Serving Our Neighbors Since 1970
A transfer switch is the critical link between your whole home generator and your Campbellsville, Kentucky home's electrical system - and getting it installed correctly is not optional. A-1 Cooling, Inc. has been providing expert electrical work throughout Taylor County and the surrounding Kentucky communities since 1970, and our licensed electricians install both automatic and manual transfer switches that meet current electrical codes and keep your family safe during every power outage. Whether you're adding a generator to your property for the first time or upgrading an existing setup, we handle the entire process from evaluation to final inspection. Contact us today to schedule your transfer switch consultation.
What a Transfer Switch Does
A transfer switch is a specialized electrical device that sits between your utility power feed and your generator. Its job is straightforward but essential: it prevents your generator and the utility grid from feeding power into your home at the same time. Without a transfer switch, you risk backfeeding - a dangerous condition where generator power flows backward through your electrical panel and into the utility lines outside your home.
Backfeeding doesn't just damage your equipment. It sends live electricity back into power lines that utility workers may be repairing during the outage, creating a lethal electrocution hazard for the linemen working to restore your power. It's illegal in Kentucky and throughout the United States, and for good reason. Every jurisdiction in Taylor County requires a properly installed transfer switch whenever a generator is connected to a home's electrical system.
At A-1 Cooling, Inc., we've been installing transfer switches for over five decades, and we've seen the consequences when homeowners try to skip this step or hire someone without the proper training to install one. Improperly wired transfer switches can fail silently, leaving your family exposed to the very risks they're supposed to prevent. Our electricians do it right the first time - every connection verified, every circuit tested, every installation inspected.
Making the Right Choice
Choosing between an automatic transfer switch (ATS) and a manual transfer switch (MTS) depends on your generator type, your budget, and how much involvement you want during a power outage. Our electricians walk every Campbellsville homeowner through both options during the consultation so you can make an informed decision.
An automatic transfer switch monitors your utility power continuously. The moment it detects an outage, it signals your standby generator to start and then transfers your home's electrical load from the utility feed to the generator - all without you doing anything. When utility power is restored, the ATS reverses the process, transferring your home back to grid power and signaling the generator to shut down.
Best for:
An ATS is what we install alongside every whole home generator project. The switch and generator communicate directly, creating a seamless backup power system that activates in seconds.
A manual transfer switch requires you to physically switch your home's electrical load from utility power to generator power using a handle or series of breakers on the switch panel. You also need to start your generator manually and run a power cord from the generator to the transfer switch inlet box mounted on the exterior of your home.
Best for:
A manual transfer switch is a significant safety upgrade over extension cords or improvised connections. It gives you a dedicated, weatherproof inlet on the side of your house and a switch panel near your electrical panel that lets you select which circuits receive generator power.
Here's a practical way to think about it: if you're investing in a permanently installed standby generator, an automatic transfer switch is the clear choice - it's specifically designed for that application, and skipping the ATS would undermine the whole point of having a standby system. If you're working with a portable generator and want a safer way to use it, a manual transfer switch gives you that safety at a fraction of the cost.
Our team at A-1 Cooling, Inc. doesn't push homeowners toward the more expensive option. We assess your situation, your generator setup, and your goals, and we recommend the switch that actually makes sense for your Campbellsville home. Reach out to our team and we'll help you determine the right fit.
Our Process
Every transfer switch installation we perform in Campbellsville and the surrounding communities follows a structured process developed over 55 years of electrical work. Here's what to expect when you hire A-1 Cooling, Inc. for your transfer switch project.
Before we install anything, we need to understand your home's electrical demands. Our electricians evaluate your existing electrical panel, identify which circuits are critical during an outage, and calculate the total load to determine the proper transfer switch size. An undersized switch will limit what your generator can power. An oversized switch wastes money. We get the sizing right.
Based on the load assessment, we select a transfer switch rated for your specific generator and electrical system. For automatic transfer switches paired with standby generators, we match the switch to the generator's output capacity and your panel's amperage rating. For manual transfer switches, we select a unit with enough circuit positions to cover your essential loads - typically heating and cooling equipment, refrigeration, lighting, well pumps, and medical devices. If a heat pump is on that list, our guide to sizing a standby generator for a heat pump and well pump explains the loads the switch and generator have to carry.
Our licensed electricians handle the complete installation, which includes mounting the transfer switch adjacent to your main electrical panel, running conduit and wiring between the transfer switch and your panel, connecting critical circuits from your main panel through the transfer switch, installing the exterior power inlet (for manual transfer switches with portable generators), connecting generator communication wiring (for automatic transfer switches with standby generators), and verifying all connections for proper torque, grounding, and polarity. Every wire is labeled. Every connection is verified. Every ground is tested.
Once the installation is complete, we test the entire system under real operating conditions. For automatic transfer switches, we simulate a utility outage and verify that the generator starts, the switch transfers power, and all critical circuits receive electricity. We then restore simulated utility power and confirm the switch transfers back and the generator shuts down properly. For manual transfer switches, we walk you through the complete operation - how to start your generator, connect it to the inlet, and switch each circuit over.
All transfer switch installations in Taylor County require electrical permits and inspections. A-1 Cooling, Inc. handles the permitting process and coordinates the inspection with local authorities. We don't ask you to pull your own permits or chase down inspectors - that's our responsibility, and we take care of it.

Contact usHVAC Protection
Your heating and cooling system represents one of the largest investments in your Campbellsville home, and a properly installed transfer switch plays a direct role in protecting that investment during power outages.
When utility power is restored after an outage, it often comes back with voltage surges and fluctuations that can damage sensitive electronic components in modern HVAC equipment. Your Bryant air conditioning system, heat pump, or furnace relies on circuit boards, variable-speed motors, and electronic controls that are vulnerable to these surges.
A transfer switch provides a clean, controlled transition between generator power and utility power, eliminating the surge that occurs when grid electricity suddenly floods back into your panel.
Safety First
Transfer switch installation is not a DIY project. It involves working inside your main electrical panel with live circuits, and mistakes can result in electrocution, house fires, or dangerous backfeed conditions. Kentucky electrical codes require that this work be performed by a licensed electrician, and local inspectors in Taylor County verify that installations meet all applicable safety standards.
We still encounter homeowners in the Campbellsville area who have connected generators to their homes without a transfer switch. Some have used "suicide cords" - male-to-male extension cords that plug into both a generator and a wall outlet - to energize circuits during an outage. This practice is illegal in every Kentucky jurisdiction, extremely dangerous to utility workers repairing downed lines, potentially fatal to anyone who contacts the energized wiring, and capable of destroying your generator and household appliances when utility power returns.
