Deriving Neutral - 08/07/06 06:40 PM
My question is regarding a 3-phase delta maint bypass circuit seemingly feeding a 3-phase wye panel in Italy. In the US, it would be illegal to do anything but bring the bypass neutral directly from the switchboard- does IEC (or any other european code) allow deriving the neutral at the branch panel or an arbitrary mid-point of the circuit? (No transformers, it's straight-through.)
Could it possibly actually be wired up this way, or do I need to beat up my eyes and ears for giving my bunk information, and try to get my boss to pay me to fly out to Europe again?
