EXCERPT: What is the purpose of UL 508A?
UL 508A provides the requirements for industrial control panels operating at nominal voltages of 1,000 Volts or less and in ambient temperatures that do not exceed 40°C (104°F). It covers equipment intended for general industrial uses and installed in ordinary locations in accordance with the NEC. UL 508A applies to two or more power circuit components (motor controllers, circuit breakers, control circuit components, etc…) with associated wiring and terminals. An industrial control panel does not include an evaluation of loads connected to power circuits such as motors, lighting, etc. It also does not cover fire pump controllers or equipment connected to/installed in hazardous (classified) locations. For fire pump controllers or hazardous (classified) locations, see UL 218 or UL 1203 and UL 698A respectively.
