3 POLE 15 AMP BREAKER HOW TO

On the other hand, “pole” stands for how the breaker creates the electricity to distribute. “Phase” in this context indicates alternating current. The difference between a 3-pole and 3-phase circuit breaker generally lies in the terms used. What is the Difference Between a 3 Pole Vs 3-Phase Breaker? Certain 3-pole circuit breakers might not be compatible with this type of application. Hence, users should pay attention to the type of device they’re using in their service panels. But this breaker should be made to be used for single phase circuits that can use two poles. It’s possible to use a 3-pole circuit breaker for a 2-pole setup. Step 5: Turn on the main circuit breaker and test if the 3-pole breaker is functioning well.Ĭan a 3 Pole Breaker Be Used in a 2 Pole Application?.Step 4: Attach the two remaining wires to the circuit breaker and tighten them.Then, place and secure it in the ground service bar. Step 2: Find the three hot wires going into the panel and loosen their terminals with a screwdriver.Step 1: Turn off the main circuit breaker in the electrical service panel.But some differences exist with this 3-pole setup, particularly for a three-phase circuit.

How to Wire a 3-Pole BreakerĬonnecting wires to 3-pole circuit breakers is similar to forming single- or double-phase electrical frameworks. Plus, the typical 3-pole breaker has a 30-amp rating to fit NF service panels. As you can see, these voltage ratings are reasonably high, providing sufficient and balanced power output to different motors and other pieces of equipment.įor example, a 3 pole 240v breaker would be the ideal choice for numerous applications, such as transformers. How Many Volts in a 3- Pole Breaker?ģ-pole circuit breakers often have varying ratings, such as 240V, 380V, and 400V. How Many Wires Can Be in a 3 Pole Breaker?Īs its name implies, the typical wiring diagram of a 3-pole circuit breaker uses three live wires.

However, the higher amperage and voltage capacity from the number of conductors makes it an excellent choice to use in a three-phase electrical setup.Ī usage example of an arrangement that uses a 3-pole breaker is to connect this unit to a water heater, air compressor, or air conditioner. If this circuit breaker receives a higher electrical current than its capacity, it’ll trip and prevent damage to the connected equipment. How Does a 3 Pole Breaker Work?Ī 3 poles circuit breaker typically works like a standard breaker. The higher voltage rating capacity offered by the 3-pole circuit breaker makes it ideal to use in commercial and industrial facilities. In comparison, a single-pole breaker will often only supply about 120VAC for three-wire terminals and 240VAC for two hot wires.

As its name implies, it uses three wires for power delivery through three separate switches. What Does 3-Pole Mean on a Circuit Breaker?Ī three pole breaker typically supplies 480 Volts of Alternating Current (VAC) to connected devices or equipment.
