Automatic Transfer Switches

The safe, high-speed solution for generator power transfer and load management.

Automatic transfer switches (ATS) instantly transfer power from utility electrical sources to generator power to achieve uninterrupted power generation. Whether powering a large-scale industrial factory or a residential refrigerator, automatic transfer switches provide 24/7 electrical protection to prevent data/communication loss or equipment failure.

As Virginia’s leading electrical service provider, we can guide you through best practices for managing multiple electrical sources, including:

  • Right-sizing automatic generator switches and related equipment
  • Managing overload protection
  • Training you for emergency and day-to-day operations
  • Selecting the optimal fuel source for your area or application
  • Testing and exercising generator switches to ensure proper sequence of operations
  • Systems available in multiple enclosures based on application, including NEMA 1, NEMA 3R and NEMA 12 enclosures

Automatic Transfer Switch Installation

Depending on the code and utility requirements, space limitations and location preference, the ATS can be the most important cost consideration of a generator installation. Some automatic transfer switches are UL listed and rated for Service Entrance installations, while others are not.

Optional auxiliary contacts, strip heaters, alarm monitoring, remote monitoring and preventative maintenance testing should be considered when selecting your new ATS. Our factory-certified technicians provide turnkey generator transfer switch installation and servicing, regardless of scale or OEM.

Troubleshooting, Maintenance and Repair

Harris Power ensures that your transfer system is fully optimized for the latest in Power Generation safety regulations and standards. Our technicians provide expert internal and external inspection and repair of transfer switches and related components.

Testing for proper transfer of generator power back to utility power is vital on a monthly or quarterly basis. ATS are generally mechanical in nature; if not tested properly, there is a potential for fuses, relays, contacts and other electrical components to critically fail in emergency situations.
