Re: Circuit breakers
Yes, it does seem as if the electrician I used back in 1993 cut some corners. He was (supposedly) a pro, and I know he was trained on a nearby Ministry of Defence site. I think he's employed pushing up daisys now.Given that the steel earth spike is 50 years old, I'd suspect that much of it will now be non-conducting rust

These have a designed leakage current built into them and if using too many that leakage current could trip your RCDs off.
Cheers mate.

.Isn't it curious that we have to have our cars MoT'd every year, but our home electrics have no scheduled checks on them at all.
Thanks for the advice
