Re: IS 240VAC two-phase - NO



Original poster: dhmccauley-at-spacecatlighting-dot-com 


240VAC is correctly denoted as SPLIT single phase.  It is NOT two phase.

It is simply a centertapped, 240VAC single phase line from a single phase
transformer.

Two phase denotes a phase angle difference of 180 degrees. The sum of all
phases in any system must always equal 360 degrees. The standard home
electrical system in the US is two phase, 180 degree difference( two times
180 equals 360). Each phase is 125 volts RMS to neutral, and 250 volts RMS
from phase to phase.
