Earth size for trunking

TJSparks · 2020-05-27 23:20:59

Doing a flat rewire and ran a new 16 T&E to a new outdoor meter cabinet. I ran it down the inside of the external wall which is battoned out, in 50mm steel trunking and bonded the trunking with a 10mm earth from MET, but wondering should it be bonded with a 16mm earth?

10 mm is fine for bonding the trunking.
