Load bank tweak

I finally got around to a minor change with this load box. I originally had the temp sensor on the bottom. Admittedly, I didn't consider the effect of convection it was more of what was quick and convenient. The thermostat is an adjustable snap-disc (90- 120degF). The crawlspace hovers around ground water temperature most of the year, so when this thing is working not much heat hangs around the base.

I think this will be better, and it was simpler than I'd anticipated....

How much current is that snap-disc switching?

It's just the fan Spar, .1A @48V. I believe it is rated for 25A @125 VAC. The elements are switching (off Aux2, PWM) through a 75A Teledyne, 3-phase SS relay.
