just going on a job for a friend to make off pyro ends,2L2.5 and he has been extending earth tail of pot using 1.5mm single.this cant be right if cpc is 8.2mm.any advice?

when you tighten the gland to the box, thats earthing the back box anyway, but if you think about it this way, normal 2.5 flat cable has a 1.5 earth, which is adequate for protecting the circuit. 1.5 will protect that circuit too so it makes no odds.

Trying to put together a half decent download for working with MICC seeing as no-one seems to teach it or test students on using it anymore.

Not finding a great a deal on the net regarding the high temperature glazed seal pots that use the resin as opposed to the standard compound. If anyone has anything hidden away on their PC's and wouldn't mind sharing I'd like to see it.
