According to Grant Erwin :

Many
people have told me that the wall voltage must be wired to the slider, but it
can't be and isn't.

Grant,

I'm sorry, but in *none* of the followups in this thread have I
seen anyone saying that the wall power should be connected to the wiper.

I have seen *many* (and I am among those) who said that the wall
power must *not* be connected to the wiper. Could you go back through
and find the ones which suggest connecting the wall power to the wiper?

There have been some who asked whether the wall power *was*
connected to the wiper, as that is the most logical reason for the
breaker popping at low settings but not at high settings -- at least
before you came back and said that once the power was turned on you
could go through the full range with no subsequent popping of the
breaker.

Good Luck,
DoN.
