I got a call today customer had no power on one side of the house & hot water heater doesn't work. I head over and find a NIGHTMARE!!!! The hot water heater was a 220 but was run with a red, black, & ground (no neutral)! The lights I hope to be a breaker. I now have to rewire the hot water heater & oven that had caught fire ( it was run the same way!) This was my first service call being on my own and it was a nightmare! I guess it was much needed experience! I will post pics Saturday when I go back to finish up!
