Garage Subpanels & Dedicated Circuits in Newnan, GA
If your garage, workshop or detached building needs more power, a subpanel and dedicated circuits are usually the answer. Shocking Electric Solutions, Inc. installs garage and shop subpanels and dedicated circuits for homeowners in Newnan and Coweta County, sized for what you actually plan to run and wired to pass inspection.
What a Subpanel Is
A subpanel is a smaller breaker panel fed from your main panel by one large circuit. It gives you extra breaker spaces right where you need them, so you are not running long circuits back to the house for every tool or appliance. It does not add capacity to your electrical service. That is set by your main service, so we always check the load before adding one.
When a Subpanel Makes Sense
- Your main panel is full and has no open breaker spaces
- You want several 240-volt and 120-volt circuits in a garage or workshop
- You are powering a detached garage, barn, shed or workshop
- You are finishing a basement or building an addition and want circuits close by
- You are planning an EV charger, welder, air compressor or table saw along with other shop loads
Dedicated Circuits We Install
A dedicated circuit serves one appliance or tool, so it does not share the circuit with lights and outlets and is far less likely to trip. Common dedicated circuits we install include:
- Garage refrigerators and chest freezers
- Air compressors, table saws and other shop tools
- 240-volt welder receptacles
- Window or mini-split air conditioners
- Washers, dryers and kitchen appliances in remodels
- Sump pumps and well pumps
- Home office and server equipment
- EV chargers, see EV charger installation in Newnan
Load Calculation First
Before we add a subpanel, we do a load calculation on your home. It compares the service size with your existing loads and what you want to add. If there is enough capacity, we size the subpanel feeder and breaker to match. If not, we explain your options, such as load management or a service upgrade. This step keeps the main breaker from tripping and keeps wiring from overheating.
Detached Garages and Shops
Feeding a detached building has extra rules. The feeder usually runs underground in conduit at the depth the code requires. A subpanel in a separate building needs its own grounding electrode, with the neutral and ground kept separate, and a disconnecting means at the building. We plan the trench route with you, avoid utilities, and wire the building with the outlets and lighting you need, including GFCI protection where the code calls for it.
Garage Circuits and GFCI Protection
Garage outlets need GFCI protection. Older garages often have a single shared circuit for everything, which leads to nuisance trips when a freezer and a power tool share the same GFCI. Separating loads onto their own circuits fixes this. If your garage GFCI trips often, see why a GFCI keeps tripping.
Is My Main Panel the Problem?
Sometimes a subpanel is not the best fix. If your main panel is old, damaged, a brand with known problems, or simply too small, replacing it may make more sense. We will tell you plainly.

Frequently Asked Questions
Does a subpanel give me more power?
No. A subpanel adds breaker spaces, not service capacity. A load calculation tells us whether your current service can support the new loads.
Do I need a permit for a garage subpanel?
Yes. A subpanel and new circuits need an electrical permit and inspection through the City of Newnan or Coweta County. We pull it.
Can you run power to my detached shop or barn?
Yes. We run an underground feeder in conduit, install a subpanel with its own grounding, and wire the lights and outlets inside.
Why does my garage freezer keep tripping the GFCI?
Older freezers can leak small amounts of current, and sharing a GFCI with other loads makes trips more likely. We check the freezer and the circuit and set up protection that meets code.
Are estimates free?
Yes. Call (678) 552-9399 or text (470) 516-7261 to set up a free estimate.
