I've also used the Sears current-sensing unit,
but I found it requires a fairly heavy load to
trigger it (as it's made for power tools), and
a preamp alone isn't enough.
Ah. That is what you had mentioned and I got confuzzed again. One could always plug their spa heater into the preamp's switched power output.
