Number 6 wire typically costs about $0.50-$3.50 per conductor foot, depending on copper or aluminum, insulation, and whether it is sold by the foot or in a spool. A typical 100-foot purchase runs roughly $50-$350 for wire alone, while installed costs vary with routing, conduit, access, and electrical requirements.
For most residential projects, conductor material and installation labor create the largest price differences.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| #6 aluminum wire | $0.50/ft | $0.85/ft | $1.40/ft | Insulated, sold by the foot; type and seller affect price |
| #6 copper THHN/THWN-2 | $0.90/ft | $1.55/ft | $2.50/ft | Single conductor; often pulled through conduit |
| #6 bare copper | $1.00/ft | $1.70/ft | $2.80/ft | Grounding or bonding applications where permitted |
| 100-foot wire purchase | $50 | $155 | $350 | One conductor; a circuit may require multiple conductors |
| Installed #6 wire run | $300 | $850 | $2,000+ | Typical short-to-moderate run; conduit and access change total |
What #6 Wire Costs Per Foot and Per Project
For an individual #6 AWG conductor, a practical material budget is $0.50-$3.50 per foot. Aluminum generally occupies the lower end, while copper and specialized insulation can push the price higher. Retail cut lengths, wire color, spool size, and local availability also affect the rate.
A 100-foot circuit is not necessarily a 100-foot wire purchase. A 240-volt circuit commonly needs two ungrounded conductors plus an equipment grounding conductor, and some installations also require a neutral. At three conductors, 100 feet of route can mean about 300 conductor feet before allowing for slack and terminations.
Budget by conductor footage, not just the distance between the panel and equipment.
For example, three #6 copper conductors at $1.55 per foot cost about $465 for 100 route feet, before ground wire, conduit, connectors, fittings, labor, or tax. A comparable aluminum package could cost substantially less, but only if the equipment terminals and applicable electrical rules allow aluminum conductors.
Assumptions: common U.S. retail pricing, one insulated conductor, standard colors, and no unusual shipping or bulk discounts.
How Copper, Aluminum, and Insulation Shape the Quote
Material choice is a major cost lever. Copper #6 wire often costs around $0.90-$2.50 per foot for common insulated building-wire types. Aluminum #6 is often about $0.50-$1.40 per foot. Bare copper may run $1.00-$2.80 per foot, with pricing affected by copper markets and packaging.
Insulation determines where the wire can be used. THHN/THWN-2 is common for conduit installations; its per-foot price generally refers to one conductor, not a complete circuit. USE-2 and other direct-burial-rated conductors may cost more than basic building wire, but the exact permitted installation depends on the product listing and local code.
A lower wire price does not make a material interchangeable with a specified conductor.
Aluminum conductors require terminals listed for aluminum and correct preparation and installation. The applicable ampacity, terminal temperature rating, conductor type, and circuit design matter. A licensed electrician or local inspector can confirm the appropriate wire for the equipment and installation method.
| Wire type | Typical material price | Common price driver | Budget note |
|---|---|---|---|
| #6 copper THHN/THWN-2 | $0.90-$2.50/ft | Color, spool size, copper market | Usually priced per conductor |
| #6 aluminum insulated | $0.50-$1.40/ft | Insulation and listing | Check terminal compatibility |
| #6 bare copper | $1.00-$2.80/ft | Copper price and quantity | Not a substitute for insulated wire |
| #6 USE-2 or similar rated wire | $1.00-$3.50/ft | Listing, insulation, and seller | Confirm permitted use and configuration |
Which Wire Specs and Run Lengths Raise the Price
Wire length, conductor count, and insulation rating determine how much material a project uses. A 50-foot route requiring three conductors needs about 150 conductor feet, plus practical allowances for panel entry, equipment connections, bends, and waste. A 150-foot route with the same configuration can require more than 450 conductor feet.
Longer runs can also change the design. Voltage drop depends on load, conductor material, current, and distance; a designer may specify a larger conductor in some cases. That can increase the price beyond a simple per-foot calculation. It is not safe to choose wire size based only on the price of a roll.
Beyond roughly 100 feet, ask whether the quote accounts for voltage drop and all conductors.
Installation method matters too. A wire pulled through existing conduit may need less new material than a run requiring a new raceway, trench, or wall access. Outdoor or underground work can require a wire type and raceway suitable for the location. A longer route with several bends, tight access, or occupied walls can take more labor even when the footage is modest.
Assumptions: common copper or aluminum conductors, a straightforward route, and no service-panel replacement or major code correction.
How Much Does #6 Wire Installation Add?
Electricians commonly charge about $75-$150 per hour, with regional differences, minimum service fees, and crew size affecting the bill. A straightforward short pull may take 2-4 labor hours, while a longer route through finished walls or new conduit can require 6-12 hours or more. Labor alone can therefore range from roughly $150 to $1,800.
The complete installed price for a typical #6 wire run is often $300-$2,000 or more. A simple 20- to 40-foot connection using an accessible route may fall near the lower end. A 100-foot run with new conduit, difficult access, several conductors, or trenching can reach the higher end, especially when patching or equipment work is included.
Separate wire, conduit, fittings, and labor in the estimate to see what is driving the total.
New conduit can add approximately $2-$10 per linear foot for common materials and installation, with underground or difficult routing potentially costing more. Permit fees may add $50-$300 or more, depending on the jurisdiction and project. Some contractors also apply a minimum charge of about $150-$350 for a small service visit.
