Bare copper and grounding
Bare, tinned and insulated grounding conductor for ground grids, counterpoise, equipment bonding and substations.
- Conductors, top to bottom
- 4/0 AWG stranded copper
- 2 AWG tinned copper
- 4 AWG solid copper
Applications
Soft-drawn stranded copper is the usual conductor for buried ground grids and rings. Tinned copper is specified for corrosive soils, and copper-clad steel where theft is a concern. Ground rods and connectors are supplied on the same order.
- Substation and plant ground grids
- Building grounding electrode systems
- Equipment and structure bonding
- Solar and storage site grounding
