Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit and verify absence of voltage with a meter before making any connections. Strip conductors to the appropriate length, hold parallel, and twist the connector clockwise until firmly seated with no bare copper exposed. Do not overtighten to the point of damaging conductor strands or cracking the shell.
