Isn't there an exclusion or lower entry requirement if you have a technical education like engineering degree? Like if not electrical engineering because I guess that would be obvious there should be lower entry bar - but for all others at least somewhat related...
I guess if you want to dabble with installing battery packs with inverters, that's not your typical bachelor of arts who is trying to do so.
Where I am at (rural CO), as long as it can be inspected and meets code, the county is fine- you don't need a blessing. Septic is different (that's a $175 certificate, though). But for electrical all you have to do is meet codes, which isn't really super hard.
