(there is only one common wire in the cable, two hot, and one ground),
with loose wires, it is possible you crossed the two 120v hot lines,
providing
the high voltage he suggests. I believe the whole problem
was caused by the poor connections, Don. Not sure how the ProSine
should react to 240v hitting it, but could well weld some contacts, as
you found.

2 hot spades into the socket and let only the third wire do the
ground, you will get a 250V zap. The 4th wire is the ground for the
other hot one. I don't know the details exactly, but whenever you let
2 hot and only 1 ground enter, you go BOOM. I know that you must have
all 4 wires, contacts, firmly connected before you turn the breakers on.

Black=hot
Red=Hot
White = Ground,
Bare wire = ground
These four must be in solid contact.
