This may be a stupid question. I have found that the AI apps are notoriously incorrect at calculating the correct conductor size based on type of conductor, voltage drop, ampacity, load current, distance of run, temperature, power factor, and single/three phase. I have found that none of their calculated conductor sizes compares even approximately to the values given in 2020 NEC table 331..16 or Chapter 9, table 8. It appears i will develop my own spread sheet based on fundamentals, i.e., V=IxR and various derivatives. I had hoped AI might save time, but the effort in answer verification takes too long.
Are there any reliable trustworthy apps out there which do a good job at calculating conductor size? When will an AI app be trained on the NEC code?

There used to be a web site called Electrician2.com, also maybe electriciancalculators.com that had a simple wire size calc that was a web page with boxes you type numbers into and it had all the bundling, temp, insulation, termination, voltage drop, etc. but sadly it recently went off line.
 
Asking 'AI' to do these sort of calculations is a poor use of the tool.

These things that we call 'AI' are models of _language_, derived from studying huge samples of human writing. You use 'AI' to ferret out pattern in language or to toss in some randomness yet still get text that fits a pattern.

In the case of wire sizing, you have known rules and calculations that must be applied. These calculations are far better done with a spreadsheet than with 'AI'.

Where 'AI' is best applied for this application is to help write and debug the spreadsheet. AI would be great for searching the NEC to find all relevant code sections. We all know about section 310, but 'AI' would do a better than human job of finding the rare sections that change the required ampacity of a conductor. 'AI' is also helpful chasing down bugs in code. It might work for transcribing the ampacity table into the spreadsheet.

That's what I was thinking. But perhaps I had been overlooking something. It appears i had not been overlooking anything ... a spreadsheet works great.
