metal capping / earth?

[Johno]

do you use metal capping, and if so, do you earth it?

you can if you whant but if your capping is to short and you put a earth wire across both you will need a expection cover to check the joints as per bs7671 and it whould be a total pain earthing every pice of capping so for me NO i would not.

Use it occasionally but never earth it , there is no point
