When did the requirement to sleeve the bare CPC come in was it the 14th edition ? I know ive seen a few installs with green sleeving.

The colour green was admissable until 31 dec 1977.

Not too sure an actual reg exists,does it.
It may help to comply with other regs though.

The colour g/y is reserved for earth, but I am not sure earth HAS to be g/y if that makes sense
Earth bars are usually bare.

I asked because i know of a spark who goes round not sleeving bare CPCs and his excuse is that it was not required in the 15th edition and he trained to those regs.

1. It was a requirement of the 15th, I'm sure. I trained to the 15th and I sleeve cpc's.

2. It doesn't matter even if it were not a requirement of the 15th - it is now & he should be working to current editions. F'kin dinosaur...

I suppose he doesn't believe in using RCD's either?

Same here, the 16th became current as I finished college (1991).
Throughout my apprenticeship I didn't once not sleeve a CPC nor work with an electrician who didn't sleeve CPC's.

It all comes under Identification of conductors, if a conductor is to be used as a CPC then it should be identifiable by the colour`s green and yellow and im not 100% sure on this but i think in 3 phase systems that the use of alphanumerical identification is not allowed on cpc`s and they,like single phase must be colour identifiable.

I saw a black earth sleeve in a socket I loosened off the wall the other week.

That would sure confuse a DIYer

Seen a shed load of cookers with black heat-shrink (the word YONGLI gives it away) over the CPC.

Is sleeving really that expensive?

It must be, the number of sockets I see with the cpc's twisted together and sleeved with a single G/Y. Same in light switches.

IT MAKES ME MAD!

THE 14TH with 1976 amendments
reg B5
bare conductors shall be made identifiable---- colours prescribed in table B.4A
Table B.4A earthing green/yellow or green until 31.dec.1977

The 15th with 1984 amendments 524-3
bare conductors shall be made identifiable ----colours prescribed in table 52A
Table 52A protective conductor--green and yellow

The 16th became 514-06-03

The 17th became 514.4.6

Earth sleeving was always one of the options to comply since at least 1977.
