Miscellaneous Electric Tips

Switched ground is very very bad, dangerous, and beyond irresponsible. Never trust wire color. Always verify. Some memorable shocks of mine: Moving the bx line of a pump away from a wet hazard. The jacket cut into the hot and I convulsed and locked on. Lucky me, I was standing on a steep incline, and was able to fall away. This altered my heart rhythm. After some months of following a different heartbeat, I was working on something that had the tell tale switched ground. Not paying enough attention, I backhanded it, and my went flying in the opposite direction. That set my heart straight again, but with some shoulder pain, and we never did find the screws that had been in that hand. The absolute worst, was getting the pulsed 10,000 volts intended for an oil burner ignition. On that occasion I quickly took my pulse to verify that I was still alive, because standing up was just not convincing enough.
