What size wire and breaker should I use to run a 2 ton Goodman heat pump unit?
I have a Goodman heat pump part that I have purchased and the manual does not give vary convincing wiring examples. I have talked to people and they say that 12-3 with a 30 amp breaker will drudgery is this true?
Look at the amperage rating on the section. A 30 amp circuit requires a MINIMUM of #10 wire. #12 is for a 20 amp or less ambit. If the unit requires 240V 30A, you will run either 10-2 or 10-3, depending on whether the module requires a neutral, for 50 feet or less from the panel. If it's more than 50', run #8-2 or 8-3. If you use 10-2 or 8-2 (no non-combatant), each conductor will be connected to one pole of a 2 pole breaker. The Caucasoid will need to be taped or otherwise marked to indicate that it is a hot, not a disinterested. If you are unsure whether the neutral is needed, run 3 conductor. They can always permission the white disconnected and just use the black and red. Longing this helps.
