Equipment Grounding
Equipment grounding is the bonding together and grounding of all noncurrent carrying (during normal operation) metallic
conduit, equipment enclosures, generator frame, etc.
Equipment grounding provides a permanent, continuous, low-impedance electrical path back to the power source. Proper
grounding practically eliminates "touch potential" hazards and facilitates clearing of protective devices during ground
faults, the equipment grounding system is bonded to the AC system grounded circuit conductor (neutral) at a single point
by a main bonding jumper at the source. See Figure 37 below.
