Nah, 240 is usually a delta system, unless its got one
side center tapped for 120. Then you'd have three
hots and a ground, and watch out for the wild leg, it
could also be an open delta. If its a wye system then
you'd have five terminals, three hots, one neutral,
and a ground, more likely to be 277/480 volts or
120/208.

This won't happen unless he did his own wiring. Which
scares me, but then you should see some of the crap
I've torn out of peoples houses and businesses. Most
houses don't have three phase anyway, only the really
big ones that the rich people own.

I've made the guys who walk on the high iron nervous.
They tell me I'm crazy to put my hands in those hot
panels.
You gonna take this to a real electrician yet?
