[QUOTE="Revved Up Sparky, post: 288171, member: 5050"] Why does BS7671 state that we need to bond incoming services to the MET?. Those services are capable of introducing a different earth potential to the property than that earth potential which exists at the MET of the electrical installation, therefore an equipotential zone is required where there are no potential differences. Therefore the second gas pipe entry point is not going to introduce a different earth potential so IMHO it does not need bonding to the MET. [/QUOTE]
