How many of you cross-bond the pipes into the boiler? I've had a sparky tell me that it must always be done in 10mm[SUP]2 [/SUP]but he is a bit of a gobby tw@ who thinks he knows everything and likes slagging other trades off.
I've always been told that as the boiler chassis is earthed, as long as resistance to earth is within limits, there's no need for cross-bonding. If I'm doing a swap and there's cross-bonding already there I'll re-attach it but otherwise not. Anybody know the definitive answer?
I'm happy to be corrected if what I was taught is wrong, just want to know what's what!
