What is a dedicated circuit?

A dedicated circuit is an electrical circuit that serves only one appliance or device, with its own breaker in the panel. It prevents the circuit from being overloaded by other devices and ensures the appliance receives consistent, reliable power. Major appliances like refrigerators, dishwashers, HVAC units, and EV chargers require dedicated circuits by code.

Do I need a permit to add a circuit in Murfreesboro, TN?

Yes. Adding a new circuit in Murfreesboro requires an electrical permit from the city or Rutherford County, depending on your jurisdiction. Murfreesboro Pro Electric handles all permit applications and coordinates the required inspection so the work is fully code-compliant and documented.

Which appliances require a dedicated circuit?

The National Electrical Code (NEC) requires dedicated circuits for refrigerators, dishwashers, garbage disposals, microwave ovens, washing machines, electric dryers, electric ranges and ovens, HVAC units, water heaters, EV chargers, and any other high-draw appliance. Running these on shared circuits can trip breakers repeatedly and create fire hazards.

Electrician Running New Dedicated 240V Appliance Circuit in Murfreesboro TN

Dedicated Circuit Installation in Murfreesboro, TN

Running too many devices on a single circuit — or plugging a high-draw appliance into a shared outlet — is one of the most common causes of tripped breakers, overheated wiring, and electrical fires in Murfreesboro homes. A dedicated circuit provides a direct, protected electrical path from your panel to a single device, ensuring reliable power and eliminating the risk of overload.

Murfreesboro Pro Electric installs new dedicated circuits for any application — from adding an outlet for a new kitchen appliance to running a 240V circuit for an EV charger or hot tub. Every circuit we install is permitted, inspected, and fully code-compliant.

Dedicated Circuit FAQ

How long does it take to add a new circuit?

Most dedicated circuit installations are completed in 2–4 hours, depending on the distance from the panel to the outlet location and wall/ceiling construction. Runs through finished walls require more time than open-stud construction. We provide a time estimate as part of the free quote.

Will adding a circuit damage my walls?

Our electricians use low-impact fishing techniques to run wire through finished walls with minimal drywall damage. When attic or basement access is available, we route wire through those spaces with no visible wall impact. Any small access holes required are patched as part of our standard service.

My panel is full — can I still add a circuit?

In many cases, yes. Options include installing tandem (slim) breakers if your panel supports them, or adding a sub-panel. If your panel is at or near its amperage capacity (common in older 100A panels), a panel upgrade may be the best long-term solution. We evaluate all options during the free estimate.
