Hello Jonathan,

My heavy variac is in a cage with a base plate that either sits on the bench
or is bolted to a panel.  The center shaft must be moved and the knob
mounted on the other end of the shaft for panel mounting.  Thus, to increase
the voltage as the knob turns clockwise, the wiring must differ because on
the panel, the wiper is turning the opposite direction from the direction it
turning on the bench.  (I hope that makes sense.)

Regards,

Pete Komen

Hi All,

I have 2 questions about hooking up my variacs.

1) What is the difference between panel and bench mounting? The variac
diagram
shows using different input and output terminals depending on whether it is
panel or bench mounted. What's up with that?

2) No matter what terminals I end up using, the capacitor for the variac
should
be connected across the mains, right?

Thanks again again,

Jonathan Peakall
