I have an existing warehouse with five mains. The distribution wiring was stolen and I am preparing drawings to replace it. Three of the existing mains have a neutral wire coming from the utility company (ungrounded service). Two of the mains have no neutral and these main disconnects also have no neutral bar. Service is 120/208V-3 phase (or possibly 240V hi-leg - haven't been able to confirm although all three phase conductors are the same size).
1. Is it acceptable to splice the neutral from one main with a polaris and use it as the netural for the two services without a neutral? This appears to be how it was done before.
2. Building department is requesting that the building ground be ugpraded. Without a neutral bus at the main, how can the service be grounded?
