Data centers have some very specific and unique requirements for grounding and bonding that differ significantly from the typical electrical distribution system in other types of facilities. These
The designer will evaluate the sizing of the grounding system and the need for an isolated or bonding ground system separate from the building grounding system.
Each Power Circuit Breaker or Power Transformer having a bushing Voltage Transformer on the tank shall have the Voltage Transformer provided with a separate ground lead, independent of the
After any major change to an electrical distribution system, every three years (maximum), or if ground-related issues are suspected, a qualified electrical contractor or professional engineer should verify
Use equipment grounding conductors sized equal to the phase conductors to decrease circuit impedance and improve the clearing time of overcurrent protective devices. Bond all metal
In flammable and explosive environments, explosion-proof distribution boxes should be selected and explosion-proof treatment should be carried out.
