If you hear a faint buzzing noise in your home, it’s easy to chalk it up to noises coming from a fan or an electronic device left on. However, you might want to take a closer listen – it could be coming from your electrical outlet. While an outlet making noise might seem like a minor issue, it could be a sign of a larger issue that could cause serious harm to your home. Our electrical experts are here to explain what you need to know if you hear an electrical hum noise in your home.
Did You Know?
Homes over 30 years old are more likely to have outdated wiring, increasing the risk of electrical issues. Regular inspections can help keep your home safe!
What Does a Buzzing Electrical Outlet Mean?
An outlet issue is never something to take lightly. Your home’s electricity is created by alternating currents, which change polarity nearly 50 times per second. Most of the time, the changeover produces no noise. However, when the current is interrupted, you might hear a humming or buzzing sound – also known as an electrical hum noise.
What Causes an Outlet to Make Noise?
Outlets are designed to operate silently. However, if you hear the hum noise, it’s often due to an issue with the current. Here are the most common causes:
Loose Connections
The number one reason for buzzing outlets is loose wiring, which is often found in older homes. If your home is over 30 years old, ensure you receive an inspection for safety and functionality.
Breaker Issues
If you hear a humming sound that's louder than usual, it could indicate an electrical imbalance, as it may be sending too little or too much power. Therefore, hire an electrician to investigate the issue and make necessary repairs.
Improper Installation
Improper installation can cause a significant safety hazard. Reverse polarity causes the buzzing to become louder when devices are plugged in.
