A circuit breaker is a central component of modern electrical systems. This important safety device puts a limit on the amount of power moving through your home’s circuits to prevent overloads that could cause damage to your electrical system or even start a fire. Knowing what your circuit breaker does and where to find it are two basic pieces of information every homeowner should have. If you have questions about your home’s electrical system, can’t find your circuit breaker, or need any type of electrical repair or upgrade in Fairfax or Montgomery County, contact your residential electrician for the help you need.
