What is Causing My Electric to Hum?

Have you ever had such a great day that when you are alone you begin humming or whistling a song you recently heard? That’s when you know that you are having a great day! But, unfortunately, hearing a hum coming from one of your electrical systems or outlets can ruin all that. Don’t let it!

Dimmer Lights
Did you know that when you use a dimmer switch, you are not actually dimming the energy. Instead it is being turned off and on so fast (many times per second) that our eyes don’t notice it. The hum from your switch could be caused by the constant switching of power on and off.

Outlets
If you tracked that hum down to one of your outlets, don’t ignore it! It could mean that a wire is no longer properly grounded or that too many volts are being carried over those wires. Give us a call to repair it!

Circuit Breakers
If you hear an electrical hum coming out of your circuit breaker box please contact us immediately. That could mean that your box is being overloaded with current, but is not shutting off properly the way it was intended.

If you wish to investigate the problem yourself, try shutting off the power entirely and then turning the breakers back on one at a time. This could narrow down the cause. We always recommend contacting a licensed electrician when dealing with the electrical safety in your home.
