This means that the combination of 2 single pole type CH breakers and a handle tie is only usable for 240V only or 120V only circuits as per NEC 24015B1 and 24015B2. If 3 wire romex is used as a branch circuit to supply two 120V circuits Black Red and White wire a two pole breaker must be used so all ungrounded wires in the multi wire branch circuit are disconnected simultaneously. For some reason Ive been finding a lot of 120V circuits fed from one pole of a two pole breaker.
When single-pole breakers are installed they snap into one pole to receive 120 volts.
Each of these connects to a terminal on the breaker and is protected by half of the. The neutral can be shared because it ties back to the center of the transformer coil while the hot wires go back to the two poles of the transformer coil and are indeed 180 deg out of phase with each other. There is no prohibition against connecting one 120 volt circuit to a double pole internal trip breaker nor is there a prohibition against connecting two 120 volt circuits to an internal trip double pole breaker. Although I would run a 120240 volt feeder you could run a 120 volt feeder protected by a 50 amp single pole breaker. 120V Switch Off and 240V we may use double pole DPDT switch. There is no single-pole 30A GFCI available that fits my panel 30A is an enormous capacity for a single-leg 120V circuit.
