400 MCM ALUMINUM RHH/RHW-2 XLP USE-2 DIRECT BURIAL
Allowable Ampacity for 400 MCM ALUMINUM RHH/RHW-2 XLP USE-2 DIRECT BURIAL: 290 Amps
USE-2 cables are power distribution cables for service entrance below ground and direct burial, as well as raceways. The electrical cable is approved according to the National Electric Code, except for the use in cable trays. The maximum operating temperature for this electrical cable is 90°C in wet and dry locations. The voltage rating is 600 volts.
Also Known As:
400 mcm wire, 400 mcm aluminum wire, 400 mcm wire size, rhh wire, rhh cable, bury cable, direct burial electrical cable, direct burial mc cable.
USE-2 meets or exceeds the following standards
Requirements of the National Electrical Code
ASTM standards B 800, B 801
400 MCM Aluminum RHH wire has USE-2 conductor that is compact soft drawn bare made of 8000 series aluminum, with Class B stranding per ASTM. The conductor is the electrode in the cable and is responsible for transmitting electric current.
USE-2 has abrasion, heat, and moisture resistant cross-linked polyethylene (XLP) insulation. The conductors are normally cabled together with XLP insulated aluminum ground or bare copper ground and covered with reinforced binder tape. XLP insulation is tough and resistant to impact, abrasion, chemicals, acids, oils, industrial solvents, and changes in weather.
The cable jacket used in its design is Polyvinyl Chloride (PVC). The jacket protects the inner components of the cable from potentially damaging external forces. PVC is robust and resistant to oil, sunlight, water, flames, acids, chemicals, radiation, impact, abrasion, and weather changes. Sequential footage markings that help the user identify the appropriate length during installation are noted on the cable jacket.
