4 ALUMINUM RHH/RHW-2 XLP USE-2 DIRECT BURIAL

Allowable Ampacity for 4 AWG ALUMINUM RHH/RHW-2 XLP USE-2 DIRECT BURIAL: 65 Amps

Description

This cable is a versatile 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) → 85 Amps
• In Direct Burial or Raceway (90°C) → 65 Amps

Common Applications for 4 AWG Cable:

• Primary and secondary underground power distribution for larger residential and light commercial buildings.
• Service entrance wiring for single-phase and three-phase power systems.
• Feeder circuits for panelboards and distribution equipment.
• Direct burial installations for medium-duty electrical loads.
• Industrial and agricultural installations requiring cost-effective underground wiring.
