What We Provide
Automatic Transfer Switch
Install an automatic transfer switch (ATS) that detects a power outage and switches your home or business to generator power within seconds — no manual action required.
Manual Transfer Switch
Install a manual transfer switch for portable generators, allowing safe connection without the risk of backfeeding the utility grid.
Standby Generator Hookup
Complete electrical connection for whole-home standby generators, including transfer switch, load center connections, and utility coordination.
Generator Sub-Panel
Install a dedicated generator sub-panel to power essential circuits — HVAC, refrigerator, lights, and outlets — during an outage.
Portable Generator Interlock
Install a panel interlock kit that allows safe use of a portable generator through your existing panel without a separate transfer switch.
Generator Maintenance Wiring
Inspect, repair, or upgrade existing generator wiring and transfer switches to ensure reliable operation when you need it most.
Our Process — What to Expect
Load Assessment & Generator Sizing
We assess your electrical load to determine the right generator size for your needs — whether you want to power essential circuits only or your entire home.
Transfer Switch Selection
We recommend the right transfer switch type (automatic vs. manual, whole-home vs. essential circuits) based on your generator, budget, and backup power goals.
Permit Application
Generator installations require an electrical permit in most Atlanta-area jurisdictions. We apply for and manage the permit on your behalf.
Electrical Installation
We install the transfer switch, run all required wiring, make connections at the panel, and prepare the generator connection point.
Gas Coordination (if needed)
For natural gas or propane standby generators, we coordinate with your gas utility or propane supplier for the fuel connection.
Testing & Inspection
We test the complete system — simulating an outage to verify automatic switchover — and coordinate the required electrical inspection.
Cost & Pricing Factors
Every job is different. Here are the key factors that affect the cost of this service in the Atlanta area:
Generator Size
Larger generators that power more circuits require larger transfer switches and more wiring, increasing installation cost.
Transfer Switch Type
Automatic transfer switches cost more than manual switches but provide hands-free operation during outages. Whole-home ATS units are more expensive than essential-circuit versions.
Distance from Panel
The distance from your electrical panel to the generator location affects the amount of wiring and conduit required.
Panel Capacity
If your panel is already near capacity, a sub-panel or panel upgrade may be needed to properly support the generator connection.

Frequently Asked Questions
What is a transfer switch and why do I need one?
A transfer switch safely connects a generator to your home's electrical system. Without one, connecting a generator directly to your panel can backfeed the utility grid — a serious hazard for utility workers and your equipment.
What is the difference between a standby and portable generator?
A standby generator is permanently installed, runs on natural gas or propane, and starts automatically during an outage. A portable generator runs on gasoline and must be manually started and connected.
How large a generator do I need for my Atlanta home?
It depends on what you want to power. A 7,500–12,000 watt generator can power essential circuits (HVAC, refrigerator, lights). A whole-home generator typically ranges from 20,000–22,000 watts for an average Atlanta home.
Do I need a permit for generator installation in Atlanta?
Yes. Generator installations require an electrical permit in Atlanta and most surrounding jurisdictions. We handle the permit application and inspection coordination.
Can you install a generator interlock on my existing panel?
Yes. A panel interlock is a cost-effective alternative to a full transfer switch for portable generator users. We install interlocks on most major panel brands.
How long does generator wiring installation take?
A transfer switch installation for a portable generator typically takes 2–4 hours. A full standby generator hookup with automatic transfer switch may take a full day or more depending on complexity.
