Generator Transfer Switch Installation in McKinney, TX
Stop running dangerous extension cords through your windows. Top Flow Plumbing Co. installs professional generator-transfer-switch systems that allow you to power your entire home—including hardwired appliances like furnaces—safely and legally from a single plug.
Why You Need A Transfer Switch
Extension Cord Chaos
Running cords through open windows lets in cold air, rain, and exhaust fumes. It’s messy, tripping-prone, and inefficient
Hardwired Appliances
You cannot plug your furnace, water heater, or well pump into an extension cord. A generator-transfer-switch is the only way to power these essentials.
The Backfeed Danger
Plugging a generator directly into a dryer outlet ("suicide cord") is illegal and deadly. It sends electricity back to the grid, which can electrocute utility workers.
The Bridge Between Your Generator and Your Home
Whether you have a portable gasoline generator or a whole-home standby unit, the transfer switch is the brain of the operation. It physically isolates your home from the utility grid, ensuring safe power delivery. We install both Manual Transfer Switches (for portable units) and Automatic Transfer Switches (for standby units). If you are unsure which type fits your generator, get started with a quick consultation and we will size it perfectly.
Interlock Kits
A cost-effective solution for portable generators.

Protects Your Generator
A proper generator-transfer-switch allows you to balance the load, preventing your generator from stalling or overheating.
Don't Risk The "Suicide Cord"
Every year, homeowners damage their electrical panels or start fires by trying to "backfeed" their homes using homemade male-to-male cords. This is incredibly dangerous.

FAQ About Generator Transfer Switches
Got questions? We’ve answered the most common ones below to help you stay informed and confident in your next repair or replacement.
Yes. Any modification to your main electrical panel requires a permit and inspection, which we handle entirely for you.
A Manual Transfer Switch requires you to physically flip a lever to switch power sources (common for portable generators). An Automatic Transfer Switch does it instantly on its own (for standby generators).
It is highly discouraged. Installation involves working with live service entrance cables and major amperage. One mistake can be fatal.
Price depends on the amperage (30A vs 50A) and the number of circuits. We offer competitive, flat-rate pricing. You can contact us for a specific quote based on your generator size.
