Keep in mind that the the difference between single pole and two poles normal circuit breakers and a GFCI is that there is a builtin white wire on the back side of GFCI and it must be connected to the neutral busbar in the mains supply or it will not work and protect the circuit properly. By Krystal M Updated: December 29, 2022 Any circuit supplying either 120/240 volts (with two hot wires and one neutral wire) or pure 240 volts (two hot wires) is required to be GFCI protected by the National Electrical Code (NEC). But, how to wire a 2 pole GFCI breaker without neutral?
2 Pole Gfci Breaker Wiring Diagram
A 2 pole GFCI (Ground Fault Circuit Interrupter) breaker is a type of electrical breaker that provides protection against electrical shocks. It is designed to quickly detect and interrupt ground faults, which occur when an electrical current flows through a path other than the intended circuit. This instruction sheet contains installation, wiring, testing, and removal information for two-pole (2P) QO/QOB Circuit breakers and Ground Fault. Outline of the Steps The procedure involves the following five steps: Turning off the main panel breaker Testing for power (to ensure it's off) Identifying the GFCI breaker Wiring it (the main part) Two-pole GFCI circuit breakers are also available to control two circuits simultaneously. RELATED Wiring a GFCI Circuit Breaker The procedure for wiring a GFCI breaker is similar to how you would attach a regular circuit breaker, except it comes with an extra white wire, typically coiled or pigtailed.

The Siemens 2-pole GFCI circuit breaker can be installed on a 120/240V AC single phase, 3 wire system, the 120/240V AC portion of a 240/120 volt, 3 phase, 4 wire system, or on a 208Y/120 volt, 3 phase, 4 wire system. When installed on these systems, protection is provided for 2 wire, 240V AC or 208V AC circuits; 3 wire, 120/240V AC circuits. The two "hots" that share the neutral must be landed on a 2-pole breaker. This 2-pole breaker assures common maintenance shutoff (an MWBC rule) and that the hots are on opposite 120V poles (a very absolute MWBC rule). Protect a shared-neutral with a 2-pole GFCI breaker. As it happens, they make 2-pole GFCI+breakers, which accept 2 hots and a. ( See Diagram A ). Replace the receptacle, screw it back into the box, and attach the cover plate. Turn the power back on at the circuit-breaker panel. Plug a clock radio or light into the outlet. Test the GFCI by pressing the Black "Test" button on the outlet.

Delmarva, USA. Nov 15, 2009. #6. Square D 2-pole GFI breakers only have a neutral load connection on 50 Amp and smaller units. Their 60 Amp breaker is for 240 Volt loads only. As you have discovered, there are no operational problems with this configuration on 240 Volt loads. 2. Turn "ON" the AFCI/GFCI handle. 3. Press blue test button (F) as shown in Fig.1. The AFCI/GFCI breaker is functioning properly when: 1. The circuit is interrupted. 2. The handle moves to the tripped center position (G) as shown in Fig.1. LEDs (J,M) are used to indicate the last know trip condition. Note: Test every month TROUBLESHOOTING
This circuit breaker wiring diagram illustrates installing a 20 amp circuit breaker for a 240 volt circuit. The 12/2 gauge cable for this circuit includes 2 conductors and 1 ground. The white wire is used for hot in this circuit and it is marked with black tape on both ends to identify it as such. A neutral wire is not used in this circuit. 21 1 3 Add a comment 2 Answers Sorted by: 1 No, you do not need a neutral "load" wire if you're running only 240V load. The GFCI will detect any imbalance between the two phases and trip if one occurs. See picture below. The green wire can never be used for anything but a ground.

Double Pole Breaker Wiring
Press the "Test" button on the breaker, and it should trip, cutting off power to the circuit. Press the "Reset" button to restore power. If the GFCI breaker doesn't trip when the "Test" button is pressed, double-check the wiring and consult the breaker's installation instructions. Pierre. is not the white (neutral) conductor that is connected to the 2 pole GFCI breaker necessary for the breaker circuitry to operate properly. The neutral pigtail is not for the operation of the breaker as the GFCI circuit does not need a referance to ground. if there was 120 volts being used then yes as the neutral would have to be.
