A generator interlock kit (or a transfer switch), eliminates the need for extension cords to power appliances. [2]Like a transfer switch, an interlock kit lets the generator energize the panel and all of its circuits (up to the load capacity of the generator); not just corded appliances.
Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical ...
A standby generator is a back-up electrical system that operates automatically. [1] Within seconds of a utility outage an automatic transfer switch senses the power loss, commands the generator to start and then transfers the electrical load to the generator. The standby generator begins supplying power to the circuits. [2]
Large low-voltage molded-case and power circuit breakers may have electric motor operators so they can open and close under remote control. These may form part of an automatic transfer switch system for standby power. Low-voltage circuit breakers are also made for direct-current (DC) applications, such as for subway lines.
These switches allow the part of the system being worked on to be isolated while the rest of the system remains live. At high voltages, there are two switches of note: isolators and circuit breakers. Circuit breakers are load-breaking switches where as operating isolators under load would lead to unacceptable and dangerous arcing. In a typical ...
Switches: to control the flow of electricity, and isolate equipment. [28] The substation busbar: typically a set of three conductors, one for each phase of current. The substation is organized around the buses, and they are connected to incoming lines, transformers, protection equipment, switches, and the outgoing lines. [27] Lightning arresters
