I am being asked by a 3rd party code review team to "Revise construction documents as required to document the total voltage drop across the combination of feeders and branch circuits (drop cannot exceed 5 percent). Refer to ECCCNYS Section C405.9." The project is typical Fire House, no significantly long runs. I don't typically perform voltage drop calculations for a typical building. Has anyone had to comply with this during design phase or prior to construction phase?
