UL Listed Industrial Control Panels are constructed and marked to facilitate installation to the National Electrical Code and Canadian Electrical Code. As such, the UL Listing Mark on an Industrial Control Panel is widely recognized and accepted by municipal inspection authorities. The Listing Mark may be applied to a wide variety of designs, ranging from custom built to standardized designs. Industrial Control Panels can be constructed and marked for general use applications as well as a number of special use applications. What is covered by the UL Listing Mark? The UL Listing Mark on an enclosed type Industrial Control Panel covers the enclosure, the components installed within the enclosure, panel-mounted components and components mounted to the outside walls of the enclosure at the manufacturer's facility.
