Where 32 amps is flowing in circuit conductors protected by a 30-amp breaker, this is an example of which condition?

• A. Short circuit
• B. Ground fault
• C. Overload
• D. Any of these

Answer: (C)

The situation shows an overload. An overcurrent occurs when current exceeds what the circuit’s protection and conductors are designed to carry. A 30-amp breaker is meant to trip when the current goes above its rating to protect the wiring from overheating. Here, 32 amps are flowing, which is higher than the breaker’s rating, so it’s an overload condition. It isn’t a short circuit (which would be a fault path causing a very large surge) and it isn’t a ground fault (which involves current leaking to ground). So the best explanation is overload.
