ARTICLE 250 Grounding and Bonding - Mike Holt
www.mikeholt.comArticle 250 covers the grounding requirements for providing a path to the earth to reduce overvoltage from lightning, and the bonding requirements for a low-impedance fault current path back to the source of the electrical supply to facilitate the opera-tion of overcurrent devices in the event of a ground fault.

This is accomplished by a proper factory grounding. Note: Even when the motor is stopped, dangerous voltage is present at the power circuit

qtwork.tudelft.nlSystem grounding or earthing involves the ground connection of power services and separately derived systems. They include generator, transformers, uninterruptible power systems (UPS). The system earthing is the intentional connection of a circuit conductor (typically the neutral on a three phase, four wire system - Protective earth (PE)) to earth.
