Automatic transfer switches meet all the standards!!!

ASCO's new 7000 Series Transfer Switches   Designed for emergency and standby operations, the 7000 Series units are purpose built - and approved - Automatic Transfer Switches rather than assemblies of contactors or circuit breakers.  This provides safeguards to consulting engineers and contractors who specify and install ATS systems.

     If you are installing a standby generator in order to have some electrical power to your home in the event of a utility power outage, it is important that you understand how to properly install a transfer switch.

Backup Power and Transfer Switches

        The basic standby or backup power system consists of an alternate power source and an isolation device capable of switching between the two power sources to provide the required power to the designated loads. The key in determining these requirements is based on the essential loads.

The Start                      Jasper H. and Phyllis Wyman have lost power dozens of times during the 31 years they've lived in their restored farmhouse in Pittsfield, Maine. But after the ice storm of 1998, which left the Wymans without electricity for more than four days, they decided they'd had enough of living by the light of kerosene lanterns, huddled around a wood stove, with no running water because the well pump was dead. (They saved the food from their refrigerator by burying it in a snowbank.) So Jasper plunked down $7,000 for a standby generator. Sitting in the garage, its exhaust vented via a pipe through the wall, this diesel-fueled mini power plant produces enough electricity to run their lights, refrigerator, well pump, furnace, and water heater—pretty much everything the Wymans need to weather a power outage. "If we get another storm like that, it's more than adequate to do everything we need it to do," Jasper says.  The Wymans join a growin

4 Types of Generator Transfer Switches

         Generator transfer switches are essentially an electrical power transfer device. This means that when the local or conventional source of power supply isn't available, they switch-on the power supply from the generator. The transfer switch should be of premium quality since it should be able to keep the two sources of electricity isolated. During phases of repeated power outages, the swapping between the primary power supply and generator-powered electricity can recur at short intervals. The generator transfer switch should be able to handle such demanding situations. Thus, it is vital that homeowners planning to install generator transfer switches know about the various options available in this niche. Types of Generator Transfer Switches Include:-
