Running a 240V line in a U.S. home typically costs $300-$1,500, with many straightforward installations near $700. The final price depends on circuit amperage, distance from the electrical panel, wall access, and whether the panel needs additional capacity or a service upgrade.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New 240V circuit | $300 | $700 | $1,500 | Typical accessible route, no panel upgrade |
| Per-foot wiring allowance | $8 | $15 | $30 | Installed estimate; route and wire size affect rate |
| Panel or service work | $500 | $1,500 | $4,000+ | Only when capacity or equipment requires it |
| Permit and inspection | $50 | $150 | $400 | Varies by local jurisdiction |
What a typical 240-volt circuit installation costs
A basic 240V circuit for a dryer, range, or small workshop tool often costs $300-$800 when the panel has room and the cable can run through an unfinished basement or open garage. A longer route, concealed wiring, or higher-capacity appliance can bring the total to $800-$1,500 or more.
Most quotes cover a dedicated breaker, correctly sized wiring, installation, and basic testing. The estimate assumes ordinary residential access and no service-panel replacement. A new EV charger circuit or large appliance may need heavier cable and a 40- to 60-amp breaker, increasing material and labor costs.
Assumptions: Standard U.S. residential wiring, typical contractor labor, normal access, and no major panel work.
How wire, breaker, labor, and access shape the invoice
Contractors commonly price a 240V circuit as a complete job rather than a simple cable charge. Materials vary with amperage and wire type, while labor can rise sharply when walls, ceilings, or finished floors must be opened and repaired.
| Quote component | Typical price | What changes it |
|---|---|---|
| Copper cable and fittings | $2-$10 per ft | Gauge, conductors, conduit, and route |
| Breaker and installation parts | $40-$250 | Panel brand, breaker type, and amperage |
| Electrician labor | $75-$150 per hour | Region, crew size, and access |
| Wall opening and patch allowance | $100-$600 | Finish type and repair scope |
| Permit and inspection | $50-$400 | Local rules and project value |
Labor hours multiplied by the hourly rate often determine whether a short run stays affordable. Some electricians also charge a $75-$200 service-call or minimum-job fee, which matters for small installations.
Which amperage and cable distance raise the quote
A 20-amp circuit for a small appliance generally costs less than a 50-amp range or a 60-amp EV charger circuit because higher amperage requires larger conductors and compatible equipment. The appliance’s installation instructions determine the required breaker and wire; a contractor should not size a circuit by outlet appearance alone.
Distance also matters. A 25-foot accessible run may fit a basic quote, while a 75-foot route can add hundreds of dollars in cable, labor, and voltage-drop planning. Runs over 100 feet, outdoor conduit, detached garages, and trenching can require a site-specific estimate.
Ask whether the quote states the circuit amperage, wire gauge, route length, and equipment connection. These details make competing bids easier to compare and help prevent an undersized or incomplete installation.
How long an electrician needs to run a 240V circuit
An accessible installation often takes 2-5 hours, including mounting the outlet or disconnect, routing cable, installing the breaker, and testing. A concealed route through finished walls may take most of a day, especially if drywall repair or multiple access openings are needed.
Electricians may send a second worker for long cable pulls, attic work, or heavy equipment. A two-person crew can increase the hourly labor total but may shorten the job. Confirm whether patching, painting, appliance connection, and inspection coordination are included.
Get the expected labor hours and included finish work in writing. A low bid that excludes drywall repair can cost more after the electrical work is complete.
Does a garage or finished-wall route cost more?
An exposed run in an unfinished basement or garage is usually cheaper than routing cable inside finished walls. Surface-mounted conduit may keep labor down, though local code, appearance, and physical protection requirements can affect whether it is acceptable.
Outdoor runs, detached buildings, and underground routes add weather-rated materials, conduit, and sometimes trenching. Trenching may cost roughly $5-$20 per linear foot, excluding unusual rock, concrete, or landscaping restoration. A long detached-garage feed may need a subpanel rather than a simple branch circuit.
Route complexity can matter as much as the outlet location. Ask the electrician to price both a compliant surface route and a concealed route when appearance is important.
Three 240V line quotes for common household jobs
These examples illustrate how scope changes the total; local labor rates and equipment requirements can shift each estimate. They assume the existing panel has adequate capacity.
| Job example | Scope | Estimated total |
|---|---|---|
| Electric dryer | 30-amp circuit, 20-ft accessible run | $350-$700 |
| Garage EV charger | 50-amp circuit, 35-ft route, charger excluded | $650-$1,400 |
| Workshop equipment | 40-amp circuit, 70-ft concealed route | $1,000-$2,200 |
Equipment is often separate from circuit installation. A charger, outlet, disconnect, load-management device, or appliance hookup may add to the quote, so check the itemized scope.
When panel upgrades and permits add to price
If the panel has no open breaker spaces, an electrician may install approved tandem breakers when allowed, add a subpanel, or replace the main panel. A subpanel can add about $500-$1,500; a full panel replacement often costs $1,500-$4,000 or more, depending on service size and required code work.
Permits commonly range from $50-$400, but local fees and inspection rules differ. Older homes may also need grounding, bonding, or other corrections discovered during inspection. Utility coordination or a service upgrade can push a project beyond the usual circuit budget.
Request a load calculation before accepting an estimate that assumes the panel can support the new appliance. It can reveal capacity limits before installation begins.
How to lower the cost of a new 240V line
Place the appliance near the panel when practical, choose an accessible cable route, and clear stored items from the work area before the electrician arrives. If several circuits are planned, ask whether completing them during one visit reduces travel and setup charges.
Compare at least two itemized quotes with the same amperage, wire route, outlet or disconnect, permit scope, and finish work. Avoid choosing a lower price that omits required materials or inspection. Do not reduce wire size, skip a permit where required, or install a circuit beyond personal skill; 240V work presents shock and fire risks.
The safest savings usually come from simpler routing and a clearly defined scope, not cutting electrical specifications. A repair or load-management option may also cost less than a panel upgrade when a qualified electrician confirms it meets the appliance instructions and local code.
