Sep 28, 2024 · Key Considerations. The main goal of grounding is to limit voltages caused by lightning, line surges, or accidental contact with higher-voltage lines and to stabilize the voltage during normal operations.
Grounding Electrode System Requirements, based on the 2020 NEC - Mike Holt
A solid understanding of grounding electrode system requirements can prevent cost over-runs, Code violations, and performance failures. To create a grounding electrode system, you bond the various electrodes that are present.
Grounding and Bonding Requirements in the NEC
When grounding or bonding, or performing any electrical work governed by the NEC, remember the purpose of the code: to keep everyone safe. Understanding why you’re applying codes and standards, will help you determine how you perform the work.
Grounding and Bonding - Article 250 , based on the 2017 NEC - Mike Holt
A service neutral conductor must be run from the electric utility power supply with the ungrounded conductors and terminate to the service disconnect neutral terminal [250.24 (C)]. A main bonding jumper [250.24 (B)] must be installed between the service neutral terminal and the service disconnect enclosure [250.28].
