Thhn 500 Kcmil Stranded Copper Wire Black thhn500mcmstrblkmr

Product Description

The thhn500mcmstrblkmr is a 500 kcmil stranded copper conductor THHN wire with black PVC insulation and a nylon jacket. Rated for 600 volts and 90 degrees F in both dry and wet environments, this wire handles up to 380 amps at 75 degrees C, making it well suited for high-ampacity branch circuit and feeder runs. The 37-strand configuration provides flexibility during pulls through conduit. This product is sold as a cut-to-length spool and is installed by licensed electricians in commercial and industrial applications where large-gauge conductors are required.

This wire is appropriate for use in conduit systems serving high-load equipment, service entrance feeders, large motor circuits, and similar applications requiring 500 kcmil conductors. The black insulation color aids in phase identification during installation. At 1661 pounds per thousand feet and an outer diameter of 0.938 inches, conduit fill calculations and pulling equipment selection should be completed before beginning the run. This conductor is suited for both residential service upgrades and commercial power distribution installations.

Compatibility

Designed for use in conduit-based wiring systems requiring 500 kcmil THHN conductors rated at 600 volts, suitable for feeders, branch circuits, and service entrance applications per NEC guidelines.

Installation Notes

Installation of 500 kcmil THHN wire must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before terminating conductors. Use appropriately rated conduit, connectors, and lugs for 500 kcmil copper conductor. Calculate conduit fill per NEC Article 310 and use mechanical pulling equipment rated for the weight and friction load of this large-gauge wire.
