When it comes to a commercial electrical system, the circuit breakers play a major role. The circuit breakers provide the electricity that flows through each circuit. As a major component to the electrical system, there is a lot that can go wrong with the circuit breakers. As the circuit breakers develop different problems, managers and business owners often have a lot of questions. Misso Electric will share some of the most frequently asked questions about circuit breakers and when to seek professional electrical services.
Is it Normal for a Circuit Breaker to Buzz?
A circuit breaker may make a very soft buzzing sound when it is on or electricity is passing through it. You may even hear a sudden but brief buzzing noise when the breaker is first turned on. This is because the rush of electricity has suddenly run through the breaker. However, if the breaker has been buzzing for a long period of time and buzzing appears to be getting worse and or louder, you will want to have the breaker panel inspected by a licensed electrician.
Can Rain Cause a Breaker to Trip?
During periods of rain the exterior or external outlets, extension cords or light fixtures can become wet. This will cause the breakers to trip. However, even a business premises’ exterior electrical system should not be coming in contact with rain. If the breakers are tripping every time it rains, you have an exposed electrical component that needs to be located and the problem resolved. Moisture that is exposed to the electrical system always poses a threat and it is one that needs to be addressed. Consider having your electrical system inspected by a licensed electrician.
Should a Breaker Be Warm to the Touch?
If you discover your breaker feels warm, this is not a good thing. When a circuit breaker becomes warm it indicates that there is too much electricity being used. Breakers are designed to handle a certain amount of electricity. Too much can result in fire. A breaker can also become too hot when there is a loose wire or the breaker is failing. Again, have your electrical panel and breakers inspected by a professional electrician. They can help determine why the breakers are becoming hot and repair the problem.
Why is there Still Power if the Breaker is Off?
If you switch the breakers to the off position only to discover the power is still on, this is a major concern. There is a metal clip or spring that contacts another metal piece that acts as a bridge for electricity to flow through. If that spring is stuck, then you will have a constant flow of electricity. If a breaker fails to trip or too much electricity flows through the circuit, it can and often does, lead to a fire. If a breaker fails to turn off, this is often considered an emergency and you will want an electrician to replace the breakers.
