As I understand it UL508A requires that all instrial control panels be marked with the overall SCCR of the panel and a method is established for arriving at this rating. I also understand that the US NEC states that a panel must have an SCCR greater than the available fault current available in the system into which the panel is being installed.
My question is I do not see anywhere in the Canadian Electrical Code that this is a requirement. Does anyone know the relevent section of the CEC?
