
Considering the sort of âEVâ I'm accustomed to, I doubt that Zappy charger would be able to accommodate those levels of current... đ
(Disclosure: The sort of âEVâ I normally use travels at 320km/h, is powered by a 25kV 5MW overhead traction supply, and is known in French as _« Un Train ĂĄ Grande Vitesse »_ đđ«đ·â€âđ„đ)
Ultra ev cable look a bit pissed
Did you mean '30%' (9mA) not 30mA?
I think he was getting at the tripping total accumulated from the group of circuits on each rcd.
nice video just could you turn the audio down a bit next time thanks
It's a bit overly loud compared to the rest of the video haha
when you leave the video in timelap, you cant catch or learn exactly how you doing the job. I think its best leave it normal and those who are not patient to watch can fast forward
Lavly
wonder what the charge will be when these ev boards have to come out !!
Teriblble music and way to loud!!!
Sorry always have to give any videos I see with thumbs down because of the background music being played. It drives me crazy.
That doesn't make any sense. What are you trying to say?
