Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before making or inspecting any wire connections. Strip conductors to the appropriate length, insert into the connector, and twist clockwise until the connector is snug and no bare wire is exposed at the base. Do not over-torque or force mismatched wire sizes into the connector.
