Transfer Switch

Receiving and Storage

After receiving the transfer switch inspect the cabinet for any damage that may have occurred during shipping. If the transfer switch is not installed immediately, cover the cabinet and store in a dry area. Condensation can corrode the contacts and other metal parts.

Location

The transfer switch should be located as close as possible to the engine generator or to the alternate power source. If possible, there should be a clear line of sight between the transfer switch and the engine generator.

Line Connections

Refer to the drawings posted inside the cabinet door and in the drawing packet for customer connections.

Before drilling and punching holes in the cabinet for wiring connections cover the transfer switch with a protective covering. Small debris falling into the automatic transfer switch may jam the switching mechanism or may cause electrical failure.

Ensure that the normal (primary), emergency (alternate), and load isolation switches are open before making connections. Connect the load, normal source, and emergency source power cables in the same phase sequence. Refer to the latest NFPA 70 and Field Connections Wiring Diagram for cable sizes and torque requirements.

All other standard customer connections are made to PTB1 on the left side of the mounting panel. Use approved 14-gauge wire for all control connections. Typical field connections are shown below.
