Moving the CU

[RogertheBodger]

I would just knock the wall down and hang the cu on the back of the new door, no drama, 2 screws, easy.

Move the cu extend circuits issue MW for each circuit.....................simples.............why the protracted debate?

Because were british and never agree about anything, our Island is 900 miles long and yet we cannot even speak with the same accents lol, never has there been a country like ours in history, we love debate and love trying to beat each other, thats just brits for you. :santa3:

A cert per circuit? So eight or ten certs? Hell's teeth you like your paperwork!

Morning

don't think the OP (Hi Amp) was going to extend any circuits, is that right? Just move the CU. I assume from your post the situation did not require extension of any cable?

 

[imago]

A customer wants a consumer unit moved about a meter to one side, because she's converting the garage and wants to put a door where the consumer unit is now.

Moving it a metre must involve extending the cables surely? Especially if a door is going where it was originally.

Installation cert for me.
Removing old CU modifying every circuit then re-installing CU.
Last person to work on it.. you
Extent of installation affected by your work.. all of it.

Good call,but surely hanging the CU on the door will require all circuits to have new flexible cables which,will require testing.Its a mine field....

What is a completion certificate?

Ok, so you are moving a CU, you need to extend the circuits, appropriate box, wago's etc, extend out no worries.

You are not doing an EICR. You are doing a CU change. You do the standard CU change tests, Ze Zs's Insulation tests, all that you need to do to fill out an EIC. In the EIC is a section that details the extent of the work carried out. You put 'Replacement of consumer unit and associated testing only' so long as you can fill out the cert honestly, you are covered.

Should you uncover any problems during the testing you need to to do to complete ther EIC then yes, you need to investigate, eg you cant just shove an R1 of 0.70 in there followed by a 2.5 R2, you will need to investigate that, but that is as far as it goes, if it all adds up and your insulation tests are fine, you are covered.....

 

[not clever]

but its not a cu change, it is relocating the same cu. Unless i read the post wrong which isnt unknown.
So how many when they extend a ringfinal issue an EIC? not me.

So if its the same cu just relocated (no change in ocpd's or rcd's) & the circuits require extending why would you complete an EIC?

If it means that you have to extend ALL of the cables the very least you shouid do (IMHO) are R1 + R2, IR and Zs on all affected circuits.

If there's 8 circuits you'll need to do 8 x MWC or 1 x EIC - EIC for me.

 

[MDJ]

Certainely a difficult subject for us all to agree on, but removing all circuits, tails and earth wires, plus extending them all and confirming continuity and live tests is quite a complex job really, imagine the trouble if something happened after leaving site, and the problems via insurance matters, a Completion Certificate would be my choice as I mentioned yesterday and to issue these would mean a full set of test results to all affected ciruits which in this case would be all of them, peace of mind and a proper Job done, which bob from the pub local wouldn't do, the householder would be assured a professional spark turned up, imagine handing over a dozen monor work circuits trying to explain doing this job otherwise, or no certification at all lol.

 

[AndyL]

This is not minor works so MWC cannot be used, it specifically says on the guidance note that comes with MWC not to be used for replacement CU. I know OP says he is using original CU but i don't think this makes a difference

 

[SPARTYKUS]

I would say the devil is in the detail on this one.

As mentioned prior, it does depend IF the cables, and which cables, need extending.

I would fully expect ALL cables to need extending moving any CU that distance but maybe one would get away with the tails if its miving closer to cut out, and so on, the same may apply to some/all circuits, they may be plastered in/clipped to the wall in a cellar or a 100 other possible scenarios.


Tricky.

 

[sparky-s-w]

if your extending cables....just do the tests just to be on the safe side. if you dont need to extend cables, then it aint the end of the world if you dont test, but why not test & add the extra hour or so, on to the bill

 

[shazbutz]

I'd test and issue an EIC. I completed a CU replacement, no cable extensions required just a simple upgrade from 3061 to 17th Edition in the same location. On testing got awful Zs results and a Ze way over the max for TN-S. The DNO had to attend and repair their incomer.
You never know what you can find and CYA (cover your @rse) is always to be considered!
