3 XLP USE-2 RHH RHW-2 Copper Building Wire
Ampacity Rating:
- In Free Air (90°C): 130 Amps
- In Raceway or Direct Burial (90°C): 110 Amps
Also Known As:
3 XLP USE-2 RHH RHW-2 Copper Building Wire, 3 Copper RHH Wire, 3 Copper RHH Cable, 3 Direct Burial Electrical Cable, 3 Direct Burial Power Cable, 3 Direct Burial Service Entrance Cable, 3 Underground Service Entrance Cable.
Description
This 3 AWG copper building wire is a high-capacity electrical conductor with multiple ratings—RHH, RHW-2, and USE-2—designed for residential, commercial, and industrial applications. It is suitable for both wet and dry locations, with a 90°C maximum operating temperature in either environment. The USE-2 rating makes it ideal for direct burial and underground service entrance applications.
With a 600V rating, this wire is commonly used in lighting, power distribution, photovoltaic connections, raceways, and aerial installations. It is also suitable for conduit installations per NEC specifications. The annealed soft copper conductor provides excellent conductivity and flexibility, making it a superior alternative to aluminum conductors in compact conduit installations.
Applications:
- Underground service entrance cable for direct burial in residential and commercial installations.
- Feeder and branch circuits for higher-load electrical systems in homes, businesses, and industrial settings.
- Raceway and conduit installations where increased ampacity is required.
- Aerial applications for outdoor power distribution with UV and weather resistance.
- Photovoltaic (solar panel) systems requiring moderate to high power capacity.
Construction:
Conductor:
RHH/RHW-2/USE-2 conductors are made of annealed soft copper. Compared to aluminum, this conductor performs better in smaller conduits.
Insulation:
The cable has an abrasion, heat, and moisture resistant cross-linked polyethylene insulation (XLPE). The insulation is durable in harsh conditions.
