I have a question on a Class I Division 2 junction box. Here is the following back ground information. We are building a machine that has a NEMA 4X junction box with only terminals. It will be wired using RMC and devices on the machine will be 24 VDC and 4-20 mADC instruments. The customer would like to mount a stainless steel nameplate on this enclosure by drilling holes and mount it to the enclosure with stainless steel screws. I looked though Articles 500, 501 and other sources and can’t find if this is acceptable in a hazardous location. I do not see were stainless steel screws and holes is a listed or a approved method. The screws will penetrate the enclosure in a Class I Div. 2 area. What is your opinion?
