Hi,

Is there any mandatory driven requirements for electrical enclosure to require second grounding terminal?
For example if the enclosure is supplied with 3-phase 480Y/277V (Phase1, Phase2, Phase3, GND).
If there is a potential need for and additional grounding terminal driven by Hazardous location codes/standards?
