BLOG Circuit Breakers Explained: Expert Advice from Nominal Voltage Electricians Jul 17, 2024

Circuit breakers are one of the most important components of any electrical system. They act as the first line of defense in case of an electrical overload or short circuit, helping to protect your home or business from potential damage or fire. As electricians at Nominal Voltage, we understand the importance of circuit breakers, and we're here to provide expert advice on how they work and how to maintain them.

First and foremost, let's start with a basic understanding of what circuit breakers are. A circuit breaker is a switch that automatically interrupts the flow of electricity in a circuit when it detects a fault. This could be an overload - when too many appliances are operating on the same circuit - or a short circuit - when there is a fault in the wiring causing a surge of electricity. When the circuit breaker trips, it cuts off the electricity to prevent further damage.

There are a few different types of circuit breakers commonly found in residential and commercial buildings. The most common type is the standard breaker, which is designed to handle loads up to 20 amps. These are typically used for outlets and lighting circuits. Another common type is the GFCI (Ground Fault Circuit Interrupter) breaker, which is designed to protect against electrical shock in wet areas like bathrooms and kitchens. AFCI (Arc Fault Circuit Interrupter) breakers are another type that protect against electrical fires caused by arcing. It's important to have the right type of circuit breaker installed in the appropriate locations to ensure maximum protection.

Now that you know the basics of circuit breakers, let's talk about how to maintain them. One of the most important things you can do to ensure your circuit breakers are working properly is to regularly test them. This involves flipping the breaker to the off position and then back on to see if it trips. If it doesn't trip, it's working correctly. If it does trip, you may have an issue that needs to be addressed by a professional electrician. Additionally, it's important to keep your circuit breaker panel clean and free of dust or debris, as this can cause overheating and potentially lead to a fire.
