   A lot of switches and breakers are rated for A/C; the
D/C current capacity is almost always significantly lower
than the A/C rating.  It is good practice to "short" a
circuit via a wire-wound high-wattage resistor, say,
10 Ohms / 50 watts.  Nevertheless, I'd call a breaker
defective if it burned up on a single shorting - that's
what a *fuse* is supposed to do.   ;^)
