What is the function of a disconnect switch?

The function of a disconnect switch is primarily to interrupt the flow of electricity and isolate equipment for maintenance. This is a critical safety feature in electrical systems. By using a disconnect switch, workers can ensure that certain sections of a circuit are de-energized, preventing accidental electric shocks or injuries while maintenance or repairs are performed. Disconnect switches are essential for ensuring that workers can safely access and service electrical equipment without the risk of electrical hazards.

In addition, these switches serve as a means to segregate portions of the electrical system for troubleshooting or upgrades, making them vital for operational safety and efficiency. Knowing how to utilize disconnect switches is crucial for linemen as it significantly contributes to maintaining safe working conditions in various scenarios.
