Dave: Whoops! You are correct. I was
confusing it with the XPS3, which is a
120V/20A switch (though it doesn’t say how
many HP it will handle but it is probably
1HP). Unfortunately the XPS3 responds to
AllLightsOn, which could be a problem for Gene.
Another option might be the XPR, which, like
the XPS3, is rated for 120V/20A but it
doesn't respond to AllLightsOn. Or there are
the ACT RS101, RS114 and RB104, which are
rated for 20A/1HP at 120VAC (the RB104 is
actually rated for 30A resistive and can work
with either 120 or 240VAC).
