What should I do if my circuit breaker sparks when turned on?

If a circuit breaker sparks when turned on, stop using it and treat it as a potential electrical fault. The most common cause is a worn breaker or a loose connection that creates an electrical arc. This can be serious because arcing can overheat wiring and damage the panel. A breaker that sparks even with nothing plugged in often points to failing internal contacts, not a bad appliance. Our licensed electricians handle urgent breaker issues across the Framingham area with 24/7 response.

Take these steps right away:

• If you see a big flash, hear buzzing, smell burning, or the panel feels hot, switch the main power off and call an emergency electrician.
• Do not keep resetting the breaker; leave it off.
• Unplug devices on that circuit and keep people away from the panel.
• Arrange a professional inspection to check for loose terminations, damaged wiring, or an improperly sized breaker.

If fire, smoke, or melting is present, exit and call 911 before calling an electrician.
