The materials permitted for the grounding electrode conductor are copper, aluminum, and copper-clad aluminum. Additionally, the NEC allows the items enumerated in Section 250., interior metal piping, metal structural frame, and rebar-type concrete-encased. Learn about the rules for auxiliary, common, and lightning protection electrodes and the materials permitted for grounding electrode conductors. 7 Provide conduit grounding bushings, bonded together and connected to the equipment enclosure on all incoming and outgoing conduits on distribution switchgear and switchboards, distribution panels and on all conduits over 1-1/4” diameter at all panelboards, pull boxes and equipment. Whether you're a seasoned pro or just starting out, this comprehensive guide will give you practical. Power from factory ground must be installed by a qualified electrician. Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding of the units: Attach a ground wire from one of. IPMENT, STRUCTURES, ETC. IN ELECTRICAL STATIONS INCLUDING TRANSMISSION AND DISTRIBUTION SUBSTAT GR THAN 8 FT FROM THE FENCE. THE FENCE SHALL BE GROUNDED SEPARATELY FROM THE GRID UNLESS OTHERWISE NOTED ON THE A PROPRIATE PROJECT DRAWING.
Connect the conductor from the panel ground bus or connector at the source to all items to which the conduits or raceways connect. Bond to a ground lug within each panel, box or equipment.
This reference is intended for preliminary optical-network research. Compatibility, link budgets, installation methods, test limits and applicable standards must be verified for the specific project.
