The Basics of Grounding and Bonding - NFPA Learn the fundamentals of grounding and bonding in electrical systems with NFPA's comprehensive guide for safety and compliance
Grounding and Bonding: How Are the Two Achieved? - NFPA Holistically, according to the 2023 edition of NFPA 70 ®, National Electrical Code ® (NEC ®), grounding and bonding establish a continuous, conductive, and effective ground-fault current path that will help limit any voltages imposed by lightning, line surges, or unintentional energization of non-current-carrying parts
Second Revision No. 7997-NFPA 70-2021 [ Detail ] A conductive path(s) that is part of an effective ground-fault current path and connects normally non-current-carrying metal parts of equipment together and to the system grounded conductor or to the grounding electrode conductor, or both
Statement of Problem and Substantiation for Public Input . . . - NFPA A conductive path(s) installed to connect that is part of an effective ground-fault current path and connects normally non-current-carrying metal parts of equipment together and to the system grounded conductor or to the grounding electrode conductor, or both [70:100] Informational Note No 1:
First Revision No. 26-NFPA 79-2022 [ Detail ] An intentionally constructed, low-impedance electrically conductive path designed and intended to carry current underduring ground-fault conditionsevents from the point of a ground fault on a wiring system to the electrical supply source and that facilitates the operation of the overcurrent protective device or ground-fault detectors [70:,1002023]
