Change Over Switch For Generator Wiring Diagram

A changeover switch is a device that is used to connect two or more electrical circuits together. It is typically used to switch between a primary and a backup power source, such as a generator and the utility grid. Changeover switches are typically installed in commercial and industrial settings, where it is important to have a reliable source of power in the event of a power outage.

Changeover switches are available in a variety of sizes and configurations. The most common type of changeover switch is a manual switch, which is operated by a lever or switch. Manual changeover switches are typically used in applications where the power source is not likely to change frequently.

Another type of changeover switch is a motorized changeover switch. Motorized changeover switches are typically used in applications where the power source is likely to change frequently, such as in a data center or a hospital. Motorized changeover switches are typically controlled by a programmable logic controller (PLC).

Changeover switches are an important part of any electrical system that requires a reliable source of power. By providing a way to connect two or more electrical circuits together, changeover switches can help to ensure that critical systems are always up and running.

Here is a diagram of a typical changeover switch wiring diagram:

Changeover switch wiring diagram

In this diagram, the two power sources are labeled "Generator" and "Utility." The changeover switch is labeled "COS." The load is labeled "Load."

The circuit is wired so that the load is always connected to one of the power sources. When the COS is in the "Generator" position, the load is connected to the generator. When the COS is in the "Utility" position, the load is connected to the utility grid.

The COS is typically controlled by a switch or a PLC. When the switch is turned on, the COS moves to the "Generator" position. When the switch is turned off, the COS moves to the "Utility" position.

Changeover switches are an important part of any electrical system that requires a reliable source of power. By providing a way to connect two or more electrical circuits together, changeover switches can help to ensure that critical systems are always up and running.
