Hi y'all,

A simple question:

When using 4 AWG (copper, stranded) as a grounding electrode conductor, what burial depth is required? This is for a residential occupancy.

Is it 24 inches, based on column 1 (direct burial cables or conductors) and the first row ("all locations not specified below") (the table is for "0 to 600 volts")?

Would appreciate your views.
