Disco Madness: The Whys and Wheres of Disconnects

In the event of an emergency, disconnect switches are used to rapidly disconnect the external power source conductors from the circuits in a building or structure (National Electrical Code Sections 690.13; 230.70). A common disconnect of this type is the AC service entrance disconnect for a house. Utilities require disconnects on grid-tied PV systems to protect their workers from possible electrocution.
