"This was by far the best contractor experience I’ve had in many years. Rob is friendly, knowledgeable and professional. He was able to work within my budget and kept me informed during every stage of the process. My generator was ordered and installed in only one week, which was also very impressive. I would highly recommend Buckley & Son Electrical Contractors."

Electrical questions, answered by experts

The cost to install or replace a circuit breaker depends on the price of the unit itself and the complexity of the installation. A new circuit breaker typically costs between $10 and $100, with standard breakers being the most affordable and GFCI or AFCI types costing more. If you are upgrading to a higher amperage, a 200-amp circuit breaker can cost between $250 and $350. The average total cost for professional installation is around $700, but this price varies. A simple replacement into existing wiring will cost less than a more complex project that requires opening walls, running new wires, and securing permits.

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

The number of outdoor outlets that can be on one circuit depends on the circuit's capacity and the electrical load of each outlet. Outdoor outlets should ideally be on a dedicated circuit that is not shared with other outlets, and each outlet should be rated for at least 15 amps. A circuit rated for at least 20 amps is recommended. It’s important to use GFCI protection for all outdoor outlets to prevent electrical shocks. Overall, it's crucial to avoid overloading the circuit and take necessary safety precautions.

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

Smart meters send the readings over a wireless wide area network (WAN) to the power company. This network allows sending small amounts of data slowly over long distances, which is perfect for smart meter readings that occur monthly. If you would prefer a smart meter, contact your power company and consider springing for the cost of replacing your electric meter.
