Who Had the Strictest Electrical Codes ?

I say the City of Los Angeles. Until the Federal Housing Authority required Romex to build cheaper housing. Then changed to aluminum "Romex".

Chicago still has very limited use of any cable wiring methods and dwelling units are all EMT.

That is very interesting ... I thought that in order to get federal money today, the jurisdiction had to adopt federal guidelines.

maybe the got the courage to tell not take the dirty money.
I am surprised oregon has a hard test compared to national average. Though don't usually add too much to the code, they take out alot like all the dumb new GFCI requirements.

Is there any federal code when it comes to electrical codes?

federal monies helping fund non federal projects is not necessarily the same thing as building a federally owned facility where they may not necessarily need to comply with local jurisdictions and their codes. I've worked on projects where federal funds were used to fund the project or portions of it, most the red tape was with labor laws but installation codes was still per local jurisdictions.
