Can an insulated copper conductor be used for a ground grid?

E&S Grounding Solutions Jan 8, 2019 0 108

You may not use insulated wire for your below-grade ground system. This would be a clear violation of every imaginable code, standard, and regulation, including the National Electrical Code (Article 250.52(4) and numerous others) and the Canadian Electrical Code.

Why use a bare conductor for below ground grounding instead of an insulated conductor?

E&S Grounding Solutions Mar 3, 2018 0 84

The reason for using a bare copper conductor below-grade is to maximize the “leakage current” capacity and to maximize the sphere-of-influence of the grounding system.
