Essential Information You Need to Know When Choosing a Circuit Breaker

If you are in the process of figuring out which circuit breaker is best for your needs, then you should first know more about it. It is very important that you do not commit a mistake in choosing the right circuit breaker since this is a crucial part of your safety.

Circuit breakers basically protect you from the hazardous effects of power overloading and faulty wiring systems. Through the use of circuit breakers, you can regulate the right amount of electric load in your building. If there is an excess power surge, the circuit breaker will “break” the power supply, rendering your building powerless and preventing further damage to your appliances and your building as a whole. When you have already addressed the problem that caused the circuit to break, then you can restart the electricity by just tripping back the circuit breaker panel.

In order for you to choose which circuit breaker is the right one for you, take note of the following information.

Types of circuit breakers

There are different types of Wadsworth circuit breakers and it all depends on the amount of your needed voltage. There are three basic categories that you might want to choose from. These are standard circuit breakers, GFCI (Ground Fault Circuit Interrupter) circuit breakers, and AFCI (Arc Fault Circuit Interrupter) circuit breakers. Get to know these types of circuit breakers and their recommended use.

If you intend to use the circuit breaker in your house, then only a low voltage electric current is needed. You can check the voltage capacity of a circuit breaker. Usually, a 110 or 220-volt circuit breaker is enough for household purposes. For larger buildings, you might need a voltage capacity as large as 72,000 volts.

Choosing the right circuit breaker

There are three factors that you need to consider when you choosing a circuit breaker. This may include mounting style, current rating, and voltage rating.

The mounting style is important to consider since this will affect its mode of installation. There are two common types of mounting styles. One is the DIN rail breaker and the other is the panel mount breaker.

Next is the current rating which determines how much electricity a circuit breaker can tolerate. Ampere is the unit used to measure the flow of electricity. Circuit breakers are calibrated to accommodate a specific range of ampere.

The third is the voltage rating. Voltage is the actual amount of electricity being distributed to your building. From power plants, the voltage is very large – and if it is directly delivered to your building, it will surely toast your appliances and start a fire. With the use of other devices such as a transformer, the voltage can be decreased so that it can be safely used by your building. Finally, the circuit breaker will regulate the voltage you need, usually 110 or 220 volts. It is important that the voltage rating of your circuit breaker will exceed the system voltage of your AC or DC.

This is just some of the basic information you need to know when choosing a circuit breaker. Remember to do further research if you are still unsure of your choices.
