cu update to 17th.


Megaohm7

Question

Good evening

A customer has requested some additional sockets in the lounge, however the c u is an old wylex type board with the push button type breakers . Because there needs to be additional cable chased in am I right in thinking that the board needs to be brought up to 17th ed ie rcd protection to cover the new works . I know that it will be notifiable of course maybe a good time to get assessed as I am not on the competent persons scheme as of yet but have had to turn down jobs in the past so I think it's time to get myself sorted out on a scheme .

you could always add an RCD somewhere, but chances are CU could do with being upgraded, and i can almost guarantee gas/water earths will need done

Those Wylex push button MCBs need to be replaced at least. If you check you will see that their short circuit rating is quite low, can't remember what exactly, possibly M3 . Never heard of one failing but I think the lowest you find now are M6.

iirc, some are M1.5. but either way, the BS1361 or BS88 will provide backup if needed. still a good idea to replace the board though

I agree an upgrade to the C.U and possibly Earthing & Bonding will be preferable.

If the customer wont play ball here then just install an RCD fused spur at the point where you extend from the existing circuit, you will still have to ensure Earthing & Bonding are up to scratch though !.....The plus side for doing it this way for you is that it wont be notifiable Would still advise organising yourself on the Competant Person Scheme route as soon as possible if you are a practicing spark on domestic properties...save you hassle in the future.

Still advize

Thanks for your replies they are very helpful. I will advise the customer accordingly to the safety benefits of rcd protection in particular . If customer does agree to a cu change and wants it done sooner rather than later then I have a registered domestic installer who will cover the cu change and testing and certs but for now I will be looking into going down the registered person scheme route myself. ohms

I have been told that the NIC assessor will want to see the EDF certificate to show that the main head fuse was taken out by EDF and not your self for safe isolation. This is why I would not do a CU change for the assessment

Never heard of that one before Matt....seems a bit harsh. Maybe it would be wise to choose a job with an existing DNO Isolator .just to be on the safe side then .

I did my own CU for my initial assessment .. snipped the meter seals, changed the tails and informed EDF post job ... chap came out a few weeks later to seal, glanced at the cert and sealed it again, no problem no cost .. ... my elecsa assessor had no problems with this .. agreed with me that there was no realistic other way around a cu change nowadays ..

Not sure i'd even bother letting them know now, just reseal it myself ..

I'm planning to do my CU for my assesment sometime fairly soon, has anyone actually had a problem personally with the assessor asking about the fuse??

To be fair you can not assess the fuse characteristics by looking at the fuse holder.

You are not allowed to cut the seals so there is no other way to define the cutout.

No assessor would ever mark you down for not putting the exact fuse rating down on the certs, however important to the installation this is.

Most of the older types were predominately 60 or 80 amp and not the usual 100 amp found nowadays.

He would however expect you to know the type which is found on the side of the carrier.If not the actual fuse rating.

what if you didnt get one?

round here DNO use Wylex REC2 isolators. install one yourself and no-one will ever know...

and by your logic, using a re-wire is a no go area too, unless you leave the old board in....

You could ascertain this by enquiry.

Getting a bit confused over this issue. Admittedly, in my 'unofficial' days i've snipped a few seals but on all the weeks of my recent courses the tutors have emphasised that you NEVER cut the seals or remove the fuse. What's the general opinion on here? I'm doing my CU change for my assessment (and because it's in sh*t order) in the near future and don't really want a red card before i've even begun to play. Not sure on the situation regarding isolators in YEDL area but I may check on that.

NEDL & YEDL are both owned by CE electric, so im guessing YEDL will use the same REC2 isolators are NEDL. so fit your own?

I'll probably do that. Am I being a little over concerned about removing the service fuse myself? Seems to be a lot of conflicting views on this.

adding an isolator can be done live if existing are large enough (well, it can be done on 6mm

Good evening all,

Did my NIC assessment partly on a CU change and the subject of who took the fuse out was never even mentioned.

Have not come across many isolators in this neck of the woods. ( Eastbourne)

Some interesting replies here , just goes to show how much of a mine field this industry has become and most of it does seem to be more money orientated than it does for safety .. :o:|

whats safe about not being legally able to isolate a supply?

and for all the proof you need that the DNO is more interested in money over safety.... PME/TNCS

Not too keen on working live. Not done a lot of these so i'm sticking to dead work for now. Meter tails are 16 so, although I could leave it, it would be a good opportunity to change to 25.

i have a mate who belongs to the NIC and that his mate failed cos he had no evidence that edf came out to remove the head service fuse...
