What is the Price of 4/0 Aluminum Wire? (200-Amp Service Guide)

What is the Price of 4/0 Aluminum Wire? 

If you are upgrading a home to 200-amp service or installing a large sub-panel for a fast-charging EV station, 4/0 Aluminum wire is the industry standard choice. While it offers massive cost savings over copper, the "real cost" depends on whether you are burying it, pulling it through a pipe, or running it through a basement.

Here is the breakdown of the most common 4/0 Aluminum options to help you choose the right one for your 200-amp project.

4/0 XHHW-2 Aluminum (Single Conductor)

Estimated Price: $ (Lowest) Best For: Pulling through conduit for 200-amp main service feeders. This is a single, thick strand of high-performance insulated wire. For a standard 200-amp main service, you will typically need three of these (two hots and a neutral) or four if a dedicated ground is required.

Installer’s Insight: Pulling 4/0 through conduit can be a workout. We recommend XHHW-2 because its cross-linked insulation is much slicker than standard THHN, which significantly reduces friction when you're pulling through long conduit runs or multiple 90-degree bends.

4/0-4/0-4/0-2/0 SER Aluminum (The 200-Amp Sub-Panel King)

Estimated Price: $$$ (Higher) Best For: Large 200-amp sub-panels in mansions, estates, or commercial buildings. SER cable bundles three 4/0 conductors and a 2/0 ground wire into one heavy-duty, gray jacket. This "all-in-one" construction is designed for interior use without the need for conduit.

Installer’s Insight: When running a 200-amp feed through a finished interior, SER is a lifesaver. It allows you to skip the labor-intensive process of bending 2-inch or 2.5-inch conduit, saving you days of work on a large residential project.

4/0 Aluminum URD (The Direct Burial Specialist)

Estimated Price: $$ (Moderate) Best For: Running 200-amp power underground to a house or large detached building. Often called "Sweetwater" or "Vassar" in the industry, 4/0 URD is typically "triplexed" (three wires) or "quadruplexed" (four wires). It is built with a rugged jacket designed to be buried directly in a trench without a pipe.

Installer’s Insight: 4/0 URD is strictly an outdoor cable. Because it doesn't have a fire-rated jacket, it cannot be run more than 5 feet inside a building. If your panel is deep inside the house, you’ll need to transition to XHHW-2 or SER at the entrance point.

4/0 XLP/USE-2 RHH/RHW-2 (The Triple Rated Solution)

Estimated Price: $$ (Moderate) Best For: Heavy-duty solar arrays and seamless underground-to-indoor runs. This is the "Triple Rated" workhorse. Unlike standard URD, this wire is cross-linked (XLP) and carries the RHW-2 rating, meaning it is fire-retardant and legal to run inside your building. It is also highly resistant to sunlight, moisture, and extreme temperatures.

Installer’s Insight: This is the ultimate choice for large-scale solar projects. Because it is rated for both direct burial and indoor use, you can run it from a ground-mounted solar rack directly into the building's electrical room without needing an external junction box to switch wire types.

4/0-3C Aluminum MC Cable (Metal Clad)

Estimated Price: $$$ (Higher) Best For: Commercial 200-amp feeders and multi-family housing. MC cable features three 4/0 conductors and a bare ground wrapped in a flexible aluminum armor. It provides the protection of conduit with the flexibility of a cable.

Installer’s Insight: For commercial builds where conduit is usually required, using 4/0 MC cable can cut your labor costs by half. You can fish it through metal studs and open ceilings in a fraction of the time it takes to run rigid pipe.
