Although the average homeowner will never need to choose, install or replace any of their own circuit breakers, understanding how to choose the right breaker for the job can increase your overall understanding of the way that your home’s electrical system works. Your circuit breakers are the first line of defense against dangerous levels of electrical current. They control how much electricity is allowed to flow through a particular electrical system. If you experience an electrical overload, a well-functioning circuit breaker will detect this overload and shut off electrical power so that your appliances and wires do not become damaged. In order for the circuit breaker to work properly, however, you must make sure that you have a breaker that matches your specific needs. This is something that your electrician in Glendale will be able to help you with.
Different Circuit Breaker Types
Each circuit breaker is designed to handle a specified amount of electricity. Most homes utilize low-voltage magnetic circuit breakers that only allow for electrical currents up to 1000 amps. Medium sized voltage circuit breakers can be found in large buildings and allow up to 72,000 volts. High-voltage circuit breakers are used in areas that use more than this frequently.
Choosing Breaker Size
You will need to first check the wire size printed on the cable that will be connecting to the circuit breaker. There will be two measurements. The first measurement will tell you the gauge of the wire and the next will tell you how many wires are inside the cable. The gauge of the wire will tell you the size of circuit breaker that you need: 8-gauge wire – 40amp breaker, 10-gauge wire – 30-amp breaker, 12-gauge wire – 20amp breaker, 14-gauge wire – 15-amp circuit breaker.
