Conduit Fill Calculator Complaint
The conduit fill calculator complaint needs an option to change the wire size diameter and inner conduit diameter (and maybe an extra option for insulation) rather than using standard sizes; otherwise this calculator should not be used in the field...for example, I needed to see how many 12 Ga. XHHW-2 wires (Kris-Tek) will fit in 3/4", 1", 11/2", and 2" PVC coated galvanized conduit (O-Cal) and found this program says 12 wires in 3/4" is 40% fill...hand calculation shows max 10 wires in 3/4"...which means we would have built the conduit system against NEC requirements and if an inspector caught it, they would make you run an extra pipe which equals more cost to the contractor! Please fix this!
