OK to use latest NEC code?

[SynergyMike]

Hi All,

I'm finally preparing to build my detached workshop/garage and am trying to do as much of it myself as possible. On the topic of electrical, I am wanting to educate myself on the electrical codes before I start into that part in the next 2-3 months.

My question is: Is it OK/encouraged/discouraged to adhere to the latest (NEC 2017) electrical code or use the code that my city has adopted - which is NEC 2011?

Many thanks!

Why not ask your city inspector's office?

You can go above the adopted code but if the newest NEC has dropped a requirement then you would need to follow the 2011 that is being used.

pattenp is right. That is authority having jurisdiction over your installation.

But, in general, the latest NEC update is the best one to use. If you do something that is illegal in 2014 but perfectly legal in the 2017 edition, I can't imagine an inspector holding you to the flames. Changes usually become more stringent/safe, clear up ambiguous wording or fix mistakes and/or add exceptions to the rule.

Arizona shows no Statewide adoption of the NEC, so PattenP is dead on.
Contact your local Building Dept.

Unless you have some "special" wiring requirements, and DIY electrical book would probably be good enough. Inspectors with look for proper breaker/wire size, adequate wire support on horizontal and vertical runs, minimum height above the floor for boxes, boxes properly secured with wire hold down outside the box and proper installation of GFI outlets/breakers.

240V circuits are pretty much the same.

Don't over complicate it !

According to the Mike Holt website, https://www.mikeholt.com/technical-nec-menu.php AZ has no statewide NEC adoption, it's up to the local jurisdiction to adopt what they wish, I would find out what was adopted locally and conform to it.

Ask your AHJ...

I will agree with a different book for basic learnin. The code is not really a how to manual.

Yeah, I sure will, but was going to buy a "how-to" book over the weekend and you can find them written for certain year NEC compliance. Thanks!

Agree with this totally. I've read some of the code books and can only really understand a [small] percentage of what they say. I figured a good 'how-to' book + the code book + advice from a local electrician should do it.

Exactly.

The NFPA 70 NEC code is not a how to manual.

But the NFPA nec handbook is somewhat of a how to with expanded text, commentary and pics.

Code check makes some really handy 'illustrated guides' on a number of different subjects that I have found to be very handy over the years

The electrical version is only $15

Git,

Thanks for the referral. I've ordered that one & Wiring a House 4th edition by Rex Cauldwell. That should keep me busy for a couple nights.

2011? You really want to deal with AFCI everywhere and a dedicated neutral in all switch boxes? Get it done per the 2011 version before they adopt something newer and cost you a whole lot of money. Some stuff is good to have, and some stuff is just a money grab.

As others said, it depends. I design modular homes for multiple states. I prefer to design to the most recent code to make my life easier. Some locations will absolutely not accept anything but the adopted code. Call your local guy.

As Daedalus said, you'll probably have a way easier and cheaper experience building to the adopted code with little to no risk to your safety. It's not like everywhere that builds to the 2011 code is electrocuting people and burning to the ground. There is a ton of scope creep in code updates.
