I have 13.8kv-480/277 Secondary Unit substation in an electrical room with other low voltage equipment (panels and distribution panels). As this is a dedicated electrical room, I assume that this is considered "Accessible to qualified persons only"-110.31 (b)(1).
110.34. States that: Where switches,cutouts, or other equipment operating at 600 Volts, nominal, or less are installed in a vault, room, or enclosure where there are exposed live parts or exposed wiring operating at over 600Volts, nominal, the high-voltage equipment shall be effectively separated from the low voltage equipment by a suitable partition, fence or screen
Do I need this separation, or am I misinterpreting? Exposed live parts (MV switch, transformer?)
