Why Choose a Standby Generator Over Portable?
When the power goes out, you need reliable backup that works automatically. Here's why standby generators are the smart choice for Cumming homeowners.

| Startup | Automatic (10-30 seconds) | Manual setup required |
| Fuel Source | Natural gas/Propane (no refueling) | Gasoline (constant refueling) |
| Coverage | Whole home power | Limited outlets only |
| Weather Protection | All-weather enclosure | Must be covered/ventilated |
| Noise Level | Quiet operation (58-65 dB) | Very loud (70-80+ dB) |

Automatic Transfer Switches: The Brain of Your System
Your generator is only as good as the transfer switch that controls it. Here's what this critical component does and why professional installation matters.
How Your Transfer Switch Works
Monitors Utility Power
Continuously watches your electrical service for voltage drops or complete outages.
Starts Generator Automatically
Sends start signal to generator within seconds of detecting power loss.
Transfers Power Safely
Switches your home from utility to generator power in 10-30 seconds.
Returns to Normal
When utility power returns, switches back and shuts down generator automatically.
Transfer Switch Options
Whole-Home Transfer Switch
Powers your entire electrical panel. Best for properly-sized generators that can handle your home's full electrical load.
Recommended for: 22kW+ generators
Load-Shedding Transfer Switch
Automatically manages circuits to stay within generator capacity. Prioritizes essential loads like HVAC and refrigeration.
Recommended for: Smaller generators, larger homes
Why Professional Installation is Critical
Improper transfer switch installation is a fire hazard and code violation. Our licensed electricians properly size, wire, and test every installation to protect your family and property.

Generator Installation FAQs
How long does a generator install take?
Typically 1-2 days after permits are approved. The permit process usually takes 5-10 business days. We'll give you an exact timeline during your site assessment.
Do I need a permit for generator installation?
Yes, standby generators require electrical permits and sometimes gas permits. AG Electric pulls all required permits to keep your installation legal and protect your insurance coverage.
Natural gas vs propane — which is better?
Natural gas is more convenient (never runs out) but propane provides slightly more power per BTU. We'll assess your existing gas service and recommend the best option for your home.
How loud is a standby generator?
Modern standby generators operate at 58-65 decibels — about as loud as normal conversation. They're much quieter than portable generators and meet neighborhood noise ordinances.
Does it turn on automatically during outages?
Yes, that's the main benefit of standby generators. The automatic transfer switch detects power loss and starts your generator within 10-30 seconds. No manual intervention needed.
How often should I service my generator?
Annual service is recommended, plus any issues you notice during the weekly self-test. Generators that aren't maintained can fail when you need them most.
