mains change

[leekemp85]

I have been asked to change a mains board in a small office as there are no spare way.(the building was tested a few weeks ago and I have been asked to do the work that failed.)

Am a qualified electrician registered as a sole trader but not yet in the part p scheme am I legally aloud to do this.

And if changing an mains board will everything need to be on rcbos or just the new circuits the other electrician put a code 2 that circuits were not on rcd (I thought this would be a code 4 as you can change every circuit to rcd just because of new regs)

many thanks

The regs do not differentiate between domestic & industrial.
If a cable is buried less than 50mm without earthed protection or etc or etc, then rcd protection is needed.

wrong, its a controlled enviroment, I have taken the ECA to task twice on this and both times they say no rcd

I bet you've been searching for that for ages.

On a more serious note though I believe the statement "Under the supervision of a skilled person" is appropriate to this thread.

That is for RCD protection on the socket outlets, not the installation method.

As Jason says, that's for socket outlets.

Take the ECA to task again.

A small point to add, the OP hasn't stated what inst method he has on this install. Seems we're getting carried away without all the facts being present.

Please enlighten us Lee.

How many times should I take the ECA to task? 2 different technical experts at the ECA on different occasions have stated that no RCD protection is required as an "ordinary person" should not be putting up pictures etc etc. Not trying to defend that I have put sockets in without RCD as all my commercial installations are either floor box or 3-compartment trunking but if a respected organisation like the ECA is stating that, where do you go to get 100% correct information and you also question all other answers as is the case now.

I've also taken advice from the IEE on this and they effectively confirm what sparks is saying.

Thanks Chrissy, I was beginning to feel like I was banging my head on a brick wall

Fair enough, but im only pointing out this "ordinary persons" is applicable to the use of socket outlets and not the installation method.

If the circuit was surface run and they were not for use by ordinary, non-instructed persons, then RCD not required.

If the cables were buried with no mechanical protection then RCD required as per the norm in most cases.

Can only give you the info that has come from the ECA and now looks like the IEE
