How To Build a Motor Starter in Accordance With UL 508A
UL 508A allows control panel builders to apply a UL label to their finished assemblies without having to run those assemblies through specific UL testing. As long as they adhere to the standard’s requirements, builders can put the UL label on the finished product and save money by not having to send it to UL for testing. According to UL, the UL 508A standard applies to industrial control panels intended for general industrial use that operate from a voltage of 1000 volts or less.
