By understanding the deeper principles behind grounding standards, avoiding common installation pitfalls, and insisting on certified materials from reputable suppliers, you''re not just following
We bond so that metal parts of electrical raceways, cables, enclosures, and equipment are connected to the supply source via an effective ground-fault current path.
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.
Correct grounding of services depends upon understanding the definition and role of the grounded conductor. The neutral conductor is typically the grounded conductor connected to the system''s
Bonding metal parts, such as enclosures and raceways, ensures that they are all continuous on an effective ground-fault current path (EGFCP) that references back to ground (earth).
Each DISTRIBUTION BOX and controller must be grounded. On the US market, a 5.26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used.
The main components of this effective ground-fault current path are made up of the equipment grounding conductors such as bonding jumpers (main, system, supply-side, equipment) and service
You must connect all ground wires together inside the junction box. The NEC says you can use a pigtail, which means twisting the ground wires and adding a short wire to the box or device.
Section 250.148 provides all of the methods permitted for ensuring proper continuity between the equipment grounding conductors when a box is installed, and circuit conductors are spliced within
Common grounding electrodes include rods, plates, pipes, ground rings, metal in-ground support structures and concrete-encased electrodes. All grounding electrodes at each building or
