18 — ElectriCalc Pro
[Set] [Grnd]
— Equipment Ground (EqGrnd)
This function uses NEC Table 250-122
to compute the minimum equipment
grounding conductor size, given an
entered amperage rating or setting for a
over-current device up line (i.e., 300
[Set] [Grnd]).
NOTE: This function deviates from the
NEC Table 250-122 in that 1250 MCM
AL is used instead of 1200 as specified
in NEC Table 250-122.
