ROUNDING
This section provides requirements and procedures for grounding a PG-FlexPlus field cabinet in single- or multiple-
field cabinet configurations.
The field cabinet grounding system has been designed to protect personnel from shock hazards, to protect the
equipment from lightning transients and other electronic noise conducted into the field cabinet, and to reduce
electronic noise emissions to the environment. The field cabinet structure serves as a continuous ground bus,
providing multiple points for grounding of internal wiring and hardware. The equipment rack uprights are the primary
equipment-grounding members of the field cabinet structure.
In most areas, the standard grounding configuration that uses two ground rods is sufficient. In areas of high lightning
activity or low ground conductivity, a ground ring or other means should be used to increase the effectiveness of the
grounding system.
Equipment and Materials Required for Field Cabinet Grounding
The following materials are required for the standard grounding configuration.
• 2 ground rods, 8 feet (2.4 m) long per NEC Code, Section 250-83
• 20 feet (7 m) of 6 AWG (16 mm
• 2 ground rod clamps [for 6 AWG (16 mm
The following additional materials are only needed when installing the optional ground ring around a PG-FlexPlus
field cabinet.
• 26 feet (8 m) of 2 AWG (35 mm
• 2 ground rod clamps [for 2 AWG (35 mm
Local practices and requirements may require additional materials.
