National Electrical code

There is no "national" electrical code that applies universally to all 50 states. The NEC can be adopted by local jurisdictions if they so choose. Many states or cities adopt their own modified version of the NEC although none are required to do so.
 
Don't try "it's NATIONAL" in NYC or Chicago, they have their own codes basically untethered to the NEC.
NYC finally moved away from their antiquated electrical code and had been under the 2008 NEC with amendments for about 15 years. They just moved on to the 2020 NEC with amendments. Prior to that their home brewed electrical code was horrible. I still have my 1987 NYC codebook from my apprenticeship. Not sure about Chicago.
 
Just a friendly reminder that the code we adhere to is NATIONAL,so no need to say what parts of the nation allow what. All inclusive national electric code.
"This Code is purely advisory as far as NFPA is concerned. It is made available for a wide variety of
both public and private uses in the interest of life and property protection. These include both use in
law and for regulatory purposes and use in private self-regulation and standardization activities such
as insurance underwriting, building and facilities construction and management, and product
testing and certification."
 
There is at least one state (Arizona?) that has not adopted the NEC at all. They let each municipality adopt their own code.
Correction: there are 4 states

It is not an enforceable code until adopted by a unit of government with the power to adopt building codes. When that unit of government adopts the code published by the NFPA, there are often state or local amendments the either add additional rules or eliminate some rule.

The map is wrong for Illinois...the state has adopted the 2008 NEC, but that only applies where there is not a county or city adoption. A county of city may adopt any edition, including those prior to the 2008 code.
However without a county of city adoption, there is no enforcement or permits, even though the state requires compliance with the 2008.

The city I live near requires permits and inspects to the 2008 code, but I don’t think they’ve formally adopted it.

I not sure how that works where a city issues permits and inspects without adopting a code. However, If they don't have an electrical commission, they cannot issue permits or inspect per state law.
(65 ILCS 5/11-37-2) (from Ch. 24, par. 11-37-2)
Sec. 11-37-2. Any municipality by ordinance may regulate the installation,alteration, and use of all electrical equipment as provided in this Division 37 and may establish an electrical inspection department for this regulation.
Each municipality which establishes such an electrical inspection department shall also establish an electrical commission, consisting of 6members as follows: The superintendent of electricity or the chief electrical inspector of the municipality shall be a member and ex officio chairman of the commission; of the other 5 members, one shall be a registered professional engineer, one an electrical contractor, one a journeyman electrician, one a representative of an inspection bureau maintained by the fire underwriters, if such a representative resides in the municipality, and if no such representative resides in the municipality then the chief of the fire department, and one representative of an electricity supply company. If there is no person residing in the municipality who is qualified under any one of these descriptions, the mayor or president of the municipality may appoint some other person to fill that position. All members of the electrical commission shall be appointed by the mayor or president of the municipality with the advice and consent of the corporate authorities.

Interesting. I’m going to nose around and see if I can find out the actual situation. There’s definitely no commission of any kind. The city has 2 inspectors, one electrical and one that covers everything else.

Yes, we are the wild west for electrical code. Although the NEC is adopted pretty much everywhere, everyone is on a different version.

And don't get me started on building codes. Most places adopt some version of the IBC, but technically the State Fire Marshall's office enforces the 2015 life safety code for anywhere that hasn't adopted their own code.

State agencies also license some facilities like health care, even where there are local codes. So sometimes we have to check for compliance with multiple codes.

Gotta remember 20 different versions of 20 different codes and what applies where.
