-------------------------------------- That's a legitimate concern with our present 13.8 supplies as well. Twenty or thirty amps can be very dangerous if you get a piece of jewelry across the contacts. If you're unlucky enough to fail to make good enough contact to trip the crowbar or blow a fuse, you'll be frozen there as the ring (or bracelet) melts into your flesh. Almost everyone who has worked around aircraft knows someone missing a ring finger and sometimes a whole hand from just such mishaps. Working on a fighter one night at Lockheed Aircraft, I heard a power cart groan and looked at the next plane sitting wingtip to wingtip with the one I was in and saw smoke billowing from a partially-opened canopy and a tech unconscious inside. It turned out he had tried to replace a breaker without disconnecting power and dropped this screwdriver where it contacted the power bus bar and the side of the airplane. The metal shaft of the screwdriver literally exploded into globules of molten metal that caused him to jump up, smash his the back of his head on the canopy and knocked himself out. Other than a concussion he wasn't seriously hurt but the plane was a mess. That's one very good reason to be sure that 20 amp fuse Elecraft specifies for the K2/100 is in the power line.
