Generator tap box wall mounts offer businesses a means of safely and effectively creating permanent connections to auxiliary and secondary power sources such as portable generator systems. This tap box product is wall-mounted and capable of weathering standard conditions both indoors and outdoors via protection offered by NEMA 3r and NEMA 3r 316 stainless steel rated enclosure options.

Our team can fabricate both 3 and 4 wire boxes. The amp range is available from 400-3200 amps as needed by your business, voltage ratings range 208-240, 480, and 575-600. Connections are securely made via standard male or female Cam-Lok® cables—both genders are available as per your specific needs.

This wall-mounted product is suitable for businesses that require a means of secondary power when a permanent generator is unnecessary or impractical. We often recommend our generator tap box wall mount to gas stations, banks, small businesses, office buildings, hospitals, stadiums, universities, and similar businesses.

Tap boxes are an ideal and cost efficient means of gaining access to portable or auxiliary generator power in the event of an outage or interruption (maintenance, utility power loss, emergency). Tap boxes are mounted and wired preemptively, connected directly to circuits you wish to remain active at all times such as lights, PA systems, HVAC, safety equipment, supply storage, or other applications.

In the event of an outage, Cam-Lok® cables can be routed to either predetermined circuits or can be applied to circuits as needed, providing safe and swift access to a stable power source for as long as may be necessary. Cam-Lok® cables are color-coded, helping you assess what goes where and assisting in avoiding any confusion or crossing in a time of duress.

PSI Control Solutions-supplied and or -fabricated equipment makes setup and installation simple and easy—however, purchasers should take note that correct amperage and voltage ratings are absolutely necessary and accessories should be chosen to suit your specific needs. If you have any questions or need assistance, our team is always ready to help and provide guidance as necessary, so feel free to reach us any time.
