Steve,

See the Staco web page for the overload graph. Most of their models will
easily do 250% for durations sufficient for coiling activities. The General
Radio specs should be comparable...

Hi Steve,
    The variac can do rated output at any voltage. If fact, you can overload
it to 200% for short times and not hurt it. I routinely use my 10 amp.
variac at 25 amps. After it finally gets hot, I just let it cool off. Your
w50 is a good one.
												Later,
												   James

Can anyone clear up some confusion about my General Radio W50 variac with
which
I am building my TC. The unit is 240 volts input and either 0 to 240 or 0 to
280 volts output. The current rating for the unit is stamped as 25 amps.
Does
the 25 amp maximum apply to the full 280 volt output or only at the 240 volt
output? Since I don't have access to a General Radio spec sheet, I am hoping
that someone on the list will know.
