From the links and information earlier in this post you should have seen that the governing codes depend upon where you live in Cass County and under what circumstances they are being applied. If you live in an unincorporated part of the County, rather than the NEC, the electrical section of the International Residential Code(IRC) might apply to your location (the electrical section of the IRC is generally based on the NEC).
You first have to determine what code applies to your location and situation and I would still recommend contacting either the Beardstown Code Official (who might know about the unincorporated area anyway) or the Cass County Zoning Officer.
Once you know what applies, get someone qualified who can document the violations based on the specific chapters and sections of the applicable Code, so that you have a coherent case to present.
In case the IRC does apply to your location/situation, the link to its electrical section is:
