•
Better—A grounded #6 AWG minimum copper wire grid mechanically clamped to floor pedestals and
properly bonded to the building or site ground
•
Good—Use the raised floor structure as a ground grid. In this case, the floor must be designed as a ground
grid with bolted down stringers and corrosion resistive plating (to provide low resistance and attachment
points for connection to service entrance ground and HP computer equipment). The use of conductive floor
tiles with this style of grid further enhances ground performance. The structure needs to be mechanically
bonded to a known good ground point
