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 more
Bonding 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 .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 .
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 .

Junction boxes. The junction box (deck box) that connects directly to an underwater permanently installed pool, outdoor spa, or outdoor hot tub luminaire forming shell must be listed as a swimming pool junction box and .What you see inside the box, apart from the usual cable and terminals, is an EarthingNut. EarthingNuts are a simple product designed by an electrician to make troublesome securing .Grounding is the act of connecting the electrical system or equipment to the earth or a conductive object that extends the connection to the earth. Bonding is connecting things together with a conductive path to establish electrical .
Equipment grounding is the connection to the ground of non-current-carrying conductive materials – e.g., cable trays, metallic conduits, junction boxes, transformer casings, and motor frames. The purpose is to limit the conductive material voltage to the ground. 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.
