Step-by-Step Circuit Breaker Repair Guide:

Note: Safety is paramount when working with electricity. Always shut off the power supply to the affected circuit and use personal protective equipment, such as safety glasses and gloves.

Step 1: Safety First

Begin by turning off the power to the circuit you are working on. This step is crucial to avoid electrical shocks or accidents. Always use a voltage tester to double-check that there is no electricity running through the circuit.

Step 2: Remove the Circuit Breaker Panel Cover

Unscrew and remove the panel cover to access the circuit breaker. Use a screwdriver for this step.

Step 3: Identify the Problem

Examine the circuit breaker and identify the issue. Common problems include tripped breakers, loose connections, or a malfunctioning breaker.
