Preventing Electrical Shocks With Proper Grounding Techniques

An estimated 58 people lose their life each week as a result of electric shock. In an electrical system, the grounding and bonding system is the primary protection against electrical shock hazards. It provides a low resistance path to ground to protect against electrical faults. The effective ground-fault current path ensures facilitation of overcurrent device operation under ground-fault conditions. The earth is not to be considered as an effective ground-fault current path [see 250.4(A)(5)]. Using proper grounding and bonding techniques, testing and maintaining a good electrical ground and installing protection devices are the best ways to protect people and equipment from electrical shock.
