Circuit Breaker Resistance Test. A very low resistance value (close to zero ohms) indicates good condition, whereas high resistance suggests a problem. With the breaker still in the “on” position, check the resistance. Contact resistance test to measure the. Locate the main or general switch to your electrical panel box and flip it to the off position. With the circuit powered on, measure the voltage across the breaker. For circuit breakers, switches, and similar equipment with moving contacts, neta electrical testing standards define a minimum deviation of 50% between phases. Insulation resistance testing of the circuit breaker’s control wiring. Dc overpotential test of the circuit breaker’s insulation systems. The resistance test on circuit breakers is the safest method of testing them for faults, as you don’t need power running through them to make a proper diagnosis.
