The THHN-GENERIC thhn12strgrn500r is a 12 AWG stranded copper THHN building wire supplied on a 500-foot spool. The conductor is made from copper with a 19-strand configuration, covered in PVC insulation rated for 600 volts and 90 degrees C in dry environments. This wire is used in branch-circuit and feeder wiring inside conduit in residential, commercial, and light industrial electrical systems. Licensed electricians install this wire during rough-in and finish electrical work where NEC-compliant conductors are required.
Green-jacketed THHN wire is the standard color designation for equipment grounding conductors in most electrical installations. This 500-foot spool is suited for larger jobs where running a continuous ground through conduit is required. It fits common applications including panel feeders, subpanel grounding, motor circuit grounding, and general branch-circuit equipment grounding runs in EMT, rigid metal conduit, or ENT.
Designed as a standard THHN-rated building wire suitable for use in conduit-wired electrical systems where a 12 AWG stranded equipment grounding conductor is required.
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 zero voltage with a meter before making any terminations. This wire is rated for use inside conduit only and is not approved for direct burial or exposed outdoor use without additional protection. Pull slack into the conduit run before cutting from the spool to avoid short lengths at termination points.
