Description

Save space & money with our new combination manual transfer switch and generator tap box with Cam-Lok receptacles

This offering comes in two sizes: 400–800 amp and 1200–2400 amp NEMA 3R enclosures.

Our new combination manual transfer switch and generator tap box features Cam-Lok receptacles with an assortment of configurations available to meet any application. This combination product comes pre-wired from PSI, with the Cam-Lok connectors of a generator tap box already wired to the manual transfer switch component.

This helps cut down on additional wiring and save space in tight confines where it may come at a premium. It also helps minimize additional wiring for a simpler backup generator load transfer solution.

Both variants of the product include a lockable Cam-Lok section on your choice of the left- or right-hand side, a sub-panel, and a drip shield. Customers can also choose between 208–240 volt, 480 volt, and 575–600 voltage variants of the product as needed.

  • Cam-Lok section has lockable door
  • 60″ H x 42″ W x 20″ D with sub-panel
  • Wall-mount or free-standing if bottom tabs are removed
  • Non-fusible and fusible for 400, 600, 800 amp
  • Drip shield is also included

Cam-Lok connectors can be mounted on either side of the enclosure. Wiring from the Cam-Lok connectors to the transfer switch comes prewired by PSI. Perfect for when space is at a premium. This eliminates wiring between the manual transfer switch and the generator tap box.

They’re built to NEMA 3R enclosure ratings, with switch components labeled UL1008 through 1200 amps and IEC-rated 1600 through 3000 amps.

Product Usage

A manual transfer switch with an integrated generator tap box is useful in any number of load transfer applications. Most frequently used to easily transfer a building’s electrical supply from a standard electrical supply to a backup generator during outages and interruptions.

When combined with a generator, a manual transfer switch allows for a quick and painless transition to backup power as needed, without the need for specific wiring and backup power for each device or system.

This manual transfer switch is shipped pre-wired by PSI Power & Controls to minimize the need for additional wiring to a generator tap box, allowing you to save time and space in any configuration. The addition of convenient Cam-Lok receptacles under a locking door makes switching power sources easier and safer than ever.

Customers installing PSI’s combination manual transfer switch with Cam-Lok receptacles should familiarize themselves with all relevant specifications, standards, and diagrams before beginning. Make sure to follow the instructions for your specific unit based on amps, fusible or non-fusible, Cam-Lok mounting side, and three-pole or four-pole switch.
