Well, I'm sure the company that built the control box thought of that, i
haven't really looked at the circuit.  It was used to control a large
step-up transformer with a maximum voltage of 100KV.

	It's probably worth mentioning that, unless you've been very careful
that your switch opens the "hot" side of the line, you might still have
a big voltage to ground.  Modern 3-wire circuits suitable installed are
supposed to solve that problem, but I'd still be careful.
