These steps are commonly referred to as bonding and grounding. Bonding and Grounding The process of bonding and grounding can best be described as creating an electrical pathway between a dispensing container, a receiving container and an earth ground. This pathway allows static electricity to safely dissipate into the ground.

Ground or earth in a mains electrical wiring system is a conductor that provides a low impedance path to the earth to prevent hazardous voltages from appearing on equipment. Earthing is more commonly used in Britain, European and most of the commonwealth countries standards (IEC, IS), while Grounding is the word used in North American standards (NEC, IEEE, ANSI, UL).
Portable Earthing Equipment are safety equipment designed for discharging grounding of dead equipment. The system is designed for high fault levels so that even if during shut downs, when technicians are on the job, by mistake if the supply is switched ON, the Portable Earthing Equipment saves human life as well as equipment under maintenance.
