Learning the NEC for the NON-Professional

handyman78

Unless you are a professional that needs to reference it regularly and can justify all types of installations it is not a worthwhile purchase for the masses. You can always pose specific questions to sites like this and get an answer from many professionals or someone who will look an issue up for you.

The supreme court ruled that laws can't be copyrighted. You can get all the NECs here free in PDF form.


Mods maybe you want to put this resource in a sticky?

Caution on the "Wiring a House" book. The posted link to Amazon is OK because that is the second edition (2002). The new third edition has been recalled by the CPSC (Consumer Product Safety Commission) due to Safety related errors.

I don't see one for MA

Alaska has adopted 2008, I downloaded their PDF which has NEC 2008
Thanks

Gigs

Just find out what NEC cycle you are on and download one for a state that is on the same NEC.

The way that the NEC is incorporated is that the beginning of the PDF has state specific amendments, and then the rest of the PDF is the unmodified NEC just like if you were to have bought it.

Some of the states have nicer scanned and OCRed copies than others, so try a few different states if you don't like the quality of the first one you try.

That's debatable when polarized receptacles first came out they were mostly wired with the ground pin UP
The NEC doesn't say but Mike Holt recommends the ground pin installed UP.

I have the 2008 PDF and it's only 7 MB. Not sure why the bulk resources versions are over 100 MB!

Just curious... Say your jurisdiction requires 1999... or 1979... or whatever. If you do your work to NEC 2008 standards are you necessarily in conflict with other earlier years?

And if so, if you do live in one of these old-school jurisdictions, is there a way to argue that your 2008 NEC install is superior?

BTW - my jurisdiction requires 2005 compliance and I am sure will update soon.

Because the states scan the book so it's raster. It's a picture of the pages instead of the text of the pages.

But there's OCR text under the image so you can still copy and paste in most PDF readers.

Basically you see a picture of the page but if you copy and paste it's OCR.

Anyway yeah that's why they are so large.

Clutchcargo: Don't regret buying the book. It's nice to have even if you can get free copies.

Gigs

Usually they do not conflict in that way. Most code changes are backward compatible.

I see... so what's the advantage of that?

p.s.: I'd much rather have the book. I can't stand to read a computer screen for long periods of time. Here in forums it's a quick glance, but I couldn't read a novel on a computer. My eyes would explode.
