Detecting circuit breaker leak check

Step 1. Turn off the main breaker at your home's service panel (breaker box) and look at the electric meter. The meter should not be running -- if it is, you have discovered the leak. It is somewhere between the power leads and the panel, and you need to have it fixed immediately. Call an electrician.

    2020-6-16If the breaker reads 0, it needs to be replaced. If you have a double pole breaker, make sure the reading is between 220-250 V. A faulty double pole breaker will read at 120 V, meaning its only operating at half power. The voltage of your circuit breaker depends on the size of the wire that comes into the circuit.349,001 views
