Feeder tap conductors are intended to be protected from what by the feeder OCPD?

Feeder tap conductors are primarily designed to be protected from short-circuit and ground fault conditions by the feeder Overcurrent Protective Device (OCPD). This protection is crucial because short-circuits and ground faults can lead to excessive current flow that poses a risk of overheating, equipment damage, and potentially fire hazards.

The feeder OCPD ensures that when a fault occurs, it will trip and disconnect the affected circuit before the damage can escalate, thus safeguarding the feeder tap conductors. This targeted protection is vital in maintaining the integrity of the electrical system and ensuring the safety of both the installation and the personnel interacting with it.

While overload conditions are a concern, the more acute threats of short-circuits and ground faults are the primary focus for OCPD protection in this scenario. Similarly, "all overcurrents" is overly broad, as it includes both overloads and other conditions that may not be directly managed through the feeder OCPD in the same way as short-circuits and ground faults. Therefore, the correct answer is that feeder tap conductors are specifically intended to be protected from short-circuit and ground fault conditions by the feeder OCPD.
