Rich,

Yes, it sure will and is what it's designed to do. Another member on here and myself done some investagating on surge currents and it was surprising about how many cycles it takes for a transformer to completely level out (about 20-25 if I remember on the one test). The first few cycles (about six) was really when it drew the most and were talking a HUGE amount. Richard Measures was looking at one a while back, and it came up to over 100 amperes at startup.

I am building my first amp , now starting on the power supply. It will
have a 240v 10 amp Powerstat. I have a 4 pole "latching" relay that I
think I will wire so it has a safety drop out , then a DPDT relay with
my soft start resistors. The last variac that I set up to control
voltage for a tesla coil always caused a problem when I plugged it in.
It would blow to 20 amp circuit breaker even though the system pulled
less than an amp at idle.  I would have to try several times to get it
to stay on line. The only thing wired in was the variac and a 24v
control transformer.
I am hoping to avoid any problems with the HV system as I build it, will
the soft start system take care of the instantaneous inductive load that
it appears I was getting with my other variac ?
