an electrical device for switching loads between alternate power sources
a relatively inexpensive device that will prevent an improper connection during an outage
A device used to alternate between the reception of over-the-air radio frequency signals via connection to an antenna and the reception of radio frequency signals received by any other method, such as from a TV interface device. FCC: 47 CFR 15.115.
An electronic device that under certain conditions will disconnect from one power source and connect to another power source.
A device which cuts your home off from utility provided power when you turn your generator on. This prevents your generator from backfeeding onto the utility lines and causing possible electrocution of utility workers.
A device that will switch a load from the main utility power source to a standby power source.
A switch designed to transfer electricity being supplied to loads (appliances, etc.) from one source of power to another. (A transfer switch may be used to designate whether power to a distribution panel will come from a generator or inverter.)
A switching device to select either normal utility power, or emergency generator power, and connect this power to the electric load. There is an automatic transfer switch (no operator required) and a manual transfer switch (an operator must be present for stop-start operation), and it's sole purpose is to insure that these two different voltage systems can not unite. Article 702.6 National Electric Code, NEC dates 2002 states the following: "A transfer switch is required for all fixed or portable optional standby power systems."
A device for transferring one or more loads from one power source to another.
A switch that will transfer current from one circuit path to another without interrupting the flow of the current.
A switch designed to automatically connect to a generator when the primary power fails.
Transfer switches allow switching from a primary power source to a secondary or tertiary power source and are employed in some electrical power distribution systems. Most often transfer switches can be seen where emergency power generators are used to back up power from the utility source. The transfer switch allows switching from utility power to emergency generator power.
