It is recommended to ground the neutral at various strategic locations in distribution substations, overhead lines and underground cables, distribution transformers, and all loads.
Get QuoteA ground rod should be driven into the ground to a depth of at least 8 feet (2.45 meters).
Ground rods should be spaced at least 6 feet (1.83 meters) apart.
Rebar is steel reinforcement used in concrete to provide strength. The rebar can be used as a grounding rod but is more prone to corrosion.
