When a storm hits Syracuse, no one wants to stumble in the dark looking for flashlights and extension cords. More homeowners across New York are installing backup power systems that start quickly and run safely when the grid fails.

The two main ways to connect a generator are a generator interlock or an automatic transfer switch, often called an ATS. Both keep power flowing safely, but they work differently.

Here’s what sets them apart and how to decide which one fits your home.

What Is a Generator Interlock

A generator interlock is a manual safety device that lets you connect a portable generator to your home’s electrical panel without risking backfeeding into the grid. It keeps utility power and generator power from running at the same time.

Interlocks are simple, affordable, and ideal for smaller homes or those that only lose power occasionally. When the power goes out, you connect the generator to a power inlet and slide the interlock plate to isolate the main breaker. Then you can choose which circuits to power, like lights, the refrigerator, or a sump pump.

For families in Rochester or anywhere else in our service area who want a cost-effective solution, a generator interlock works well. Home Power Systems installs code-compliant interlocks designed for New York’s conditions and power standards.

What Is an Automatic Transfer Switch

An automatic transfer switch, or ATS, is built for standby generators. It constantly monitors your utility power and automatically switches to generator power when it senses an outage. Once utility service is restored, it switches back again.

You don’t need to go outside or flip any switches. The ATS handles the transition within seconds.

In Syracuse or Buffalo, where winter storms can cause long outages, an automatic transfer switch keeps homes running smoothly. It powers essential systems like heat, refrigeration, and medical equipment without interruption.

Home Power Systems installs and services ATS systems throughout New York, ensuring safe and reliable operation during every outage.

Key Differences Between Interlock and ATS

Both options safely transfer power between the generator and the utility, but they differ in operation, cost, and capacity.

Operation

Interlocks are manual. You connect and activate your generator yourself.

Automatic transfer switches handle everything automatically when power is lost.

Cost and Complexity

Interlocks cost less and are easier to install.

ATS systems have a higher upfront cost but offer complete convenience and full-home coverage.

Power Capacity

Interlocks are best for smaller homes or powering selected circuits.

ATS systems can handle higher loads and provide whole-house power.

Safety and Maintenance

Both are safe when installed properly.

An ATS includes built-in monitoring and additional protection features that meet strict New York codes.

A smaller home in Rochester might use an interlock, while a larger home in Syracuse or Buffalo with more essential systems could benefit from an ATS.

When You Need Each in New York Homes

Choosing between a generator interlock and an automatic transfer switch depends on how often you lose power, what you need to power, and your budget.

An interlock is a good fit if:

• You have a portable generator.
• You only need to power a few circuits or smaller appliances.
• You don’t mind connecting the system manually.
• You want a lower-cost option.

An automatic transfer switch is better if:

• You own a standby generator that powers your entire home.
• You live in an area like Syracuse or Rochester where outages are frequent.
• You want your generator to turn on and off automatically.
• You rely on uninterrupted power for heating or medical devices.
