What is the Price of #6 Aluminum Wire? (50-Amp Guide)

What is the Price of #6 Aluminum Wire?

If you are installing a 50-amp RV hookup, a hot tub, or a Level 2 EV Charger, #6 Aluminum wire is the most cost-effective way to get the job done. While many people automatically reach for expensive #6 copper, modern high-quality aluminum cable can handle 50-amp loads safely for roughly one-third of the cost.

Here is the breakdown of the most common #6 Aluminum options and how to choose the right one for your 50-amp project.

#6 XHHW-2 Aluminum Wire (Single Conductor)

Estimated Price: $ (Lowest) Best For: Pulling through conduit for EV chargers or small sub-panels. This is a single strand of high-performance insulated wire. For a standard 50-amp EV circuit, you typically need three or four strands (two hots, one neutral, and one ground).

Installer’s Insight: EV charging is considered a continuous load, meaning the wire carries its maximum current for hours at a time. We use XHHW-2 because its cross-linked insulation handles heat better than standard PVC-jacketed wires, which is critical for long charging sessions.

#6-6-6-6 SER Aluminum Wire (The EV Specialist)

Estimated Price: $$$ (Higher) Best For: Residential EV charger installs and 50-amp sub-panels. SER cable bundles three #6 conductors and a #6 ground wire into one flexible, gray jacket. It is designed for indoor use and can be run through walls or across ceilings without the need for conduit.

Installer’s Insight: Many EV chargers only accept copper wire at their terminals. An easy "pro move" is to run #6 Aluminum SER from your main panel to a small disconnect box near the charger, then switch to a short run of copper for the final connection. This gives you the savings of aluminum with the compatibility of copper.

#6 Aluminum URD (The Underground Workhorse)

Estimated Price: $$ (Moderate) Best For: Running 50-amp power underground to a shed, hot tub, or RV post. #6 URD is typically "triplexed" (three wires) and is rated for direct burial. This means you can drop it directly into a trench without the expense and labor of installing PVC conduit.

Installer’s Insight: If you are wiring a hot tub, check your local codes—most require a "maintenance disconnect" within sight of the tub. #6 URD is perfect for the underground run from the house to that disconnect.

#6 XLP-USE-2/RHH-RHW-2 (Triple Rated)

Estimated Price: $$ (Moderate) Best For: Solar power and seamless outside-to-inside 50-amp runs. This wire is sunlight-resistant for outdoor use and fire-rated for indoor use. It is the "universal" #6 wire that can handle almost any environment.

Installer’s Insight: We use this for solar arrays where the wire is exposed on the roof and then transitions directly into the attic. Since it is fire-rated, you don't need a junction box at the wall—you can run it straight to your 50-amp solar breaker.

#6/3 Aluminum MC Cable (The Armor Choice)

Estimated Price: $$$ (Higher) Best For: Commercial interiors and protected 50-amp runs. Metal Clad (MC) cable features three #6 aluminum conductors and a ground wire wrapped in a flexible, interlocked aluminum armor. This provides superior physical protection compared to standard SER.

Installer’s Insight: If you are wiring a 50-amp circuit in a garage where the cable might be exposed to physical damage, 6/3 MC Cable is a great choice. The armor acts as a built-in conduit, meaning you don't have to spend time bending pipe, but the wire remains protected from nicks and cuts.
