Circuit breaker rating refers to the maximum current that the breaker can safely interrupt without causing damage.

• Circuit breaker rating is typically expressed in amps (e.g. 15A, 20A, 30A).

• The rating should be chosen based on the maximum current that will flow through the circuit.

• It is important to select a circuit breaker with a rating higher than the maximum current to prevent tripping.

• Using a circuit breaker with a ...read more
