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

If a circuit breaker sparks when you turn it on, stop and treat it as an electrical hazard—leave it off and do not try again. The most common causes are a loose wire, a short circuit, or moisture at the breaker, all of which can arc and damage the contacts. A quick re-try can make arcing worse; I’ve seen contacts weld together from repeated flips. Our team handles urgent electrical calls in the Holiday area, and 24/7 emergency service is available with upfront, by‑the‑job pricing and a worry‑free guarantee.

Do this next, in order:

• Stand clear; if it’s safe to reach, switch the main power off.
• Unplug or switch off any device on that circuit.
• Do not reset a hot, buzzing, or scorched breaker, and never use water near the panel.
• Call a licensed electrician for emergency service and note the breaker brand and size.

If you see flames, smoke, or melting plastic, evacuate and call 911 before contacting an electrician. <br/> Updated: 2026-03-12 <br/> Need help in Holiday, FL?
