I had a discussion just the other day with my coworkers about the 3-phase AC used on aircraft and about how there are two additional wires in the cable that carry a deadman signal. If you unplug the plane while the generator's still built up, the deadman opens the contactor so you don't get fried. But there's an override switch, and stupid people doing stupid things have killed themselves.You must be registered for see images attach
We used to charge $5/scrape and $10/cut when working on vehicles. That was back in the 70s, I'll bet the price has gone up since then!I cut my middle knuckle on my left hand first thing this morning.
