Looking for an expert willing to check over and critique a proposed software specification that is designed to (hopefully) help an electrician or electrical designer do the following in a logical, user-friendly, NEC-faithful way:
In AutoCAD, user launches the proposed software utility to guide in selection of conductors for a 3-phase motor load. The utility provides dialog prompts for selection of parameters like:
? Wire type standard ? AWG or MM (metric wire sizes)
? Wire type ? copper or aluminum
? Insulation temp rating
? Optional wire length (for voltage drop calculation)
? Wireway type (affects the voltage drop calculation)
? Power factor (defaults to 0.85 ? affects voltage drop calculation)
? Maximum % voltage drop allowed ? will affect the conductor sizing ? bumping up to next larger conductor size to reduce voltage drop percentage
? Continuous load (default to ?ON? for all motors)
? Fill correction de-rating
? Ambient temp de-rating
? Paralleled wire options (for larger size / larger ampacity runs)
I am a double-E but my experience has been in industrial controls design and now, for the last twenty years, more in the software engineering side of things. I?m looking for someone with current, real-world experience to verify that the ?work-flow? is logical, that it steps through the process the way an electrical designer thinks, it is faithful to NEC, and that I?m not missing anything major.
If this would appeal to anyone out there, please let me know.
Thanks!
Nate Holt.
