Which of the following is a method to prevent nuisance tripping of a circuit breaker?

Correctly sizing the circuit breaker is fundamental to preventing nuisance tripping. Circuit breakers are designed to trip when current exceeds a certain threshold to protect the circuit and prevent overheating or electrical fires. If a breaker is undersized for its application, it may trip unnecessarily under normal operating conditions, leading to frequent interruptions in service.

By selecting a circuit breaker with an appropriate rating for the specific load it will be protecting, it ensures that the breaker can handle the current without tripping during normal operation. This correct sizing will take into account factors such as the calculated load, potential inrush currents, ambient conditions, and any other relevant parameters to achieve optimal performance.

Other options, while they may seem related, do not effectively address the issue of nuisance tripping in the same way. Increasing the voltage can create additional risks without resolving the underlying problem of the breaker sizing. Using a higher amperage rate can compromise safety by potentially allowing excessive current to flow, increasing the risk of damage or fire. Reducing the load on the panel might provide a temporary solution, but it does not directly address the issue of the breaker being improperly sized for its designated load.
