If you’re running larger appliances, you’ll need 30- to 50-amp circuits.
Expect to pay about $550 to $970 for just the labor of this project.
This project requires an electrical inspection, which runs between $100 and $400.
You may need to redrywall and paint after, which is a separate job and cost.
Upgrading your electrical panel could cost an additional $500 to$2,000.
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.
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.

Circuit breaker
$10 to $30
Junction box

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:
Unless you are a licensed electrician, you should always hire a professional electrician near you to handle electrical work. Working with electricity is dangerous, and if you don't know what you're doing, you could get hurt or start an electrical fire.
Plus, this project could jumpstart other necessary projects related to your electrical panel or wiring. In this case, it’s best to stick with a trained, licensed, and insured electrician who will complete the job fast and to code.
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 season are usually slower for electricians, meaning they may 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.

Frequently Asked Questions
If you've ever tried to run your dishwasher while drying your hair, you’ll understand why dedicated circuits are essential for preventing blown fuses. Appliances that require more electricity than the circuit can handle could blow fuses, trip breakers, overheat, and risk an electrical fire.
Having a dedicated circuit ensures that your appliance gets the current it needs without overloading the other circuits in your home.
Appliances in your home that need dedicated circuits include:
Refrigerators and chest freezers
Electric ranges, microwaves, and toaster ovens
Dishwashers and garbage disposals
Washers and dryers
Heating and air conditioning units
Hot tubs, saunas, and water pumps
Sump pumps
Central vacuums
Moving an outlet usually costs between $25 and $300. The amount you'll pay depends on the type of outlet and the condition of the walls in your home. Exposed walls without drywall and insulation are the easiest for electricians to work on, but finished walls that will require repair afterward can drive up the cost.
Changing from a two-prong to a three-prong outlet is a pretty basic project that usually costs around $20 to $50. If you have a grounded fuse box, your electrician should be able to do the task quickly and easily; however, if they have to upgrade your electrical panel or ground the box, the cost could increase.
