NFPA 30 does not require that the cabinet itself be grounded. Many manufacturers provide a grounding screw on their cabinets as a convenience to the user. The user can connect this screw to a building ground and use the cabinet-mounted ground point as needed to ground individual containers from which liquids are dispensed.
