What is the function of a lick-breaker?

A lick-breaker is a important safety device in electrical systems, particularly for maintenance and troubleshooting purposes. Its primary function is to disconnect or isolate a circuit, allowing linemen or technicians to safely perform maintenance or repairs on electrical equipment or distribution lines. By isolating a section of the circuit, it ensures that the area is de-energized, reducing the risk of electrical shock or accidents during work.

This functionality is crucial, as it provides a necessary safety measure for personnel working on or near live wires. Maintenance, repairs, and inspections can only be safely carried out when it's clear that power is not flowing to the area being worked on, which is precisely what a lick-breaker enables.
