Common Signs of a Faulty Commercial Electrical Panel
As electrical panels age, they may begin to malfunction. That can cause circuit breakers to trip when they shouldn’t or fail to trip when they should. It can also cause problems as subtle as flickering lights. Some of the signs that an electrical panel needs to be upgraded are easier to identify than others. Sometimes you can tell just by the age of your panel alone. Professionals recommend that property owners get electrical panel upgrades every 25 years. If your panel is more than 25 years old, you should have it inspected regularly, and you should seriously consider upgrading it. Some of the other signs that it is time to upgrade or replace your electrical panel include:
- Crackling noises coming from the electrical panel
- Corrosion or rust is present on the circuit breakers
- Your electrical panel is warm to the touch
- Appliances and electronics that are sluggish or run at less than full power
- You need to use extension cords regularly
- Your building only has 60-amp service
- Your building has 100-amp service, but the breakers still trip when you operate specific appliances
- Your property has a fuse-block panel or a split-bus panel, which lacks a main breaker
