Common Circuit Breaker Service Questions

You can identify Federal Pacific Stab-Lok® breakers by the label on the front of the panel that says “Federal Pacific” or “FPE” and the breaker itself should say “Stab-Lok®” either on the face of the panel or a label inside the panel door. The Stab-Lok® breakers are also usually red on the breaker switch.

A full home inspection can cost nearly $350 on average, but inspecting the breaker box specifically is likely to be lower, between $100 and $200. Don’t confuse this service with a basic breaker trip check, which doesn’t take long and is usually billed at $40 to $50 per hour.

If the electrician discovers a serious problem and needs to replace a breaker, it can cost between $100 and $200 in additional expenses. Although rare, replacing the electrical panel typically costs between $500 and $2,000.

Knowing if and when your circuit breaker is failing or faulty can prevent costly damage. If you notice any of the following signs, call a local electrician to help. 

  • The breaker frequently trips

  • The breaker doesn't stay in the 'on' position or reset properly

  • You hear buzzing or humming noises coming from the breaker

  • There's discoloration around the breaker switch

  • There's a burning smell or visible signs of damage on the breaker

The major difference between a GFCI breaker and an AFCI breaker is that a GFCI breaker protects against fatal shocks while an AFCI breaker prevent electrical fires. A GFCI breaker senses when the electrical current to ground is overloaded and trips to prevent major accidents or injuries. AFCI breakers trip when it detects dangerous electrical arcing.

A bigger breaker alone probably won’t fix your problem of frequent tripping. But if you upgrade an electrical circuit to a higher amp rating, or upgrade your breaker box to handle more amps, it could solve your tripping problems. Consult a qualified electrician about the best course of action.
