These are the components designed to supervise and ensure proper functioning of the controlled loads or equipment. The UL evaluation standards also don’t extend to the adequacy of the controls and protective devices contained within the control panel. Likewise, it excludes any components that are field-installed on or within the control panel itself. In addition, the control panel is considered and evaluated on its own from any equipment mounted in a remote location away from it, even those connected via a wiring system. Note that while its list of inclusions is far-reaching, 508A does not cover evaluation of the equipment that the control panel controls, such as: The assemblies may also include a combination of power and control circuit components, along with all associated wiring and terminals. Or, they may consist of control circuit components, such as push-buttons, pilot lights, or control relays. Buttons, switches, timers, and controllers.Industrial control parts included under 508A include assemblies of two or more power circuit components. Commercial and residential swimming pools and in-ground spas.In terms of industrial control panel equipment, Standard 508A covers those installed to provide control of permanent electrical equipment found at: The standards also cover industrial machinery, such as: In addition to basic industrial control equipment, UL 508A also covers industrial control panel enclosures and control panels designed to support flame safety supervision over the following types of equipment: The ambient temperature at the installation location is 40☌ (104☏) or cooler.The installation will follow the National Electrical Code, ANSI/NFPA 70 standards.

These systems will operate from a voltage of no more than 1,000 watts.With both installation formats, the following assumptions are in place from the onset: This makes it a piece of “open type equipment.” In this case, the assembly fits into an enclosure that others provide, or it’s at the installation site. Or, they can arrange the panel onto a mounting panel.

First, they can install it inside of an enclosure, which makes the panel an “enclosed type” of equipment. Note that users can install a control panel in one of two ways. Scope of SectionĪt its core, UL 508A sets parameters for the design, control, and use of industrial control panels intended for general use within the industry.
