Tails inside consumer unit bare copper, not terminated correctly - C1 or C2 ?

[vwes59]

Ok, I'm in the middle of an EICR for a client. The tails are going into the consumer unit in separate holes (It's metal, so that's against the regs), and then inside the consumer unit they have been terminated in a really shoddy way with bare copper showing. Now copper showing on the tails is a C1 outside the CU, but is it still a C1 inside the CU given you would have to remove the cover before risking an electric shock ?

pictures please. from you description, I'd hazard a C2.

IMO:

Tails entering through different holes: C3, based on a JW vid I saw where he tested this at ~100A, and nothing really happened.

Copper on show: I'd need to see a photo, but it would have to be really bad to warrant more than a C3. CU's full of live copper after all.

Definetly not a c1 although it is poor workmanship the terminal screw is live and can be touched whether the copper is showing or not and that does not receive a code. It does not present an immediate danger. C3 at most.

No more than a C3 as its within an enclosure. Could note poor workmanship too.

How much copper ? 2 mm then nothing to worry about , 2 cm then its rough as my badgers arse

I'll post a photo tomorrow, but it's a lot, at least 1cm or more. The only place copper should be showing is at the neutral or earth bars, the bus bar should be covered. As a matter of interest the codebreakers book states any copper showing on line conductors is at least a C2

Aside from opinion on here and Codebreakers which is generally considered a joke what do you think and why. To compile a Report you must have enough competence and knowledge to assess the type of installation you are working on.

Supposedly not an issue, according to BPG4:

Items that should not be listed as non-compliances with BS 7671 and do not require reporting (Mythbusting):

Absence of barriers inside a consumer unit (provided the cover is removable only with the use of a key or tool)
