The Benefits of Using Automatic Transfer Switches

When the power goes out unexpectedly, every second counts. Whether you’re at home, managing a business, or operating a critical facility, restoring electricity quickly and safely is a top priority. That’s where an automatic transfer switch (ATS) becomes a game-changer.

An automatic transfer switch works alongside your generator to detect power loss and switch your electrical system from the mains to your backup generator—automatically. It does all of this within seconds, without any manual input. In this blog, we’ll explore the key benefits of using an ATS and why it’s a smart addition to any reliable backup power setup.

Seamless Power Transitions

One of the biggest advantages of using an automatic transfer switch is the instant switch to backup power. As soon as the ATS detects a power outage, it automatically starts the generator and transfers the load—usually within seconds. Once the main power returns, the ATS reverses the process.

This means:

• No scrambling in the dark to turn on the generator
• No interruption to essential appliances or business operations
• Peace of mind during storms or unexpected outages

For households with medical equipment, businesses with critical operations, or facilities like aged care homes and hospitals, that speed and smooth transition can be essential.

Enhanced Safety

Switching between power sources manually can be risky if not done correctly. An ATS eliminates the need for manual switching, reducing the risk of electrical shock, backfeeding, and equipment damage.

Backfeeding—when electricity flows back into the grid from your generator—can be dangerous for utility workers and damaging to the electrical grid. An ATS ensures the connection to the grid is safely cut off before the generator takes over.

Protects Your Equipment

Frequent power outages and voltage fluctuations can be harmful to your appliances, electronics, and machinery. An ATS helps protect your investment by:

• Delivering stable power during transitions
• Preventing power surges and electrical faults
• Keeping sensitive systems like computers and HVAC units running smoothly

If you rely on consistent power to protect data, maintain refrigeration, or run equipment, an ATS helps reduce downtime and avoid costly repairs.

Ideal for Unattended Operation

Whether you’re on holiday or running a remote site, you might not always be around when the power goes out. With an ATS, you don’t need to be on-site to activate your generator. It kicks in automatically and keeps your property powered—even when no one’s there to manage it.

This is especially helpful for:

• Remote work sites or farms
• Holiday homes or rentals
• Businesses operating outside regular hours

Convenient and Low-Maintenance

An automatic transfer switch takes the hassle out of power management. Once installed, it works in the background with minimal input from you. Most models also include user-friendly control panels and indicators that let you monitor performance at a glance.

Some modern ATS units even come with remote monitoring features, allowing you to check the status of your generator from your phone or computer.

Compatible with a Range of Generator Systems

ATS units are available in different sizes and configurations, meaning they can be matched to a wide range of generator systems—from small residential setups to large-scale industrial installations.

Common configurations include:

• Single-phase or three-phase models
• Open transition (break-before-make) for general use
• Closed transition (make-before-break) for critical power environments like hospitals or data centres
• Service entrance-rated ATS units that combine transfer switching with a main breaker for added convenience

This flexibility means there’s an ATS solution for almost any property or application.

Increases Property Value and Energy Resilience

Having a backup generator system with an automatic transfer switch is a valuable asset. Not only does it increase your property’s energy resilience, but it also makes your home or business more attractive to future buyers who value uninterrupted power access.

For businesses, an ATS also helps you stay compliant with operational and safety standards—especially in industries that require continuous power to meet regulatory obligations.
