The THHNCU-GENERIC thhn3/0strblumr is a 3/0 AWG stranded copper THHN building wire with blue PVC insulation and a nylon jacket, rated for 600 volts. It is designed for use in conduit in commercial and residential electrical installations where a durable, heat-resistant conductor is required. The 19-strand construction provides flexibility during pull-in. Current capacity is 165 amps at 60 degrees C, 200 amps at 75 degrees C, and 225 amps at 90 degrees C, with a dry-location temperature rating of 90 degrees C. This wire is sold cut to length, making it well suited for panel feeds, feeder runs, and branch circuit work handled by licensed electricians.
This wire is commonly used in conduit runs for service entrance feeders, subpanel feeds, motor branch circuits, and large commercial branch circuits where 3/0 AWG ampacity is required. The blue insulation aids in phase identification and color-coding of multi-conductor conduit runs. Typical installation scenarios include switchgear rooms, commercial tenant buildouts, industrial equipment connections, and residential service upgrades. Cut-to-length purchasing reduces on-site waste when the required run length is known in advance.
Designed for use in conduit as an OEM-style THHN building wire suitable for 600-volt electrical distribution systems in dry locations where 3/0 AWG copper conductors are specified.
Installation must 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 and panel before terminating conductors. Use appropriate pulling lubricant and conduit fill calculations per NEC Chapter 9 to avoid exceeding conduit capacity. Do not use this wire in wet locations unless the installation also meets wet-location rating requirements.
