Choosing the Right Automatic Transfer Switch

31st May 2022

When selecting an automatic transfer switch, it’s important to know what features to look for. Automatic transfer switches should have several types of protections, including fire, short circuit, overload, and low voltage. 

Finding a suitable switch for your needs can be a complicated task, but it’s not impossible. By using manuals and checking recommendations, you’ll be able to make an informed decision. In addition to safety features, you’ll want to consider your budget and how much power you need to transfer to another location.

Before buying an automatic transfer switch, consider the electrical system that it’ll protect. While these products are commonly sized for one or two circuits, you’ll want to make sure to select a model that is suitable for your needs.

What Is An Automatic Transfer Switch?

If you’re interested in having a reliable electrical system, an Automatic Transfer Switch will make the process a breeze. Automatic transfer switches operate automatically and monitor electrical parameters to switch the load circuit to an alternate power source in the event of a power failure.

By default, automatic transfer switches connect to the primary power source but will connect to an alternate supply only if it’s necessary or requested by the end-user. Typically, automatic transfer switches are more expensive than other switches but are known for being reliable and high-quality.

When installing an ATS, it’s important to follow the instructions that came with the switch. If you don’t understand the directions, contact a licensed electrician. If you don’t have the knowledge to install an ATS, you may cause damage to your home or circuit. To properly install an ATS, start by determining where to mount the transfer switch. 

Choosing the Right Automatic Transfer Switch

Here are some things you need to consider in order to choose the right automatic transfer switch. 

  • Amperage

Amperage or the current of an electrical circuit is a key indicator to determine the appropriate automatic transfer switch. If you frequently face power outages, you may already have an inverter or a generator installed in your home. But if you’re looking for a more reliable backup that can be ready to run as soon as there’s a power failure, an automatic transfer switch with a higher amperage rating is the way to go. Before choosing an Automatic Transfer Switch for your home, make sure you know how much amperage and voltage your circuits can handle. Amperage is a measurement of electrical current, and every circuit is rated for a certain amount of amperage. When circuits exceed their rated amperage, they will trip a circuit breaker. 

  • Ratings

The ratings of an Automatic Transfer Switch will tell you if the unit is suitable for heavy-duty usage. A higher current rating means that the automatic transfer switch can handle a heavier load. The best way to check the current rating is by comparing the switch’s specs with those of your home. You can also consider its price and warranty. Usually, the higher the current rating, the more expensive the automatic transfer switch will be.

  • Voltage

The Automatic Transfer Switch voltage should be appropriate for your application. Various commercial and industrial buildings operate at different voltages. It is essential to choose a switch that supports the voltage of your equipment and circuits. If you aren’t sure what voltage is required, you can always check with the manufacturer. A standard transfer voltage should be 50Hz or 60Hz, and an AC 400-volt switch should support both.
