Designed as an OEM-style replacement and general-use connector suitable for commercial, industrial, and residential electrical wiring systems requiring 22 to 16 AWG twist-on terminations.
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify absence of voltage with a meter before making or disturbing any connections. Strip conductors to the appropriate length per connector instructions and twist the connector clockwise until firm resistance is felt. Do not overtighten or use with conductors outside the rated AWG range.
