Most people hear about these urban myths that if you balance your breaker box then you can save all this money. I know enough about electricity and enough electricians to know this is false. My question is a little different. I have a 100 amp breaker in my box that has never been on on my life. It is for the old electric furnace. I am an HVAC installer so I am putting a new furnace in my house. The furnace calls for 15 amp breaker/14-2 wire. The new A/C calls for a 40 amp breaker, no specification it needs to be double or single pole. I’ve seen electricians do both. When I pull that 100 amp breaker out of the box, what should I do? Just replace that breaker with a double pole 40 amp since it was obviously ran as a double pole? Are their any other options? Is it dangerous to pull a 100 amp out of the middle of the box and only replace it with a 40 amp? I’m very skilled technically and with a lot of things. I can use a multimeter and figure out open neutrals and grounds and such. I just don’t have much experience with actual breaker boxes and if there needs to be a code followed for this. Also I have multiple breakers that are no longer being used. Not sure what to do with those either. For the short term I can wire my furnace up with a nice extension cord and plug it in if I have to since winter is coming lol.
