To Gnarlodious,

Your discussion of three-phase electric motors (far beyond my knowledge)
rings authoratitive.

I don't mind "Two-Phase" for a 240V (two leg) but I have never seen that on
any electrical equipment. I've worked on many motion picture diesel
generators (mostly Crawfords) and they all have two settings:

240V single phase (four wire system)
208V three phase ( five wire system)

A switch throws from one output to another.

Same for electrical panels. Siemens, Murray and most every residential load
center is marked single-phase if it has two hot lugs and two bus bars
producing 240 volts between legs. Pretty much everyone I ever worked with
called that single-phase. Even the Los Angeles Dept of water and power uses
this term for a two-conductor, 240V service.

Reminds me of the discussion I got into about grounding vs. bonding...

vinnie
