Manual Transfer Switches

What Is a Manual Transfer Switch?

For business owners, nothing is more frustrating than losing power in your store, office, or commercial property. Whether you own a small sporting goods store or an HVAC company, constant, reliable electrical power is crucial when operating your business.

Without it, many critical duties and responsibilities are delayed or lost entirely—your heating and cooling system, electrical system, security systems, computer networks (including individual workstations, servers, printers, etc.) and your building’s tankless water heater are just some of the vital systems relying on electrical power in your business.

A manual transfer switch is an easy solution to keep the lights and other important systems powered during a temporary or emergency power outage, allowing you to keep your business up and running with minor productivity loss.

How to Pick the Perfect Manual Transfer Switch

Your manual transfer switch helps ensure the delivery of fast, safe electrical current. To select the proper manual transfer switch, first calculate the wattage you require to operate your generator. Next, select a switch that is rated to the generator’s largest outlet. This will be anywhere from 30 to 3000 amps. You should also verify that the switch can handle the amount of dedicated circuitry required. You will also want to select a manual transfer switch that features a built-in wattage meter. This will help prevent overloading the system and causing damage to the generator or your appliances.

How Does a Transfer Switch Work?

Transfer switches are an effective means of ensuring your business has uninterrupted access to electrical power in the face of outages and incidents. They provide a no-mess and no-stress function, granting you fast and safe access to power from your generator when you need it most. But to find out exactly how a transfer switch operates, you might need a bit of an explanation.

As a leader in superior electrical products, PSI Control Solutions is wholly dedicated to ensuring your business receives only the absolute best to meet your needs. We strive to bring you custom power solutions to ensure your business is never left in the dark.

Why Do I Need a Transfer Switch?

A transfer switch is not required to operate your generator. Extension cords can be used to bring power directly from your generator in times of need without the use of a switch. However, this method is severely limited. When you do not use a transfer switch, you are limited by:

  • Not using a switch is far slower and requires considerably more effort
  • Not using a switch is considerably less safe
  • Plugging methods limit your access to power, meaning major operations must halt
  • Returning to utility power after an outage is far more involved without a transfer switch

Transfer switches are devices that are essential for emergency power electrical installations when generators are used. Whether your application is industrial or commercial in nature, power supply continuity and electrical distribution are critical.

A manual transfer switch allows you to start a generator and restore power to predetermined circuits when utility power fails. This is a reliable, simple, and cost-effective method to provide building owners with a high level of safety and security.
