Everything You Should Know About Using an Automatic Transfer Switch with Home Backup Generators

Southampton, United States - December 4, 2025 / Long Island Power Systems LLC /

Southampton, NY Long Island Power Systems provides dependable backup power generator solutions for Long Island homeowners. Installing home backup generators with an Automatic Transfer Switch (ATS) helps maintain electricity during outages. The ATS manages power flow automatically, helping to keep lights, heating, and essential appliances running smoothly and safely during storms, seasonal outages, or unexpected power interruptions.

What Is an Automatic Transfer Switch (ATS)?

An Automatic Transfer Switch (ATS) connects a building’s electrical system to a backup residential generator and automatically manages the switch between utility and generator power. When an outage occurs, the ATS detects the loss of electricity, starts the generator, and transfers the power source seamlessly. This process keeps essential systems like lighting, refrigeration, and heating running without interruption.

The ATS continuously monitors the power supply and restores normal operation once electricity returns. It then shifts the load back to the utility and powers down the generator. This automation removes the need for manual intervention, providing a reliable, safe, and efficient way to maintain continuous power for homes, offices, and light commercial facilities during unexpected outages.

Benefits of Installing an ATS

Seamless Power Transfer

An ATS maintains an uninterrupted power flow by switching from the main grid to generator power instantly. This fast transition keeps essential systems like heating, cooling, and appliances operational without downtime, keeping the home safe and comfortable.

Safety Advantages

One of the most important benefits of an ATS is electrical safety. It prevents backfeeding, a dangerous condition that can occur when power flows back into utility lines. This protection safeguards both your household and local utility workers.

Convenience for Homeowners

Homeowners using an ATS no longer need to go outside or manually start their generator during a storm. Once installed, it automatically provides electricity to vital appliances and systems such as sump pumps, refrigerators, and security devices. This convenience allows families to stay comfortable and focused on safety during outages.

Situations Where an ATS Is Recommended

Areas with Frequent Power Outages

Homes located in regions with repeated storms or unreliable grid power benefit the most from an ATS. On Long Island, where severe weather often causes service interruptions, residents can rely on a backup generator to maintain continuous power.

Homes with Critical Medical or IT Equipment

For households that rely on medical devices or computer systems, even a short power loss can create serious inconvenience or risk. An ATS helps maintain continuous operation, providing stable electricity for oxygen machines, medical refrigerators, or home servers.

Larger Residential Properties

Homes with greater electrical loads often have multiple appliances running at once. In these properties, an ATS helps manage power flow efficiently between the utility and the generator, keeping all systems balanced and functioning properly.

ATS vs Manual Transfer Methods

Manual Generator Start

Manual transfer systems require homeowners to start their generators and switch circuits by hand. This method takes time and can be difficult during bad weather or at night. It may also increase the chance of electrical hazards, including incorrect wiring or backfeeding.

Automatic Transfer Switch Advantages

An Automatic Transfer Switch activates automatically during an outage, transferring power to the generator in seconds. It operates without user intervention and maintains a stable, safe connection.
