Also Known As:

250 thhn cable, 250 thwn cable, 250 mcm thhn cable, 250 mcm thwn cable, 250 thhn aluminum, 250 pvc insulated, 250 pvc insulated wire, 250 pvc insulated aluminium wire, 250 pvc sheathed cable, 250 pvc flexible cable.

Conductors:

THHN / THWN-2 / T90 conductor is a compact soft drawn bare 8000 series aluminum, with Class B stranding per ASTM. Stranded conductors reduce power loss and are also easier to use in applications where flexibility is vital. 

Insulation:

THHN / THWN-2 / T90 has abrasion, heat, moisture, oil, and acid alkaline resistant polyvinyl chloride (PVC) insulation.

Jacket:

THHN / THWN-2 / T90 cables have a clear abrasion, heat, sunlight, moisture resistant, and low coefficient of friction nylon jacket. Standard stock colors include: black, red, blue, white, brown, orange, yellow, gray, purple, and green.
