UL Panel Shop

Control Specialists, Inc. has been building control panels for over 30 years. Our panel shop can accommodate any of your control panel needs. Control systems that are required to meet the Underwriters Laboratories 508A specifications for certification and labeling of a complete control package are manufactured at Control Specialists, Inc.

The UL Listing Mark on an industrial control panel provides evidence to satisfy the increasing number of inspection authorities requiring third-party safety certification and your customer demanding the same. The UL Listing Mark may be applied to a wide variety of designs, ranging from one-of-a-kind panels to standardized designs with only minor variations.

UL 508A includes requirements covering industrial control panel enclosures and industrial control panels for general use, as well as specific use panels for industrial machinery, air conditioning and refrigeration, crane control, elevator control, flame control and use as service equipment. UL Listing Marks are available for:

Industrial Control Panel Enclosures

Empty enclosure with one or more enclosure type ratings intended to be used as part of an enclosed ICP at the factory or for field installation.

Enclosed Industrial Control Panels

Industrial control panel installed within a complete enclosure at the panel manufacturer's location.

Open Industrial Control Panels

An industrial control panel that includes factory wiring, field wiring terminals and components mounted on a sub-panel without a complete enclosure. The enclosure is intended to be supplied/completed at the installation.

As a stocking distributor for Hammond enclosures we maintain a broad inventory of controls, junction boxes and fiberglass, sheet metal and stainless steel enclosures.
