About 4/0 AWG THHN THWN-2 Aluminum Cable:

This 4/0 AWG THHN/THWN-2 aluminum wire is designed for reliable power distribution in both dry and wet locations, with ambient temperatures up to 90°C. Rated for 600 volts, it features durable PVC insulation and a tough nylon jacket for added protection and reduced friction during installation. It is installed in conduit and raceway. It is a cost-effective solution for feeder runs, service entrance wiring, and high-demand branch circuits in commercial, residential, and light industrial systems.

Applications:

• Service entrances for large homes, commercial, or light industrial buildings (205 amps)

• Feeders to subpanels in apartments, workshops, or offices

• Branch circuits for large HVAC units or industrial motors

• Secondary distribution to main panels in multi-unit buildings

• Long-distance building wiring where copper is too costly

• Control circuits requiring high ampacity

Why Choose 4/0 AWG Aluminum THHN/THWN-2 Wire?

With an ampacity of 205 amps at 90°C, 4/0 AWG aluminum THHN/THWN-2 wire provides a cost-effective alternative to copper for heavy-duty applications. It’s ideal for long feeder runs, service entrances, and high-load branch circuits where weight, budget, and code compliance are critical factors.

Construction:

Conductors:

THHN / THWN-2 / T90 conductor is a 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.
