Ground Conductor Wire Size - Calculated Industries ElectriCalc Pro 5060 User Manual

Ground Conductor Wire Size

You can use single or multiple service
entrance conductor(s) to find the
grounding electrode conductor for AC
systems. When using multiple conduc-
tors, the ElectriCalc Pro uses the
equivalent circular mils to find the
grounding electrode conductor (based
on NEC Table 250-66).
Find the grounding electrode conductor
wire size required when 2/0 is the larg-
est 3-phase 75°C copper service-
entrance conductor being used. What
is the equivalent aluminum size? What
is the equivalent circular mils?
