I have a building that is powered from an outside transformer. The building will also be backed up by a generator, for all power, via a 4 pole transfer switch. The transformer, generator and transfer switch are located outdoors. Questions, 1) will the transfer switch require OCPD for the transformer feed into it & 2) where should the N-G bond take place, at the transfer switch or inside at the Main switch in the switchboard. Thank you in adavnce for your responses.
