Circuit breakers are an essential part of any home’s electrical system. These devices protect your home from electrical fires, power surges, and overloads by automatically cutting off the flow of electricity when a fault is detected. Understanding how they work and how to maintain them is crucial for ensuring the safety and efficiency of your home’s electrical system. With this in mind, we at Burley Electrical Services would like to discuss what you should know about circuit breakers for home electrical safety.
What are Circuit Breakers?
Circuit breakers are switches designed to interrupt the flow of electricity in a circuit when the electrical load exceeds safe limits. They prevent overheating and potential fires caused by excessive current. Installed in your home’s electrical panel, these devices control and protect individual circuits throughout your house.
How Do Circuit Breakers Work?
A circuit breaker is composed of a switch connected to either a bimetallic strip or an electromagnet. When the electrical current surpasses the breaker’s rated capacity, the strip bends or the electromagnet pulls the switch, opening the circuit and halting the flow of electricity. There are three primary types of circuit breakers:
1) Standard Breakers: These protect against overcurrent and short circuits.
2) Ground Fault Circuit Interrupters (GFCI): These protect against ground faults, which can occur when electrical current strays outside its intended path.
3) Arc Fault Circuit Interrupters (AFCI): These protect against arc faults, which can result from damaged or deteriorated wiring.
Signs of Circuit Breaker Issues
Knowing when your circuit breaker needs attention can prevent dangerous situations. Common warning signs include:
Frequent Tripping: If a breaker trips repeatedly, it may indicate an overloaded circuit or a more serious wiring problem.
Burning Smell or Scorch Marks: These are signs of overheating and potential fire hazards.
Breaker Won’t Reset: A breaker that refuses to reset may be defective or handling a persistent fault.
Humming or Buzzing Noise: These sounds can signal electrical arcing, which is a fire risk.
Circuit Breaker Safety Tips
1) Know Your Electrical Panel: Familiarize yourself with the location of your electrical panel and label each breaker to identify the circuits they control.
2) Avoid Overloading Circuits: Distribute electrical devices across multiple outlets and avoid running high-power appliances simultaneously on the same circuit.
3) Test GFCI and AFCI Breakers Regularly: Ensure these specialized breakers are functioning properly by pressing their test buttons monthly.
4) Schedule Inspections: Have a licensed electrician inspect your electrical panel every 5–10 years, especially if you live in an older home.
5) Replace Old Breakers: Outdated or damaged breakers should be replaced promptly to maintain safety.
When to Call a Professional Electrician
While some minor issues, like resetting a tripped breaker, can be addressed by homeowners, more complex problems require professional attention. If your breakers trip frequently or you notice any of the warning signs mentioned earlier, contact a licensed electrician to diagnose and resolve the issue.
