How Much Does It Cost to Install a Dedicated Circuit in 2025?

This article was created using automation technology and thoroughly fact-checked and edited by HomeAdvisor Editor Ryan Noonan.

On average, homeowners invest between $570 and $1,000 for the cost to install a dedicated circuit, with most paying an average of $700. Various factors influence the final price, including the type of circuit needed, the complexity of installation, and your geographic location.

A dedicated circuit delivers electricity to a single appliance or outlet, helping prevent circuit overloads and reducing fire hazards. When you need to power major appliances like refrigerators or ovens, these specialized circuits become essential for electrical safety.

Dedicated Circuit Installation Cost Factors

Understanding what affects the cost of installing a dedicated circuit can help you budget appropriately for this important electrical upgrade.

Type of Circuit

Dedicated circuits come in different amperage ratings depending on what appliance or area they'll serve. The two primary types are 20-amp circuits and 30 to 50 amp circuits.

Both types of circuits cost approximately the same to install, at $700. The similarity in cost occurs because the installation process is largely the same, though material costs may vary slightly.

Size

The physical distance between your electrical panel and where the new circuit will terminate affects both labor time and material requirements. While the reference cost guide doesn't provide specific breakdowns by size, longer distances require more wire and labor time.

Frequency

Most dedicated circuit installations are one-time projects. However, if you're planning multiple installations, some electricians may offer a discount on the per-circuit cost. This section refers to how bundling multiple circuit installations can potentially reduce your overall expense.

Materials

The components needed for a dedicated circuit installation include circuit breakers, junction boxes, connectors, and wiring. The average cost for materials is between $100 and $150 for a standard dedicated circuit installation.

Labor

Professional electricians charge between $50 and $100 per hour for their services. The first hour often costs more, averaging $150, to account for travel time and initial setup. Labor represents the largest portion of your dedicated circuit installation cost, ranging from $550 to $970.

The labor process includes:

• Shutting off power

• Cutting mounting holes

• Mounting electrical boxes

• Adding a new circuit breaker

• Securing and connecting wiring

Location

Where you live significantly impacts installation costs due to varying labor rates and permit requirements across the country.

Cost of Common Project Add-Ons

Depending on your home's electrical system and the complexity of the installation, installing a dedicated circuit might incur additional expenses.

Ongoing Project Costs

While installing a dedicated circuit is primarily a one-time expense, there are some continuing considerations to keep in mind.

Maintenance

Dedicated circuits require minimal maintenance. Occasional visual inspections of outlets, connections, and breakers can help identify potential issues before they become problems. Professional electrical inspections cost between $100 and $400 and are recommended periodically to ensure system safety and code compliance.

Operating Costs

A dedicated circuit doesn't add any direct operating costs beyond the electricity consumed by the appliances connected to it. The circuit itself doesn't use electricity when appliances are not in operation.

Repairs

If repairs become necessary, costs will vary based on the specific issue:

• Replacing a circuit breaker: $10 to $30 plus labor

• Junction box repairs: $10 to $20 plus labor

• Rewiring: Part of the $600 to $6,000 range for running wire, depending on complexity and access

Emergency electrical repairs often come at premium rates, sometimes 1.5 to two times the standard rate.

Insurance

Properly installed dedicated circuits by licensed electricians help ensure your electrical system meets code requirements. While the reference guide doesn't specifically mention insurance impacts, professional installation documentation is important for maintaining home warranty and insurance coverage.

Budgeting for the Cost to Install a Dedicated Circuit

Consider these cost-saving tips to make your electrical project more budget-friendly:

• Compare multiple quotes: Reach out to several local licensed electricians to find competitive pricing for your project.

• Consider scheduling strategically: Fall and winter months may offer better rates when electricians are less busy.

• Prepare access points: Clear the work area and ensure easy access to reduce labor time and costs.

• Plan for wall repairs: If your installation requires opening walls, be prepared for additional expenses or consider handling non-electrical repairs yourself.

• Bundle multiple circuits: If you need several dedicated circuits, installing them simultaneously can reduce the per-circuit cost.

• Discuss budget constraints: Most electricians can suggest cost-effective solutions that meet your needs while staying within budget.

• Research permit requirements: Understanding local permit costs in advance helps avoid surprise expenses.
