Grounding Takeoff

nfpa-70_250_grounding

This script is intended to cover both electrical and telecom grounding in lieu of detail sufficient for standard takeoff (e.g. a grounding riser).

Note that the material provided in this system is intended to be budgetary, not especially consistent with the actual install.
