Buying Guide: Things To Consider When Select Automatic Transfer Switch

Automatic Transfer Switch

a) Size

The size of the automated transfer switch is the most important thing to keep in mind. The amperage the switch can safely handle or deliver is indicated by the switch’s size. The more amps a transfer switch can tolerate, the better it is at maximizing power.

In addition, the sizes might range from 30 to a million or more. PSI, for example, has automated transfer switches ranging from 200 to 5,000 amps. Your generator’s amperage requirements will increase with its size.

Here, you’ll learn how to properly and successfully use the switch. A 200-amp main breaker necessitates the use of an automated transfer switch. Before making a purchase, make sure the automatic transfer switch on the generator works properly.

This automated transfer switch from Reliance Controls Corporation is the finest option for you. As far as size goes, this Reliance transfer switch is ideal for areas that need to be covered.

b) Wattage

When it comes to measuring power, a watt is a universally applicable standard. In addition, an amp is a unit of measurement for electricity (which is the reason amps are used to decide the size of your transfer switch). So why are watts so important? Because you need to know how much power your building consumes.

Additionally, the amount of power needed to run selected emergency services (lighting, machinery, safety features, and so forth.). Choosing the right automated generator transfer switch is quite crucial. Your business’s size and kind of generator will determine the size and type of transfer switch needed for safe and efficient operation based on wattage.

If you want to get the most accurate results, we recommend working with a trained circuit tester! The Generac RXSW200A3 200 AMP Smart Switch was judged to be the greatest automated transfer switch. The finest generator transfer switch has 48000 watts of power capacity.

c) Cabinet Type

Make sure that the transfer switch body is adequately protected for the location where you intend to put it. NEMA criteria were created to assess this match. For indoor use, these devices provide anti-splash protection.

Aside from its limited waterproofness, the gear’s conformance with NEMA 2 shows that it is also suitable for interior use! The NEMA 3 rating indicates that the switch may be used outside. As a last bonus, it is shielded from the elements.

This type of switch is immune to icing damage. Choose the cabinet type of a transfer switch before making a purchase. For twin lighting, the Surge Guard 41260 Transfer Switch provides an adequate cabinet construction. It’s the perfect automated transfer switch for you at a price you can afford.

How Does It Work?

Before you buy a generator transfer switch, you need to know how it works. ATS switches, or automatic transfer switches, connect your backup generator to your house automatically. It’s common for electric power to travel from your local utility company to the main electrical board in your house, where it operates all of your circuitry.

The “brain” of your entire electrical system is an automatic transfer switch. They can automatically switch between utility power and generator power after they’re installed. In order to learn more about connecting a manual transfer switch, you may choose to consult further resources.

A power loss is detected by the transfer switch, and the generator electricity is automatically switched to your house. When the electricity is restored, it switches your house back to utility power and indicates when the power is returned. The MOES Dual Power Automatic Transfer Switch is a good choice if you’re looking to get a proper home run transfer switch.

Final Words

Having a generator isn’t enough on its own, though. An automated transfer switch is a vital aspect of your electrical circuit if you need constant power for your systems or want to enhance the safety of your house.

An automated transfer switch is essential for a safe and dependable electrical system. In the event of a power loss, you’ll be able to use your backup power source with minimal interruptions.
