Hello Group, Has anyone heard of a requirement in the National Electrical Code that power supplies which are components of larger systems be approved by an NRTL? I have an inspector telling me this, but our copy of the NEC is 20 years old, and I can't find it, anyway. In this case, the power supply is part of a rack system. It was my understanding that the supply could be evaluated as a component of the system. Is that not true?
