 We had an 8530 that needed 3-phase.  I had to install the plug on the
 panel for our AC because our machine-panel only had two legs (everything
 we had was single-phase 120VAC except the TU78 - 220V).  Our AC was
 large enough that it had a 3-phase compressor. 
The 8530 don't *nned* 3-phase to run. It's normally equipped with a 
3-phase connector, but it can be converted.

The machine Robert is thinking of is the 86x0 machine, which have 3-phase
motors in the fans.
