2 AWG Aluminum XLP USE-2 RHH/RHW-2 Direct Burial Building Wire

Allowable Ampacity for 2 AWG Aluminum XLP USE-2 RHH/RHW-2 Direct Burial Building Wire: 95 Amps

Description

This cable is a high-capacity power distribution cable with multiple ratings—RHH, RHW-2, XLP, and USE-2—designed for underground and raceway installations. The RHH rating indicates heat resistance for dry locations, while RHW-2 ensures water resistance and a 90°C maximum operating temperature in both wet and dry conditions. The XLP (cross-linked polyethylene) insulation enhances durability, abrasion resistance, and electrical performance. The USE-2 rating makes it suitable for service entrance installations below ground and direct burial.

USE-2 cables are commonly used for power distribution, service entrance below ground, and direct burial, as well as in raceways. This electrical cable is approved under the National Electrical Code (NEC), except for use in cable trays. It supports a voltage rating of 600V and operates at a maximum temperature of 90°C in wet and dry environments.

Ampacity Ratings (Per NEC 310.16):

In Free Air (90°C) → 115 Amps

In Direct Burial or Raceway (90°C) → 95 Amps

Common Applications for 2 AWG Cable:

Primary and secondary underground power distribution for large residential and commercial buildings.

Service entrance wiring for higher-capacity single-phase and three-phase systems.

Feeder circuits supplying power to large electrical panels, subpanels, and industrial loads.
