• Personnel: for every person who may come in contact with high voltages in the event of a electrical fault
• Equipment: this will insure the equipment in your home or business is protected in the event of a fault.
• Noise Control: this will help eliminate transients from any source. These transients can cause numerous issues from insulation breakdown to sensitive equipment failure.

All ground rods at a facility should be connected where a building’s ground connections come together. This includes all steel, metal water pipes, etc.

These ground rods can be combined at the service entrance to decrease ground resistance.

• In the event of a lightning strike near the facility, the ground voltage for all equipment will rise equally. If there were separate ground connections and this occurred you could have both personnel and equipment safety issues.

The service entrance is the only place where a ground should be connected to a neutral.

• If multiple neutrals are tied to grounds throughout your system, this could cause parallel paths for neutral current which can cause protection circuit misoperation in the facility and equipment.
