350 MCM XHHW-2 Stranded Copper Building Wire

350 MCM XHHW-2 Stranded Copper Building Wire

Applications:

350 MCM copper XHHW-2 is installed in conduit and other NEC-recognized raceways for services, feeders, and branch circuits, in wet or dry locations at up to 600V. It's rated 310A at 75°C and 350A at 90°C. Typical uses:

• 300A feeders at full rating

• 350A home services under NEC 310.12

• 600A services run as two parallel sets

• 1200A services run as four parallel sets

350 MCM XHHW-2 Copper Data Center Applications

In data centers, 350 MCM copper XHHW-2 is used for feeders between switchgear, UPS systems, PDUs, and panels. Data center loads run continuously, so NEC 215.2 sizes feeders at 125% of the load unless the breaker is 100% rated.

• Two parallel sets for 400 kVA UPS input and output (481A full load, 601A at 125%)

• Four parallel sets for 1200A switchboards

• Generator feeders to automatic transfer switches
