So I get a call. The range at a rental house takes an hour to heat up. I look for a 2pole breaker. Don't find one in the outside service. I see a 100a breaker in it and figure it feeds a subpanel. I look no subpanel. I find a panel that feeds the a/c units and heat. So I go back to the service take the cover off and see #6 al with a piece of #14 wirenutted to it going to a 15a breaker. I'm sure they had a gas range at one time and converted it to a 120V circuit. I used a CU/AL split bolt to extend the wire they cut short. Guy said he had lived there 3 years with it that way.
Thought the range was bad. Goes to show you never know what you will find on a service call.:laughing:
