10 gauge wire cost ranges from about $0.30 to $3.50 per foot for the wire alone, depending on cable type, copper prices, and purchase quantity. A typical 100-foot purchase costs roughly $50-$220, while a professionally installed circuit may cost $300-$1,200 or more because labor, access, and electrical work can exceed the material bill.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 10 AWG THHN copper wire | $0.30/ft | $0.55/ft | $0.90/ft | Single conductor; conduit usually priced separately |
| 10/2 NM-B cable | $1.20/ft | $1.80/ft | $2.60/ft | Indoor residential cable with ground |
| 10/2 UF-B cable | $1.50/ft | $2.40/ft | $3.50/ft | Direct-burial-rated cable |
| 100-foot installed run | $300 | $650 | $1,200 | Typical accessible route; panel work may add cost |
10 Gauge Wire Prices by Cable Type and Length
Retail prices vary with brand, copper market conditions, insulation rating, and whether the wire is sold by the foot, spool, or coil. The estimates below reflect common U.S. retail pricing for copper products; aluminum 10 AWG may cost less, but it is not an automatic substitute for copper in every application. Buyers should match the conductor and cable listing to the circuit design and local code.
For a typical indoor project, 10/2 NM-B often costs $120-$260 per 100 feet before tax. A 10/3 cable, which has an additional insulated conductor, commonly runs $2.00-$3.80 per foot. Single-conductor THHN is less expensive per foot, but a project may require multiple conductors, conduit, fittings, and ground wire, so comparing just one THHN conductor with a complete cable is misleading.
| Product | Low | Average | High | Typical purchase |
|---|---|---|---|---|
| 10 AWG THHN copper | $0.30/ft | $0.55/ft | $0.90/ft | 500-foot spool, roughly $150-$450 |
| 10/2 NM-B copper | $1.20/ft | $1.80/ft | $2.60/ft | 100 feet, roughly $120-$260 |
| 10/3 NM-B copper | $2.00/ft | $2.80/ft | $3.80/ft | 100 feet, roughly $200-$380 |
| 10/2 UF-B copper | $1.50/ft | $2.40/ft | $3.50/ft | 100 feet, roughly $150-$350 |
Assumptions: Standard copper conductors, ordinary retail availability, and no sales tax or delivery charge. Online bulk pricing can fall below these ranges, while short cut lengths from a local store may carry a higher per-foot price.
What Adds to a 10 AWG Wire Quote
A complete electrical quote may include more than the wire. For conduit installations, the estimate can include conduit, bends, boxes, connectors, supports, and a grounding conductor. A cable installation may need staples, clamps, junction boxes, and protective plates where framing creates a risk of screw or nail damage.
Installation labor and access usually create the largest difference between a wire-only price and a finished-project quote. A straightforward exposed route through an unfinished basement can be relatively quick; fishing cable through finished walls, drilling several floors, or trenching to an outbuilding takes substantially longer. A permit, inspection, or panel modification may also be necessary depending on the work and local rules.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Wire and cable | $50 | $180 | $380 | 50-100 feet, depending on product |
| Conduit and fittings | $40 | $140 | $350 | Route-dependent materials |
| Electrician labor | $150 | $450 | $900 | About 2-8 hours at $75-$150/hour |
| Permit and inspection | $0 | $100 | $350 | Varies by jurisdiction and project |
| Removal or trenching | $0 | $150 | $700 | Only when existing work or burial is involved |
Not every job needs each item. For example, an electrician replacing a short, accessible section may not need new conduit or a permit, while a new outdoor circuit can involve trenching, weather-rated boxes, and inspection. Ask whether the quote includes materials, cleanup, permit charges, and any panel work.
How Copper, Insulation, and Run Length Change the Price
Copper content and cable construction are the first pricing differences. A single THHN conductor uses less material per foot than a multi-conductor cable, but circuits need the required hot, neutral, and grounding conductors. UF-B cable costs more than ordinary indoor NM-B because its construction is intended for wet locations and direct burial under applicable installation rules.
Longer runs increase both material cost and the chance of added installation work. A 50-foot 10/2 NM-B purchase at $1.20-$2.60 per foot is about $60-$130; 200 feet is about $240-$520 before labor. Large coils may reduce the unit price, although leftover cable has value only if it can be used on a later project.
Run length can also affect electrical design. For a 120-volt circuit carrying 20 amps, a long run approaching 100 feet may prompt an electrician to evaluate voltage drop and the equipment requirements. At 240 volts, the same load has different conditions. Wire gauge alone does not establish a safe circuit: breaker size, load, conductor material, temperature rating, installation method, and local code all matter.
A 10 AWG conductor is commonly used in 30-amp circuits, but that does not mean every 10 gauge installation should use a 30-amp breaker. The allowable ampacity depends on the conductor and termination ratings and other code conditions. Appliances may also specify a particular circuit and wire configuration, so the manufacturer’s instructions and electrician’s design should govern.
When Does 10 Gauge Wire Need Professional Installation?
