Each year, electricians sustain injuries while attempting to change ballasts without tripping the breaker because they're trying to avoid disconnecting other lighting and equipment from power. That's why changes to NEC and UL standards require a means of disconnecting power to non-residential fluorescent lighting ballasts. ABB developed the first UL listed product to meet this need. In response to customer demand, the Sta-Kon push-in luminaire disconnect provides all the same safety benefits as the original, but installs even faster and easier. Installs easily just strip de-energized wires and insert Enables electricians changing ballasts to easily disconnect incoming power for safer servicing without having to trip the main power breaker Disconnect halves snap together and separate easily but won't accidentally disconnect Fool-proof design eliminates the potential for incorrect installation and reverse polarity Fits through 1/2 in knockouts for easy retrofit
