Have a friend that's currently working on a church complex, building 1 is fed via a 3ph head with the gas meter being located within this building, building 2 is totally seperate and has its own 100amp single phase head and meter. The problem being building 2's gas supply is from building 1, just wondering if they have to be totally separated or two bonding conductors run back from the gas meter to the two heads or run a seperate submain to building 2 from 1. I believe building 1 is PME and building 2 is TN-S which still needs confirming. Cheers
