    No CPC at light switches in plastic trunking

    Not the usual per-1966 sort of "no CPC in wiring issue" but plastic light switches in plastic back-boxes in trunking wired in singles. The lights have CPCs and measured Zs, RCBO trip-time, etc, all good. However, the actual switches lack a CPC. Now I could run in a CPC to meet the last...

    Who do is responsible for the incoming suppy

    I am doing a new consumer unit install on a second story ex council flat. I’ve notice the mains come in in metal conduit with no CPC. On checking further I’ve seen they have split the neutral before the meter and joined an earth cable onto it creating a pme at the fuse board. I believe this can...

Hall light is a pendant wired in 2 core PVC cable, no earth at it. Tested at kitchen light and got a reading, then tested at living...

    No CPC on lighting circuit

    No CPC at switches or light points. All lights are class 2 so a C3 on eicr. But what do I write for r1r2, just a LIM? is that acceptable? bit confused on this.

    Plastic Light fitting with metal trim & no CPC

    I have a couple of lights on a circuit that does not have a CPC. The light fittings are plastic but they have a metal trim that screws into the plastic body. I wonder if anyone can advise me if these are deemed as safe considering the main body of the light fitting is plastic and the metal trim...

    No CPC on lighting circuit ............

    OK, lets have a decent discussion about this as I'm sure there will be a number of opinions! Have done an EICR on a 40 + year old flat. The lighting circuit is wired in singles and utilises the steel conduit as the CPC. Out of the 6 lights and using my R2 wander lead, only 2 have an acceptable...

    Adding to existing lighting with no CPC

    Hi everyone, I am currently installing an additional 4 way CU which is to serve a new extension on the customers house. They have also asked me to alter one of their existing 2 way stairs lighting so that they can have an intermediate switch incorporated (a switch at either end of the upstairs...

    Can RCD/RCBO trip if no cpc is installed?

    Good morning, :) I saw lighting circuits done with 2-core cable (red-black) with no earthing conductor. I was wondering in a case of an earth fault is the RCD/RCBO going to trip? I think if a metal switch or a chandelier becomes live, the RCD/RCBO won't trip due to the missing cpc! But is it...

    Insulation resistance testing with no cpc

    When doing a CU change and lights have no cpc. Every room has class 2 dimmers and lights. ceilings are like 20 foot tall. How would you guys go about Insulation testing? L&n to cpc ain't an option and removing all lights and bypassing dimmers is consequently going to take some time... What would...

    Lighting circuit with no CPC, fail???

    Hi Guys, Just been to do a Condition report on a 30 year old installation. Both lighting circuits are wired in twin stranded steel cable with no CPC. The insulation test is good, but with the lack of CPC, and brass accessories, would you consider this as 'Satisfactory'. No RCD on lighting...

    Lighting with no CPC and installing new CU (Domestic)

    I have the ESC’s guide to replacing a CU where the lighting circuits have no CPC, and this says the initial approach should be to persuade the customer to upgrade the circuit to provide CPCs. If that fails, the guide then includes a risk assessment table (at the back), where it is allowed to...

    Lighting circuit with no cpc

    If on a EICR you were to come across lighting with no cpcs. Is this acceptable. Presumably if it's all plastic ad class II products and fittings then maybe it could be but I'm think really it will need cpcs to be run with it. Even at light switch withe tak backbones as in the event of a fault...

    PME install, no CPC

    Hi guys, I've been called to look at a flat in north London. The flat is in a converted piano factory. Looking at the CU, perhaps installed in the 70's or 80's, it has a CPC. All good. Under the CU is a termination box of some description. The tails come up, through metal conduit, into...
