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

Image
        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.

Backup Power in our Houses

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:-

Guidelines for Automatic Transfer Switch Selection

Choosing the right transfer solution for power applications requires information about the technology and the applications.

Once upon a time, I worked for a power systems integrator. Our company engineered, manufactured, assembled, and tested emergency power systems for data centers around the globe. 

Static Power Transfer Switches (STS)

IN ANY ELECTRICAL SYSTEM, a transfer switch functions to remove electrical load from one source of supply-usually because of a power failure-- and transfer that load to an alternate source. In some systems, that's done manually. Most often, however, the switch operates automatically. The technology is not new (EA June 1997).

What To Know About Transfer Switches

What To Know About Transfer Switches? A generator transfer switch is necessary to isolate the generator from the utility system when you install a back-up generator to your home’s wiring system. Failure to properly transfer your power places you, your family and utility workers at great risk of electrocution.

How to Install a Power Transfer Switch

How to Install a Power Transfer Switch? A generator transfer switch (TS) allows normal alternating circuit (AC) line voltage to connect with the utility power, but when there is an AC problem, the switch diverts the electric load to a generator. The law states that you must install a power transfer switch before you connect a generator to a building's electrical wiring system.

Transfer Switch Wiring: How to Wire a Transfer Switch Transfer switches are basically used for switching power from a primary power source to a secondary or tertiary power source. They are useful for emergency power generators, in order to back up power from the utility source. A transfer switch may be a manual switch, automatic switch, or a combination of both. It becomes necessary to transfer power from a primary source to secondary source in case the incoming power quality deviates from set limits. A transfer switch is made up of an actuator and a toggle mechanism. An actuator can be activated either manually or automatically, in order to supply energy to the movable contacts on the toggle mechanism. Transfer switches prevent the damage of utility equipments by allowing for operation of the generator without back-feeding to the utility.

Transfer Switches  If you are thinking about purchasing a generator to provide emergency power to your home or business, you will need a generator transfer switch to safely supply the necessary power. Call me to have a transfer switch installed with your new generator.

What An Automatic Transfer Switch Does?

Do You Know What An Automatic Transfer Switch Does? An Automatic Transfer Switch is an automatic transfer of power source from one to another, this type of switches is more convenient compare to the manual type. An electrical transfer switch is very useful nowadays, because when the main power source is disconnected, it will automatically transfer the power to another electric system.
