How Much Does It Cost to Install a Dedicated Circuit? [2025 Data]

The cost to install a dedicated circuit is about $700 on average, though homeowners can expect to spend between $570 and $1,100. Dedicated circuits are necessary to power major appliances, such as a refrigerator or an oven, or to install a dedicated line in your garage for power tools and lighting.

You likely need multiple dedicated circuits in your home to power your appliances. Let’s review how to budget for adding a dedicated circuit to your home or garage, as well as when to hire a professional electrician to tackle this task.

How to Calculate the Cost of Installing a Dedicated Circuit

To determine how much it will cost to install a dedicated circuit in your home, follow these steps:

• Get multiple quotes from electricians: Solicit price quotes from at least three local electricians, asking specifically for their material and labor costs. 

• Determine electrical inspection cost: You will likely need an electrical inspection post-installation to ensure everything is up to code. Contact local electricians or services that conduct these inspections to determine the cost.

• Consider the cost of add-on services: If you need other electrical service completed in tandem with installing a dedicated circuit, add that cost into your total price.

Dedicated Circuit Cost Factors

The cost of a dedicated circuit depends on several factors, including type of circuit, materials, and local labor costs.

Type 

There are two basic types of dedicated circuits in your home, 20-amp and 30 to 50 amp. The cost to install these types of dedicated circuits is comparable at around $700 on average. 

Smaller appliances, like toasters, stand mixers, and countertop appliances use 20-amp circuits. Larger appliances like dryers, stoves, ovens, and water heaters use 30- to 50-amp circuits. You'll most likely be looking at installing a 30- to 50-amp circuit unless you're short on regular outlets in your kitchen or other places you need to install outlets.

Materials

The materials to install a dedicated circuit usually run around $100 to $150. Materials that your electrician will need to install a dedicated circuit include circuit breakers, junction boxes, connectors, fittings, fasteners, and other things. 

Labor

You can expect to pay around $550 to $970 for labor to install a dedicated circuit. The cost to hire an electrician is usually $50 to $100 per hour for labor, and electricians typically charge more for the first hour, about $150. The labor for installing a dedicated circuit includes:

• Shutting off power

• Cutting mounting holes

• Mounting the electrical boxes

• Adding a new circuit breaker

• Securing and connecting wiring

How much you can expect to pay to have a local professional electrician install a dedicated circuit varies depending on your location. Here's a breakdown of average costs for some cities around the U.S.

• New York: $890–$1,090

• Des Moines, IA: $610–$740

• Los Angeles: $710–$870

• Seattle: $715–$875

• Miami: $570–$700

• Topeka, KS: $600–$740

• Philadelphia: $720–$880

• Santa Fe, NM: $645–$790

• Detroit: $670–$820

How Much Does It Cost to Install a 15–20 Amp Dedicated Line in a Garage?

If you’re adding a dedicated circuit in your garage, you may only need a 15- to 20-amp to use your tools. You can expect to pay $250 to $900 for dedicated circuit installation in your garage, with an average cost of $650. Your final price will depend on how far the new circuit is located from the main electrical panel, labor costs, and overall project complexity. Consult a local electrician with experience outfitting garages to get an accurate estimate.

Additional Cost Factors

There are some other potential costs that you could be looking at when installing a dedicated circuit. Those can run from $500 to upwards of $8,000 and include:

• Upgrading or replacing electrical panel: $500–$2,000 per panel

• Opening walls and running wire: $600–$6,000 

• Removing or repairing any framing or system: $7 to $16 per square foot

• Permitting or inspection fees: $10–$500

Why You Should Hire an Electrician to Install a Dedicated Circuit

To be clear, it’s always best to hire a professional electrician for work that involves wiring. While DIYers can certainly handle smaller tasks, such as replacing a light fixture, anything that involves adjusting or installing electrical wires should be left to an experienced and licensed professional electrician. 

Here’s why it’s ideal to hire an electrician

A dedicated circuit installation is a complex project that should be handled by an experienced pro electrician. Here are a few reasons to hire an electrical pro:

• The labor and tools needed are often beyond the scope of a DIYer’s resources.

• A pro electrician understands how to do the work safely and in compliance with building code.  

• The work will be done faster and more efficiently by a pro.

• The electrician will also be able to spot any other issues in your wiring and make recommendations for repairs or additional installations.

How to Save Money Installing a Dedicated Circuit

Here are a few ways you can save on a dedicated circuit installation:

• Hire out-of-season: Many home projects are completed in the spring and summer, which means fall and winter are typically slower for electricians, allowing them to charge less.

• Get multiple quotes: With any type of renovation or upgrade, getting multiple quotes from professional electricians can help you find a rate that fits your budget while still getting the job done well.

• Be prepared: If you need to open walls or replace old wiring, it’s helpful to have an idea of where and how the electrician should do that before they start work. Otherwise, you may need to unexpectedly open or reframe a wall, adding to the total project cost.
