The acutal rating is, I believe, 17% over the input line voltage
when the variac is wired for over-voltage use. You are correct in
that the terminals are numbered 1 - 5. In "overvoltage" mode the
variac is wired with #1 common to both input and output. Terminal
#2 is used for the second input. Terminal #3 is the second output
(wiper brush). Terminals #4 and #5 are not used.

Good question. Personally I feel the 15KVAC rms/pulse Condenser
Products capacitor could take it; but if it were mine I would not
risk it unless I was sure that other factors (voltage drop from
current limiting) were bringing the actual HV feed voltage back
to around 15 KVAC.
