How Much Does It Cost to Install a Dedicated Circuit?
A dedicated circuit typically costs $150 to $700 to install. A standard 120V circuit with panel space runs $150–$400, while a heavier 240V circuit (for a dryer, range, or EV) runs $250–$700. If your panel is full, add $500–$2,000 for a subpanel or upgrade.
A dedicated circuit serves one appliance directly from the panel, so it never has to share power. Many large or sensitive appliances require one by code. Here's what it costs and why you might need one.
Typical Cost by Circuit Type
| Circuit | Typical Cost |
|---|---|
| New 120V circuit (panel has space) | $150 – $400 |
| New 240V circuit (dryer, range, EV) | $250 – $700 |
| Long wire run / difficult access | Adds $100 – $300 |
| If a subpanel or upgrade is needed | Add $500 – $2,000 |
Typical U.S. estimates; cost varies by amperage, wire distance, and panel capacity. Your electrician provides a firm quote.
When You Need a Dedicated Circuit
- Large appliances — dryer, range, oven, water heater, AC
- EV chargers and workshop equipment
- Microwaves, dishwashers, and garbage disposals (often code-required)
- Space heaters or window AC units that trip shared circuits
- Sensitive electronics needing steady, isolated power
Why it matters: a dedicated circuit prevents overloads and nuisance breaker trips, and it's often required by code for high-draw appliances. Sharing a circuit with a big appliance is a common cause of tripping — and a fire risk.

Frequently Asked Questions
What is a dedicated circuit?
A circuit that serves a single appliance or outlet directly from the panel, so it doesn't share power with anything else. This prevents overloads on high-draw devices.
Do I need a permit for a new circuit?
Usually yes. Adding a new circuit typically requires a permit and inspection. A licensed electrician handles this as part of the work.
Can I add a circuit if my panel is full?
Sometimes, using tandem breakers or a subpanel. If the panel is at capacity, you may need a subpanel or a panel upgrade first — your electrician will confirm.
