Overcurrent protective device(s) should not be provided in a service entrance main panel. True or false?

Overcurrent protective devices (OCPDs) play a critical role in ensuring the safety and integrity of electrical systems by preventing excessive current that could lead to overheating or fires. In a service entrance main panel, it is essential to have OCPDs to protect the service conductors and the entire system from overcurrent situations.

The service entrance main panel is the point where power from the utility enters a building, and it typically requires overcurrent protection to shield against potential faults. This protection can take the form of circuit breakers or fuses, which disconnect the electrical supply in the event of an overload or short circuit. By doing so, OCPDs help maintain system stability and enhance safety for both the electrical infrastructure and the occupants of the building.

While there are cases where additional protective measures might be specified based on the design or particular requirements of a system, the general rule is that overcurrent protective devices are essential in a service entrance main panel. Thus, stating that OCPDs should not be provided in such a panel is incorrect.
