One EV charger is a straightforward project for many North Georgia garages. Two chargers—or one charger shared by two drivers with heavy commutes—raises questions about panel space, service size, and whether both cars charge on the same night.
Nix Electrical installs Level 1 and Level 2 EV chargers across our service areas. This guide helps two-car households gather facts before the first site visit.
Start with how each car is used
- Daily miles per driver
- Whether both cars must be full every morning
- Whether cars park in the same garage, driveway, or split locations
- Charger specs and vehicle onboard limits for each car
Level 1 charging on an existing outlet may work for a short commute on one car while the other uses Level 2. Two Level 2 units pulling full current simultaneously is a different electrical conversation.
Panel and service size matter more than brand
Photos of your panel directory and service rating help us estimate whether two dedicated circuits fit—or whether a panel upgrade belongs in the plan. Kitchen expansions, finished basements, and pool equipment already on the service all count.
If breakers trip on busy afternoons before you add a second charger, mention it. Charging load stacks with summer AC and cooking. Our panel capacity guide explains that overlap.
Smart load management options
Some installations use load-sharing equipment that reduces charge rate when the house is near capacity. Others schedule charging so both cars never peak at once. The right approach depends on your panel, your driving pattern, and the hardware you choose.
Bring vehicle manuals and charger spec sheets to your estimate request. Conflicting paperwork is common—we reconcile it on site.
Two locations: garage and carport
If one car parks outside, cable route length, weather-rated hardware, and disconnect placement affect scope the same way as a single outdoor install. Photos of both parking spots and the panel path help.

Permits and inspections
Municipalities in Cobb, Paulding, Cherokee, and surrounding counties handle permits differently. We coordinate what your address requires so you are not interpreting checklists alone.
