The problem is that the customer see's if one phase goes down the other
phase SHOULD keep the system going

Very rarely will you lose only one phase. And if one phase is lost a
switching device will feed from another phase? This sounds a little
extravagant for the very few times it would be used. The conventional setup
is a UPS (for power filtering and short outages) and a generator (for long
outages).

the UPS people have hinted that
the one phase may not support the 32amp max that the FULLY loaded cab

could
demand.

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

Thanks for that Larry,

I'm sure I read a document that covers the safety angle.

Cubzilla,
I'd only use one phase for the entire cabinet for simplicity sake.

There's no reason to endanger anyone by trying to power this unit with

phase
A, and that unit with phase B. :-(

Hiya all

We are trying to install a 10K series Compaq/Hp cabinet to support an
EVA5000 the cab has 2 PDU's is it ok to feed the 2 PDU's from separate
phases or will this be a health & safety issue ie the potential

difference
across the 2 phases could reach 480 volts.


any URL's to the info would be appreciated.


Regards Trevor
