NEC Ground Wire Size Chart provides standard wire sizing for grounding conductors in electrical systems. It ensures safe fault current paths, compliance with NEC codes, and reliable protection for residential, commercial, and industrial installations.

To find the most optimum ground wire size, you have to consult the ‘NEC Grounding Conduction Size Chart’. What section of the NEC covers grounding? National Electrical Code (NEC) covers the sizes of ground wires in Article 250, Table 250.66 titled ‘Grounding Electrode Conductor For Alternativing Current Systems’.
The rule of sizing ground wires in an electrical circuit is to use same size as hot and neutral wires, or use larger sizes if the circuit breaker or fuse is larger than 60 amps. It ensures accurate protection from electrical hazards and also saves equipment damage What is the standard for ground wire?
If your outdoor wiring runs underground, NEC Article 300.5 sets minimum burial depths — generally 6 to 24 inches, depending on conduit type, voltage, and GFCI protection. For a full breakdown of these requirements, see our dedicated guide: How Deep Does an Electrical Wire Need to Be Buried? 4. Boxes, Splices, and Enclosures (NEC 314, 300.15)