Replacing a short, like-for-like cable segment can be a modest job, but new circuits and panel connections present greater safety and code risks. A 240-volt appliance circuit, outdoor run, garage feed, or circuit requiring a new breaker should be evaluated for load, grounding, protection, and permit requirements. Local rules differ, and some jurisdictions restrict electrical work to licensed professionals.
Scope, not just wire gauge, determines whether the job needs a permit or specialized work. A 25-foot run through an open basement may be simpler than a 15-foot route through finished masonry. A 50-foot outdoor route may require burial-rated cable or a conduit system, suitable depth and protection, weather-resistant fittings, and inspection. The contractor should identify these requirements in the estimate rather than leave them as surprise charges.
Before accepting a quote, confirm the circuit’s intended load and equipment, the proposed cable type, and whether the price includes a breaker, boxes, and final connections. If the work involves a panel, ask whether the panel has capacity and whether any upgrades are excluded. A low quote that covers only cable installation may not include the complete circuit or required inspection.
10 Gauge Wire Labor Rates for Common Runs
Electricians commonly charge about $75-$150 per hour, with higher rates possible in expensive metro areas or for emergency work. Small jobs may have a minimum service charge of $100-$250, even when the actual installation takes less than an hour. Travel, diagnosis, and setup can make a short wire repair cost more per foot than a larger project.
Labor time depends heavily on whether the route is open, concealed, or outdoors. A simple accessible 25- to 50-foot run may take 2-4 hours; routing through finished walls or multiple floors can take 4-8 hours or longer. A buried run can require excavation equipment or manual trenching, which may be priced separately.
For example, four hours at $100 per hour equals $400 in labor before materials, permits, or service fees. An estimate of $600-$900 for an accessible new circuit might be reasonable when it includes wire, boxes, a breaker, and testing; a more complex route can exceed $1,200.
Ask whether labor is billed hourly or as a fixed project price. A fixed bid can make budgeting easier when the scope is clearly defined, while hourly pricing may be appropriate for troubleshooting or uncertain concealed conditions. Confirm how the electrician handles extra work discovered after opening walls or accessing the panel.
Compare 10/2 NM-B, THHN, and UF-B Prices
These products are not interchangeable simply because each contains 10 AWG conductors. NM-B is commonly used in permitted dry indoor locations. THHN is an individual conductor type generally installed in conduit where required. UF-B is designed for wet-location and direct-burial applications when installed according to code. Product labels and the installation plan matter more than a low unit price.
Compare the cost of a complete installed wiring method, not one conductor against a finished cable. THHN at $0.30-$0.90 per foot may require two or more insulated conductors, a ground, conduit, and fittings. A 10/2 cable already groups insulated conductors and a ground, while UF-B offers a different rating and construction for outdoor use.
| Type | Wire price | Common use | Cost detail |
|---|---|---|---|
| 10/2 NM-B | $1.20-$2.60/ft | Indoor dry locations | Complete cable with ground |
| 10 AWG THHN | $0.30-$0.90/ft per conductor | Conduit installations | Multiple conductors and conduit add cost |
| 10/2 UF-B | $1.50-$3.50/ft | Outdoor or direct-burial applications | Trenching and fittings may be extra |
Where U.S. Buyers Pay More for 10 Gauge Wire
Material prices are often similar across regions when buyers compare the same brand and product, but local stock, shipping, and contractor rates can widen the difference. In high-cost coastal metros, electrician labor may run about 15%-35% above a national baseline. Smaller rural markets may have lower hourly rates but higher travel charges or fewer suppliers carrying specialty cable.
Installed prices can vary more by labor market and access than by the wire itself. A 100-foot accessible indoor circuit that costs $450-$850 in a lower-cost market might reach $600-$1,100 in a high-cost metro, particularly if work is scheduled during a busy period. These are planning ranges, not fixed regional tariffs.
Shipping can be significant for heavy coils, and some retailers charge a cutting fee for custom lengths. Compare the delivered price, not just the listed per-foot rate. For contractor quotes, check whether the price includes local permit fees and disposal, since those charges differ by city and project scope.
Ways to Lower a 10 Gauge Wire Purchase and Install Bill
Measure the route carefully and add a reasonable allowance for bends, terminations, and routing changes before ordering. Buying a 500-foot spool may lower THHN cost per foot, but it is not economical if the project needs only 40 feet and the remainder will sit unused. For cable sold by the foot, compare the price of a measured cut with a 50- or 100-foot coil.
Keeping the route accessible and the scope complete can reduce labor without compromising electrical safety. If walls are already open during a renovation, arranging the circuit work before drywall installation can reduce fishing and patching charges. Clearing access to the panel and work area also saves setup time.
Request two or three itemized quotes that specify wire type, length, breaker, conduit or cable method, permit, and testing. Comparing a quote for THHN in conduit with one for NM-B cable is useful only if both methods are suitable for the location and deliver the same scope. A low bid that omits a required ground, panel work, or inspection is not a like-for-like price.
Avoid paying for a higher-grade cable or oversized design unless the conditions require it. At the same time, do not substitute a smaller conductor, change a breaker, or choose an unsuitable cable solely to save money. The electrician should verify the equipment’s requirements and applicable code before materials are purchased.
