How to Test Circuit Breakers

Finding out if you need to replace a breaker is easy if you follow these tips.

You will need

  • Multimeter
  • Circuit breaker

Step 1 Open the electrical box Open the circuit breaker box and locate the switch that corresponds to the area you want to test.

Step 2 Test the switch Determine whether the breaker is in the On or Off position. If it’s off, flip to the On position.

Step 3 Connect the prongs Touch one of the multimeter’s prongs to the terminal screw, and touch the other prong to the ground screw.

Step 4 Check the readout Check the readout on the multimeter or look for an indicator light. If no voltage is indicated, then no power is reaching the breaker and it will need to be replaced.
