No cpc on lighting and no neutral continuity on kitchen ring

[Muzza115]

Hi All,
I recently replaced an old rewirable fuse board for metal split load rcd board. However on testing prior to replacement I noted that one of the lighting circuits doesn’t have a cpc. I’ve put this in the EIC for the new board that no cpc for lights, advised client that needs rewiring and advise against metal fittings accessories etc,is this the right course of action to take? They do already have metal fittings on this circuit, Is rcd protection enough to cover this? Also the kitchen ring has no continuity on the neutral conductor, I’ve had all the accessories off to find it but can’t, I’m assuming the break maybe in a buried joint box as the kitchen is an old extension. What’s the best course of action to take regarding this please?
Thanks

Before, on a certificate, no CPC to lighting was classed as a c3 with advice of no metal light fittings. But in the 18th it will be a c1 or c2. Basically a fail

What do you base that statement on?

Yo

What do you base that statement on?

u took your time to get in on the argument Ant

So poor Mrs Jones, who can't deal with BS 3036 fuses anymore will HAVE to have her lighting rewired before you would change a fuseboard ...........................

Bad practice IMHO

What do your scheme say?

The installation has to meet requirements so mcbs will operate in the times stated in regs, whoever is responsible for changing the board has the duty to test the circuits and they have to meet requirements. Otherwise RCD will not trip.

Had to check my regs book.

I've seen a RCD protecting a lighting circuit (with no cpc) trip a RCD....

Do you understand how RCD's work?

Right OK good to see you are on the ball

This is irrelevant to this thread - the OP's doing a CU change , not an EICR

Regs, looking at old certs dated 2013 and then phoning up and asking the person issuing the certs that he passed an periodic inspection even though there is no earth to lighting. I always believed with my old company that you had to earth no matter what. Apparently you could get away without CPC to lighting before, as long as there are no metal switches or fittings. That's all changing now.

For you're last question Murdoch.

If there is no R1 + R2, it's pointless to have an RCD. Earth continuity, is a must. RCDs are for earth faults. You tell Mrs Jones that you replaced her board with an up to date version but will not have the benefits of a new version, but it's fire protected because it's metal. Might as well change the 3036 fuses to wylex switches in that case, it's more practical.

More work for you Pete.

Exactly, there can not be any C1 or C2, otherwise he cannot issue an EIC. All has to be earthed and all mcbs and RCDs need to meet the requirements of the regs. I will never issue a EIC knowing that's the earthing to the lighting is not in place and I will tell Mrs Jones, I cannot continue with the board unless she pays me to rectify the issues that will prevent me from issuing an EIC, because I am the one responsible by law, I am the one who signs off the work and I am the one who notifies building authority.
