Circuit breakers play a crucial role in your home’s functionality, safety, and comfort. These protective devices keep your electrical system protected by shutting off power to your lights and outlets when they detect a fault. This automatic response happens instantly, reducing the risk of electrical hazards and property damage for enhanced safety. If your circuit breakers become damaged, malfunction, or wear out, Mr. Electric is your trusted partner for exceptional repair and replacement services. Here’s what to expect when you hire licensed electricians in Boulder, CO to upgrade your breakers.

Inspection and Diagnosis

A frequently tripping circuit breaker is a red flag that you shouldn’t ignore. The technician will thoroughly inspect your electrical system, from the wiring to switches and other equipment, ensuring an accurate diagnosis. If turning on the flipped breaker and resetting the switch doesn’t fix the problem, a full upgrade is needed to restore functionality. Additionally, hot plugs, discolored outlets, and fraying appliance cords suggest underlying breaker issues. Whether it is overloading or other issues, the electrical service team can assess the situation, pinpoint the root cause, and recommend the best course of action.

Shut-Off Power

Safety is a top priority when it comes to electrical work, and a circuit breaker replacement is no exception. Before any work can begin, the technician will shut off the power to create a safe working environment. When working with circuits or circuit breakers, professionals first locate the main panel and turn off each switch to cut off the power in your home. After successfully disabling the breaker, a voltage tester or multimeter is used to ensure no current is flowing beyond the service panel. This is a crucial step in preventing shocks and other safety hazards.

Removing the Faulty Breaker

Once the electrician disables the existing circuit breaker, they will unscrew the faceplate and remove it to access the wires and other internal components. A flathead screwdriver helps loosen the wires that connect the circuit wires to the breaker and tuck away any exposed wires to prevent safety hazards. Additionally, removing the old panel helps check for other signs of deterioration, such as moisture, rust, melting, pests, and burn marks. While these irregularities may not raise concerns initially, they can cause devastating damage if left unchecked.

Installing the New Breaker

Circuit breakers come in different sizes and types, and ensuring you choose the right one for your home can make a big difference. The electrical service provider will ensure that the new circuit breaker is securely pushed into position and aligns perfectly with the bus bar. Proper alignment is important when screwing on the old breaker wire and tightening any loose terminal screws. Finally, the panel cover is secured, and the power is restored at the panel.

Testing

After restoring the power to your circuit breaker, the technician will ensure it is installed correctly. A final inspection is done to detect hidden issues and fix them quickly before they escalate. If the system is running as expected, expect a scheduled follow-up maintenance check to ensure everything remains in top condition. Additionally, regular inspections after installation help comply with local electrical codes and regulations.

When you hire a licensed and insured electrical service provider for circuit breaker upgrades, expect them to confirm your appointment, communicate clearly, and go over the work order. A professional prioritizes safety throughout the process and respects your home until completion. You can expect optimal functionality, a clean work area, and a detailed report for peace of mind.
