Let's get into absolutes...(I know some of the information is slightly outdated and not as updated as it should be)

Indiana
Code
Installations must conform to the 2008 edition of the National Electrical Code, with minor amendments.
Local jurisdictions shall not adopt and enforce their own electrical code unless it has been approved by the Fire Prevention and Building Safety Commission/Code Services.
Enforcement
Responsibility for inspection of all construction lies with the local government officials where there is a state approved building department. In areas without an approved local building department, the office of the State Building Commissioner inspects all buildings and structures except those intended for agricultural purposes and one- and two-family dwellings. All plan review is performed centrally, and state field inspectors assist local building officials in code and administrative matters.
Licensing
No state licensing of contractors or journeyman electricians. Most municipalities have contractor licensing requirements.
Reciprocity
None
----------------
What the individual municipality considers electrical or contractor based work would need to be discussed in the area(s) you are intending to do business or what your insurer may or may not cover.
I can't say I agree with a license or division within the trade(s) that would simply encompass "automator" only....at some point that person is going to have to perform skilled work, use test equipment, then determine why something may not work. It's not a clear cut "I'm a programmer only" trade IMHO. Even if the electrical portion is subbed out, how is that person going to relate "X isn't working, why isn't it working" to the EC or LVEC? Quick way to get very expensive when that specialist has to pay for troubleshooting and rewiring, what have you. While I'm going to have to put on my asbestos suit here....we're trying to oversimplify the trade into skilled labor vs. an IT type professional (which IMHO, still should not be doing anything but plugging an cable in between fixed patch points or software/hardware as it pertains to PC's or servers).