For instance, 5 labor hours at $110 per hour equals $550 in labor before materials, permit costs, taxes, or other work. The quote should state whether it includes testing, terminations, labeling, cleanup, and inspection coordination.
Regional #6 Wire Prices Across the U.S.
Wire itself is a commodity, so regional differences in the material price are usually less dramatic than differences in labor and project access. For a comparable installed job, metropolitan coastal markets may run about 15%-35% above a national midpoint. Smaller cities and suburban markets often sit near the middle, while rural areas may be 5%-20% lower for labor but can incur travel or mobilization charges.
A job that might be quoted at $700-$1,100 in a lower-cost market could reach roughly $850-$1,500 in a higher-cost metro area if labor, permitting, and scheduling are comparable. These are planning comparisons, not guaranteed regional rates. Local contractor availability and the need for a trench, lift, or long drive can outweigh broad regional averages.
Compare installed quotes from nearby electricians rather than adjusting wire prices by a national percentage.
Ask each contractor to quote the same conductor material, insulation type, number of conductors, route length, conduit scope, and permit handling. A lower bid may exclude trench restoration, wall repair, testing, or required equipment changes. A higher bid may include those items rather than charge them later as extras.
Pricing can also shift with copper-market changes and distributor inventory. If a project is scheduled weeks out, ask whether the wire price is fixed or subject to material-cost changes before work begins.
When Bare, THHN, or USE-2 Wire Makes Sense
THHN/THWN-2 is often used as individual conductors inside conduit. It is useful for many indoor and outdoor raceway runs, subject to the wire listing and installation rules. Its cost should be compared per conductor foot, and the estimate should specify how many conductors and what colors are included.
USE-2 is designed for certain underground service or direct-burial applications when the product and installation meet applicable requirements. The wire’s listing does not automatically mean it can replace conduit or meet every local rule. Bare #6 copper is commonly used for certain grounding or bonding purposes, but it is not a replacement for insulated circuit conductors.
Match wire type to the route and use before comparing price tags.
For a price comparison, a 100-foot THHN circuit with three conductors at $1.55 per foot has about $465 in conductor material. If a suitable multi-conductor cable is available for the same application, its price may be quoted per cable foot rather than per individual conductor foot. Compare total circuit material and installation requirements, not just the lowest listed unit price.
DIY installation can reduce billed labor but does not remove the need for correct sizing, compatible terminations, safe panel work, and required inspection. Local rules may restrict who can perform electrical work. Incorrect wire or workmanship can create fire and shock hazards, so uncertain designs and panel connections should be handled by a qualified electrician.
Three #6 Wire Quotes for Common Electrical Runs
These examples show how route length, conductor count, and access change a quote. They are planning estimates for typical work, not fixed national prices. Actual totals depend on wire type, local labor, permits, equipment, and whether the existing panel and route are suitable.
| Project example | Material basis | Labor assumption | Estimated total |
|---|---|---|---|
| Garage equipment, 30-ft route | 90 conductor ft at $1.50-$2.20/ft, plus fittings | 3-4 hours at $85-$130/hour | $450-$950 |
| Outdoor equipment, 60-ft route | 180 conductor ft at $1.10-$2.80/ft, plus raceway | 5-7 hours at $90-$140/hour | $850-$1,800 |
| Detached building, 120-ft route | 360 conductor ft at $0.60-$2.50/ft, plus conduit or trench | 8-14 hours at $95-$150/hour | $1,800-$4,500+ |
Long detached-building runs cost more chiefly because of route work, conductor quantity, and trenching.
The garage example assumes an accessible route and no panel upgrade. The outdoor estimate allows for weather-suitable wiring and some raceway work but not extensive excavation. The detached-building range is broad because trench depth, soil, surface restoration, distance, and permit requirements vary considerably.
For each quote, request a written scope listing route footage, conductor count, material type, conduit or trench work, labor hours or labor allowance, permit fees, and exclusions. Confirm whether the contractor will correct unexpected code issues if they are found after opening walls or inspecting the service equipment.
How to Lower a #6 Wire Purchase Without Undersizing
Reducing unnecessary route length is one of the most reliable ways to lower material and labor costs. Ask the electrician whether a shorter path is practical without compromising clearances, protection, or code compliance. Each avoided route foot can save multiple conductor feet when a circuit uses several conductors.
Control the route and scope, but leave conductor sizing and safety decisions to qualified design and installation judgment.
Compare at least two or three itemized estimates using identical specifications. Check whether each includes the same wire material, conductor count, conduit, fittings, permits, testing, and restoration. A quote that uses aluminum may be less expensive than copper, but it is only a valid comparison if the equipment is listed for it and the design is appropriate.
Buying a larger spool can reduce the per-foot price, but only when the remaining wire will be useful and storage is practical. For a one-time job, compare the delivered price of the needed cut length with a spool, including shipping and unused material. Avoid paying for premium insulation, a larger conductor, or a full panel upgrade unless the project design or inspection requires it.
Schedule nonurgent work during a contractor’s less busy period if timing is flexible, and complete simple access preparation only when the electrician confirms it is safe and useful. Do not open walls, dig, or disconnect electrical equipment without approval. A clear path can save labor, but unsafe preparation can create damage and added charges.
