2/0 Aluminum RHH/RHW-2 XLP USE-2 Direct Burial
Allowable Ampacity for 2/0 AWG ALUMINUM RHH/RHW-2 XLP USE-2 DIRECT BURIAL: 145 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 ensures heat resistance in dry locations, while RHW-2 makes it water-resistant and suitable for 90°C operation in both wet and dry conditions. The XLP (cross-linked polyethylene) insulation enhances durability, abrasion resistance, and electrical performance. The USE-2 rating allows for direct burial and underground service entrance installations.
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) → 175 Amps
- In Direct Burial or Raceway (90°C) → 145 Amps
Common Applications for 2/0 AWG Cable:
- Primary and secondary underground power distribution for commercial, industrial, and large residential buildings.
- Service entrance wiring for high-capacity single-phase and three-phase electrical systems.
- Feeder circuits for high-power panels, subpanels, and heavy industrial loads.
- Direct burial installations for long-distance power transmission with minimal voltage drop.
- Utility, infrastructure, and agricultural applications where high ampacity and moisture resistance are essential.
This 2/0 AWG aluminum cable is ideal for large service entrances, feeder circuits, and underground power distribution requiring up to 145 amps.
