Importance of Proper Grounding

 
Stock-102

The main reason for proper grounding is safety for your employees and equipment.

  • Personnel: for any person who may contact high voltages due to electrical fault
  • Equipment: ensures all equipment is protected in the event of a fault.
  • Noise Control: helps eliminate transients, which can cause issues ranging from insulation breakdown to equipment failure.

All ground rods, including metal water pipes, should be connected at the point where a building’s ground connections come together. These ground rods can be combined at the service entrance to decrease ground resistance.

In the event of a lightning strike, separate ground connections could endanger personnel and equipment.

If multiple neutrals are tied to grounds throughout your system, this could cause protection circuits to malfunction.

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