The ASCO Transfer Switch makes backup power possible. A Transfer Switch enhances power availability by transferring electrical loads to alternate sources of power.

The ASCO Transfer Switch is available in three options:

• Manual transfer switch is the simplest type, manual transfer switches require a person to operate a mechanical switching mechanism.
• Non-automatic transfer switch is operator initiated, local or remote electrical controls to transfer loads on command.
• Automatic transfer switch requires no human interaction to switch loads to emergency power and back again whenever outages occur.

A Service Entrance Power Transfer Switch combines automatic power switching with the disconnecting, grounding, and bonding required for use as service entrance equipment.

Bypass-isolation allows the primary automatic transfer switch to be inspected, tested, and maintained without interrupting power to the load.
