- Product Details
38mm² THHN Wire is a high performance American Standard wire. The cable is constructed with high quality conductors encased in a heat-resistant nylon jacket that provides superior electrical performance and mechanical strength. The conductors are suitable for use in dry locations where temperatures do not exceed 90°C. Type THHN building wire is suitable for use in power transmission and control circuits in commercial buildings and industrial facilities. Also 38mm² THHN copper wire cable can be used in bridge installations, open wires, conduits, service entrances, feeders and permanently installed branch circuits.

FAQ
What is the AWG equivalent of 38mm² THHN wire?
38mm² falls between 2 AWG (33.6mm²) and 1 AWG (42.4mm²). In metric markets (like the Philippines), it is the standard upgrade from 30mm² and is typically used where 2 AWG would be specified in NEC standards, offering slightly higher current capacity than standard #2 AWG.
What is the ampacity rating of 38mm² THHN?
In a raceway (conduit) at 75°C (standard termination rating), 38mm² THHN is generally rated for 115 to 130 Amps (depending on the specific code, e.g., PEC). It is most commonly protected by a 125 Amp or 150 Amp circuit breaker, depending on installation conditions.
Can I use 38mm² THHN for a residential Service Entrance?
Yes. It is the standard service entrance wire for large residential homes or small commercial buildings requiring a 100A to 125A service.
