Is it an accepted practice to open the normal circuit load with a sectionalizer?

Using a sectionalizer to open the normal circuit load is considered an accepted practice in various scenarios within the electrical distribution system. Sectionalizers are designed to automatically isolate faults on overhead and underground distribution systems, allowing for the maintenance of service to other parts of the network.

When a fault occurs, sectionalizers can detect the faulted section and open the circuit, assisting in maintaining reliability and minimizing outages for unaffected customers. This capability is key in ensuring the system operates efficiently and safely. Thus, opening a normal circuit load with a sectionalizer is part of well-established operational protocols that help maintain reliability in distribution systems.

The other options reflect scenarios that do not align with the standard operating procedures established in the field. Proper training and understanding of sectionalizers are crucial for linemen to utilize these devices effectively and judiciously.
