![]() Both breakers immediately trip when they detect a short or overload in a circuit.Īside from standard circuit breakers, you can also find these single and double-pole breaker designs in plug-on neutral circuit breakers. Nevertheless, despite their different capacities, these breakers have the same function: to keep any circuit in your home safe. You’ll need to install both breaker types in your electrical panel to run household appliances and lighter machines simultaneously. Double-pole breakers protect heavy machines, as they can provide 20 to 60 Ampereges and 240Volts.Single-pole breakers are typically used for low-power appliances, as they can provide 15 to 20 Ampereges and 120 Volts.Furthermore, this process can prevent overloads from damaging your circuits.ĭo you find the guide above helpful? Why don’t you share this article on social media so your friends can see this tutorial? It would also be beneficial to others if you shared your thoughts in the comment section. 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. Wire stripper for exposing the wire end.20-amp single pole circuit breaker for installing a new circuit.Non-contact voltage tester for checking the line for presence of electricity.Rubber gloves for additional protection.Plier and hammer for taking out the knockout cover.Set of screws for tightening and loosening the screws and terminals.
