Ballast-to-luminaire disconnects are insulated plug-and-socket connectors that allow quick connection and disconnection of ballasts and luminaires without turning off the incoming power to perform rework and installations. The connectors plug in and create tight holds to transfer and ground power from the ballast to the lighting fixture. Each disconnect has ports where wires push into and catch on an internal tab that bites into the conductor to hold, splice the connection, and prevent it from pulling out. Typical uses include installing or retrofitting fluorescent or HID lighting.
