A plumber friend (yes, I have one!) has asked what training he could do to support his fitting of boilers/heating systems etc.

I said C&G 2382 - Wiring Regs would be a good start, at least he'll learn you can't use the cpc as a switched live then!

After that, C&G 2392 could be a good one, I&T of single phase installations.

Also, the boiler companies do their own courses on wiring up heating controls (WB is 2 days, so maybe a bit more in-depth than I would expect).

Are there any others that he could do to help him be safe and mak his wiring compliant?
