In Europe and Australia, the same thing is known as RCD “Residual Current Interrupter” or RCCB “ Residual Current Circuit Breaker” or if overcurrent protection device such as MCB is used with combination of RCD i.e. In America, it is commonly known as GFCI “ Ground Fault Circuit Interrupter” or “ GFI “ Ground Fault Interrupter” or ALCI “ Appliance Leakage Current Interrupter“. RCCB is also known as “ Residual Current Circuit Breaker“.RCD is the short form of “ Residual Current Device“.GFCI is the abbreviation of “ Ground Fault Circuit Interrupter“.Wiring a Four Poles RCBO or GFCI Circuit Breaker (Three Phase RCCB Wiring).Wiring a Three Poles GFCI Circuit Breaker.Wiring a Two Poles GFCI Circuit Breaker.

Learning how to install a single pole 20 amp breaker is an easy process that can be done, even if you aren’t someone specializing in the electrical field. This circuit breaker is mainly used for high-powered devices and equipment that require a dedicated circuit.įind out in detail the difference between single pole and double pole here. On the other hand, a double-pole circuit breaker is a circuit with a 240-volt power source. It is primarily used in various lighting systems as well as typical household appliances. What Is the Difference Between Single-Pole and Double-Pole Circuit Breakers?Ī single-pole circuit breaker refers to a single circuit with only a 120 volts power supply.

It would also be helpful if you watched this video by Dan Jiles to see how the process can be done correctly. This way, you can avoid a power surge when electricity is suddenly turned on.

Turn on the main breaker and then turn on your new circuit breaker. Tips: When turning on the power supply of your breaker, start from the main switch. After that, close the cover and activate all of your circuit breakers. Make sure that there is no pinched wire when you put back the cover panel. Put Back the Panel Coverīefore putting back the cover panel, ensure that all the wires are properly aligned to keep them organized. The circuit breaker can now be snagged to the panel board. Measure the length of the cable up to the circuit where the breaker will be installed.Ĭonnect the wire end to the circuit breaker terminal after stripping it. If you use a 10 gauge wire, consider choosing a 30 amp breaker. Since this circuit is only using a 12-gauge wire, you can start wiring a 20 amp breaker and the hot wire first before installing it into the panel. Using your side cutter, cut the ground wire with the length up to the ground bar and connect it.įor the neutral wire, measure the needed length for the neutral bar, cut it, strip the wire end, and connect it to the neutral bar. Remove the wire jackets to expose the wires. You will only need to connect the neutral and ground wires in this process. The ground is copper or green, the neutral is white, and the hot wire is black. Connect the Ground and Neutral WiresĪs you can see when you search a single pole circuit breaker wiring diagram, you will see three wires. You can now insert the wire to the strain relief and lock the clamp using your screwdriver. Next, remove one knockout cover with your pliers where your wire needs to be inserted.

Unscrew all four edges of the panel cover with your screwdriver while holding it tight to prevent it from slipping off. Now, here is the circuit breaker installation guide for adding a new 20 amp single-pole circuit breaker to your circuit. To avoid electrocution, always remember to turn off the main breaker and use rubber gloves. You can research a 20 amp breaker wiring diagram online if you need a reference for the electrical wiring. Step-By-Step Guide of How to Install a 20 Amp Single-Pole Circuit Breaker Strain relief is useful for protecting your cable from the knockout hole’s metal edges.Īny strain relief can be used, but the metal kind with a wire lock is preferred as it is very secure. If you’re not using a conduit for your circuit, you’ll definitely need strain relief tools.
