Though the video is short, he discusses all the basic information about the two circuit breaker types. This video by Circuit Breaker Wholesale will also give you a better understanding of the single pole and double pole breakers. This double pole breaker with one switch also has the same function and features as the standard double pole breakers If you notice a double pole circuit breaker that only has one switch, that’s because its bridge connection is already inside the circuit breaker body, hidden from view. The bridging switch of the breaker holds a great feature that protects the whole circuit.įor example, if one side of the breaker trips, the other half of the double pole breaker will also trip promptly to safeguard your circuit. Each terminal of a double breaker is protected by half of the breaker. It indicates that the 2 pole breaker generates 240 volts of power by combining two single circuit breakers. It is also rated 20 to 60 amps and primarily has a 240-volt single circuit service to power most electrical outlets for your high-power appliances like air conditioners, electric ranges, hairdryers, and more. It has a bridge switch and consists of two hot buses and one neutral wire as the third wire for its wiring system. What Is a Double Pole Breaker?ĭouble pole circuit breakers are breakers that occupy two single pole breakers slots. It can be used for some lower voltage circuits to power small appliances rated 120 or 110 volts but not for a higher voltage like 220 volts hair dryers. Furthermore, it can also be installed in a standard outlet with a two-slot outlet receptacle. This breaker is rated 15 to 20 amps for a single circuit that provides 120 volts of power service.Ī single pole breaker is mainly used for the general lighting circuit of houses. It has one switch and only needs to connect two wires, one for the hot bus bar and one neutral wire. Generally, a single pole circuit breaker is a type of breaker that has a size that fits in one slot of your panel. You may not find some of this in a home electrical circuit as it is primarily used in an industrial installation with higher line voltage. These breakers, including TP, TPN, and 4P, have different features and functions. There are three pole breakers, triple pole and neutral, and four poles. There are other types of circuit breakers that have more than two poles. On the other hand, the AFCI breaker detects an arc fault like overheated wiring and short circuit that may fire and damage your property. This feature protects against electrical shock or electrocution. The GFCI breaker is designed to immediately cut the electricity of the circuit when it detects a ground fault. However, these breakers are slightly different from the standard breaker and plug on a neutral breaker due to their pigtail wire connecting to the ground bus bar. These breakers have advanced features that help your circuit be much safer. If the standard circuit breaker uses one neutral wire that you need to connect to the bus bars, the plug on neutral breaker does not use a single neutral wire.Īside from the single neutral wire connection, a plug on the neutral breaker has easy clip features to connect the neutral link directly to the bus bars.Īdditionally, there are also called Ground Fault Circuit Interrupter (GFCI) and Arc Fault Circuit Interrupter (AFCI) for single-pole and double pole circuit breakers. Both standard and plug on neutral breakers use a single hot wire for single-pole and two hot wires connected for double pole breakers, but they have different neutral installations. 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.
