This may sound ridiculous but I have been asked to stated the code that does not allow for running exposed THHN conductors to a Low Voltage Transformer. The Line Voltage is 277v. I know that THHN should not be run exposed but I am being asked to provide the code section that states this. Its actually difficult to provide.
What I found so far.
300.3(a) Single Conductors - Single conductors specified in Table 310.104(A) shall only be installed where part of a recognized wiring method of Chapter 3.
