Upgrade or Load Management
Sharing capacity is a smaller job than a new service.
Residential
You need a panel upgrade for EV charger work in Collierville only when a load calculation shows your service cannot carry the new circuit. Many homes with 200 amp service have room. Older or smaller panels may need a larger service, or a load management device that shares capacity with other circuits.
A panel check makes sense if any of these fit your home.
Scope depends on what the load calculation shows. Typical items include:
Call (901) 555-0100 to speak with a local electrician. Have your panel size and charger model handy.
Your electrician adds up the connected load and checks whether the existing service can carry the charger.
You weigh a service upgrade against load management or a lower charger setting.
The electrician gives you a written quote, pulls the permit with the Town, coordinates any MLGW work, and schedules the inspection.
Scope follows the load calculation. Common drivers:
Sharing capacity is a smaller job than a new service.
A worn panel may need replacing even with spare capacity.
A new meter base, mast, or service conductors adds labor and material.
Panel placement affects the charger run and the Town's 15 foot rule.
The Town of Collierville sets these, and they are part of your quote.
As adopted by the Town of Collierville, the 2017 NEC with Town amendments is the code in force as of October 2026. Your electrician confirms the edition when the permit is pulled.
The Town's amended 220.1(a) says whoever adds load must confirm the service, feeders, and equipment are sized for the total connected load. Amended 220.10 wants branch-circuit load calculations with or before the Rough Electric inspection, with an exception for some one- and two-family layouts. EV charging is a continuous load under NEC Article 625, so the circuit is sized at 125% of the charger's current.
Amended 110.5(a) bars aluminum conductors inside one-, two-, and multi-family dwellings, except as Article 334 allows. Under amended 334.10, aluminum or copper-clad aluminum Type NM cable must be concealed in metal conduit or an approved raceway.
The Town's Building & Codes Division requires a state or county licensed contractor for electrical work. GFCI protection follows the edition your permit office enforces, and your electrician applies it. See permits and inspections for the Town's process.
Summer heat keeps central air running for hours on the same panel as your charger. Newer subdivisions often have larger service, while older homes near the historic Town Square may not. Planning a Level 2 home charger on a tight panel? An EV readiness inspection answers the capacity question first.

Not always. A load calculation decides it. Some 150 amp homes can carry a 40 amp charger, while some 200 amp homes with heavy electric loads cannot.
It watches your home's total draw and slows or pauses the charger when other loads peak. Smart panels and circuit sharing work in a similar way, often in place of a service upgrade.
Yes, when the service size changes. The meter and service drop belong to MLGW, so your electrician coordinates the disconnect and reconnect with the utility.
MLGW's home-charger incentives, if any, change over time. Confirm the current offer at mlgw.com or with MLGW before you buy. Our rebates and incentives page tracks what we have verified.
Distance, wall type, and charger amperage drive it. See installation cost factors and our EV charging FAQ.
