Hello Mitchell, Industrial Control Panel is defined in Article 100 as: An assembly of two or more components consisting of one of the following:
(1) Power circuit components only, such as motors controllers, overload relays, fused disconnect switches, and circuit breakers; (2) Control circuit components only, such as push buttons, pilot lights, selector switches, timers, switches, and control relays; (3) A combination of power and control circuit components. These components, with associated wiring and terminals, are mounted on, or contained within and enclosure or mounted on a subpanel.
There is nothing in the definition or in Article 409 that prohibits the installation or use of an Industrial Control Panel in a dwelling unit. Part II of Article 409 and the product installation instructions will govern how and where it is installed.
