FAQs

Questions & Answers for NDQ2A Series

  • What are the two types of automatic transfer switches?
    There are two basic types of automatic transfer switches, circuit breaker and contactor. The circuit breaker type has two interlocked circuit breakers, so only one breaker can be closed at any anytime. The contactor type is a simpler design that is electrically operated and mechanically held.
  • How do automatic transfer switches work?
    How Does an Automatic Transfer Switch Work? An automatic transfer switch, or ATS switch, connects your standby generator to your home. ... When the transfer switch detects a power outage, it switches your home to generator power. Afterward, it detects when the power is restored and switches your home back to utility power.
  • What is Auto Transfer Switch?
    A transfer switch is an electrical switch that switches a load between two sources. ... An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
  • Do I need a permit to install a generator transfer switch?
    Technically yes, you need a permit from the local authorities whenever you install any permanent additions to your house. Generator transfer switches are no exception. However, if you hire a certified electrician for the installation, they will usually be able to sort out the permits on your behalf.
  • Which is better transfer switch or interlock?
    Interlock switches are usually less sophisticated and therefore less expensive than automatic transfer switches. They require training and an understanding of the building's electrical system for safe use.
  • Can you run a generator without a transfer switch?
    It's not only less safe to run a generator without a transfer switch, but you'll limit the devices that your generator can power,” says Dave Trezza, who oversees generator testing for Consumer Reports.
