Help with EICR codes!!

[dtec dave]

Evening..I'm after a bit of advice coding an EICR I have done today, I don't do an abundance of them so just a bit unsure.

1. 3 sockets spurring of a ring without a fused spur.

2. Evidence that ring cables had been joined behind the DB, the L & N end to ends gave me the results I was looking for but the CPC was 0.01 ohms. I tested at a socket with the 2 legs at the board out and got a correct reading which suggests figure of 8 wiring on the CPC.

3. Socket circuit wired through metal conduit buried in the wall with metal back boxes connected, the earths for the sockets have been taken off the back boxes.

4. Back boxes not earthed on various circuits

5. Incorrect colours used on socket circuit.

Thanks in adavnce.

1 C2

2 could the metal conduit be affecting the reads?

3 not sure what your concern is with the metal conduit, are the fittings class 2?

4 again are the fittings class 2?

5 please expand on incorrect colours?

1.
do you mean there are 3 sockets spurred separately off 3 parts of the ring? if so, no code.

2.
is the wiring system to the sockets, singles in metal conduit, if so the live and N will be rings but the cpc may well be the conduit system itself.

3. look at 2.

4. are the back boxes earthed through the accessory? if so no code, although i prefer to see a wire link.

5. what colours?
red / black all is good,
green, pink, white etc. incorrect identification of conductors.

is it a flat in a block?
Is it MI?

It's in an office.

No, not MI

3 sockets in a line off 1 socket.

C2

I might cop some flak for this but no. 5... the incorrectly identified conductors... I would probably C3 it. It's not like there is excessive copper on display.

Without digging out my 15th Ed you could use the yellow and blue for single phase identification but I am 99% sure this only applied to distribution and not final circuits.
What are your Coding thoughts OP.

 

[pc1966]

I'm guessing the blue is a L3 phase colour?

Westward10 just beat me to it!

 

[dtec dave]

So it's likely that the 2 T+E ends in the DB join L to L and N to N onto singles, but the CPCs connect to the metal conduit,(this is all hidden somewhere) then the CPC is taken off every back box to connect to the socket. Is this acceptable?? Obviously I can't get R1R2 off this so would I take an R2 reading off the furthest socket? The Zs readings I took were all acceptable.

 

[pc1966]

R1+R2 applies to the circuit, it does not matter if R2 is conduit or cable.

What is important is it is a sound connection, physically and electrically.

So here it is in the 15th Ed.

Well blow me down...every day's a school day!! I'm a bit young for 15 edition, started on 16th.

It was often misread and should only be applied to distribution circuits not final circuits like you have.

Well I just misread it!!
