The NEC defines ground as “the earth.” Grounding is a conductive connection, intentional or accidental, between a circuit or electrical equipment and the ground or some conductive object acting as the ground. In an airplane, for example, the fuselage acts as the ground. Correct grounding provides a low . See moreBonding metal parts entails their connection by a reliable conductor that equalizes their potentials and establishes continuity for ground-fault current. Figure 1 shows two metal . See more

If you use a single equipment bonding jumper to bond two or more raceways, size it per 250.122, based on the rating of the largest circuit overcurrent device. You can install equipment bonding jumpers, bonding jumpers, or bonding conductors inside or .When used as a general purpose junction box or marshalling box, the circuits shall be protected with excess current protection which shall operate within four hours at 1.5 times the designed load current. Figure 3. Figure 4.earthing and bonding requirements for hazardous locations. This article will give an overview of the hazards and problems encountered in those locations and gives information on the performance requirements of earthing and bonding to ensure that the potential for gas ignition, from low voltage electrical sources and equipment, is reduced. 2 . Wiring a junction box - Is this considered an acceptable method of bonding the earths? Soldered banjo, clipped short and clamped to the inside of the enclosure with the gland nut. Photo attached. Problems with the photographed method - zinc plated nut may degrade over time, reducing the integrity of the bond.
Cable armors shall be earthed at both ends for lightning protection i.e. at the junction box and at the control system end. Since the Junction box body and Control system cabinet body is connected to the Safety earth bar, cable armors are ultimately connected to the safety earth.Def. Equipment bonding jumper: The connections between two or more portions of the equipment grounding conductor. Where a metal conduit or tubing serves as bonding means, a single loose connection will impair the fault path. This can result in shock hazard.
