My company is building a NEMA 4R box that will be hardwired with conduit. Inside will be a 120vac to 12vdc convertor and a small black wifi to ble device. I believe Section 725-54(a)(1) would apply and we would need a barrier between the voltages. Plus it would be safer for service to have the high voltage protected anyways. However my company likes to save money and everything has to be justified beyond belief. So curious if I have the right code and if anything else that could come into play.
