I have a space in my garage near my washer and dryer where I would like
to place a treadmill. It is a '70's house with basement on one
circuit. Am afraid running washer/dryer and treadmill will blow
circuit breaker.

Dryer is Gas, but there is a 220v plug right there, and would
neccesarilly be on a seperate circuit (right??) Is there some sort of
transformer plug type thing that I can plug into 220 v circuit plug,
then plug 110v treadmill into that circuit.

I don't want to start running new circuits, which of course would be
the correct answer here, just looking for a safe temporary solution.
