Process
How Does the Process Work?
Call and Describe Your Setup
Tell the electrician what you drive, where you park, and where your panel sits. Photos of the panel label help.
Site Check and Written Quote
The electrician looks at your panel and the path to the parking spot, then gives you a written quote.
State Electrical Permit
Your electrician buys the state electrical permit before the work starts.
Install the Circuit and Charger
A new breaker, wire, and the charger or receptacle go in. The charger is set to match the circuit size.
State Inspection
Your electrician requests the inspection. A state inspector checks the work before the job is closed out.
Cost
What Affects the Cost?
Distance From the Panel
A charger next to the panel needs a short run. A detached garage or far wall needs more wire and conduit.
Panel Space and Capacity
A full panel or a small service can call for a subpanel, a load management device, or a panel upgrade.
Charger Choice
Smart features, cable length, and outdoor use all change the hardware price.
Circuit Size
A 48 amp charger on a 60 amp circuit needs heavier wire than a 32 amp charger on a 40 amp circuit.
Wall and Finish Work
Fishing wire through finished walls or a basement ceiling takes more labor than an open garage wall.

Call (615) 235-9332What Does the Code Require for a Level 2 Charger?
Tennessee enforces the 2017 NEC, as of October 2026. Article 625 covers EV charging equipment. Section 625.40 calls for each EV outlet to sit on its own individual branch circuit, so the charger does not share with a dryer or a range.
Charging counts as a continuous load. Under 625.41, the breaker must be sized at 125% or more of the charger's maximum current. That is why a 32 amp charger goes on a 40 amp circuit and a 40 amp charger goes on a 50 amp circuit.
Before adding the circuit, the electrician runs a load calculation under Article 220. The charger counts at its full nameplate amps as a continuous load. If the numbers do not work, there are options, and an EV readiness inspection can sort them out before you buy a car.
Electrical permits in Brentwood come from the State of Tennessee through the State Fire Marshal's Office. A licensed electrician buys the permit and requests the state inspection. For jobs under $25,000, that is often a Limited Licensed Electrician (LLE).
Charging at Home in Brentwood
Two utilities serve Brentwood: NES and Middle Tennessee Electric. Check your power bill to see which one serves your address. MTE members can apply for a $50 EV Ready bill credit toward Level 2 wiring. NES does not list a home charger rebate that we could confirm. See rebates and incentives for the full picture.
Newer, larger Brentwood homes often have 200 amp service, while some older homes may have smaller panels. The electrician checks either way. Big lots can mean long runs to a side-entry or detached garage, which adds wire and labor.
Neighbors in Franklin and Nolensville face similar choices. If you charge at work too, the commercial and workplace charging page explains how businesses add ports.
Hardwired or Plug-In: Which Fits Your Garage?
A hardwired charger connects straight to the circuit and has no plug to wear out. A plug-in charger can leave with you when you move. The NEMA 14-50 outlet page lays out the tradeoffs. If a charger already on your wall stops working, see charger repair and troubleshooting.

What Size Breaker Does a Level 2 Charger Need?
