That is the first panel hole I made on the HB 3CX1000A7 1500W 2M amp almost 30 years ago and duplicated later on the 8877 222, and GL-51064 432 MHz amps.

Breakers, 240V contactors, and step start at those power levels are mandatory in HB IMO. Also reasonably idiot proof for my senile citizen years....

I always liked the front panel circuit breaker on commercial equipment that is a sure fire way to remove all power in the instrument, except the line going to
the breaker from the external power cord.

"That's a good point. The answer IMO is to do the variac ramp up quickly,
say in about two seconds or so. That should give you time to watch the
line current and HV."

Or, simply jumper-bypass the step/start resistors during testing, as the
Variac is performing that function anyway.
