# 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.
