" Very rarely will you lose only one phase. And if one phase is lost a
switching device will feed from another phase?

The equipment in the cab ALL have dual power supplies that receive power
simultaneously. The supplies are connected to both of the PDU's if half the
power fails the supply to the other half is already there and the kit can
function correctly (from one PDU).


Then run 3 phase power into the cabinet. Just make sure all wiring is
clearly labeled.

The kit (PDU's) have a single phase cables coming out of them the cab is not
designed for 3 phase, the "tails" from the PDU go under the floor to the
power distribution from the UPS

Thanks anyway Larry
