As another poster mentioned there are potential shock
problems. If you popped a circuit breaker, chances are only
one would pop and the other leg would remain hot.

You pays your money and you takes your chances.

The 220 breakers are dual, and break the entire circuit. But you have to assume by the site that
the box attempts to prevent that.

Bottom line is this unit is for people afraid to open their circuit box and do the job right.
