Double Pole Breaker For Two Circuits. Then a hot comes off each terminal of that outlet to feed two 110 v circuits. Why the two runs of 12 2 into the other receptacles.
Each of these connects to a terminal on the breaker and is protected by half of the breaker. Double pole breakers snap onto two poles for a total of 240 volts. 35 00 previous price 35 00.
Why would 14 3 and a double breaker be used instead of just 14 2 and single pole breakers.
The neutral does not remain hot but what the double pole breaker does is make sure the current from the other leg of the multiwire circuit also stops flowing through the neutral otherwise you could disconnect the neutral and have a lot of current flowing through it making for one large arc and resulting affects which could include fire electrical shock etc. Square d qo 20 amps tandem. I found that the wire that runs the bathroom is a 12 3 ground wire on a 30 amp 240v double pole breaker. I pulled the 240v breaker and put in two 120v 20 amp breakers to see what all is on the circuit with the bathroom.
