A sliding ELECTRICAL POWER contact on aluminum??!!?? Yes,
boggles my mind, too!
Maybe it would work on a manually-controlled dimmer, but not
an automatically-adjusted one.
I told the guy who specced that transformer off explaining

his education.
Well, it probably wasn't Harris' fault, they bought an
off-the-shelf powerstat and expected Superior Electric knew
how to build them. Obviously, NOT!
