Article 100 Definitions. Industrial Control Panel.
Code Change Summary: The definition of an “Industrial Control Panel” has been relocated from Article 409 to Article 100.
When a term is used in more than one code article, the definition is sent to Article 100. Relocating the definition is not near as significant as what the definition really describes.
Not all industrial control panels are made by an equipment manufacturer. Many industrial control panels are created in the field by electrician. An industrial control panel can be made simply by inserting two lighting contactors into an enclosure. Any time an industrial control panel is created, the rules in Article 409 must be followed.
409.110: Industrial control panels must be marked with the manufacturer’s name, supply voltage, number of phases, frequency, full load current and the short circuit current rating.
409.22: Industrial control panels cannot be installed in a location of the circuit where the available fault current is greater than the short circuit current rating marked on the industrial control panel.
