Grounding and bonding systems ensure that electrical systems are safe from electric shock and fires by limiting the voltage imposed by lightning, line surges, or unintentional contact with higher-voltage lines as well as a ground-fault (phase-to-ground fault). Article 250 of the National Electric Code identifies grounding and bonding system installation methods. A properly installed grounding or bonding system for shielding, EMI, static and lightning protection can help prevent cable failures, equipment damage and power quality problems. These systems are also important for personnel protection and compliance with OSHA 1910.301-.308, and .331-.335.
