How to Get a Free Copy of the 2011 National Electric Code (NFPA 70)

How to Get a Free Copy of the 2011 National Electric Code (NFPA 70)

by Fred Fauth (email Fred) | | October 11, 2012 | 26 Comments »

Editors Note: One of our regular readers, Trebor, mentioned how much he enjoyed that we include references to building code in our Pro-Follows. Understanding and following local regulations are an important part of any home improvement project, and Trebor’s comment reminded me that we have these great instructions for obtaining free access to the 2011 NEC. In addition, here are links for free access to the 2012 International Residential Code (IRC) and International Building Code (IBC), and don’t forget to have underground lines located before you dig.

The National Electric Code (NEC) is published by the National Fire Protection Association (NFPA). The NFPA recovers part of its code development costs by selling code books. However, they do make available a limited-use online copy of the 2011 NEC. Unfortunately, the NFPA intentionally makes this free online version difficult to find and use. (If the free online version were easy to use, no one would buy the books!) I tell you how to access the free version below.

New! If you are a Google Plus User and find this how-to helpful, we would appreciate it if you would give us a “+1″ using the button on the left. It tells Google that this information was valuable for us to publish!

Before I give you the steps, you should know that the best way to get access to the code for free is to go to your local library’s reference section. Most libraries will have every recent version of the code on their shelves, and you can make photocopies of the sections you need for your job. I actually used this approach for a recent wall oven installation. I didn’t have any cash on hand for the photocopies, so I took photos with my iPhone and printed them when I got back home. It worked great, and our wall oven is installed to code specifications!

Many districts will be phasing in the 2011 NEC as their electric code standard over the next few years. You should always check with your local Government to determine what code is enforced in your area. For instance, when I started my basement project in 2007, Baltimore Co. MD was still enforcing the 2005 NEC, but had included several amendments. Some jurisdictions don’t use NFPA’s codes at all.

Step by Step Instructions to Get the Code

To obtain limited free access to the NEC, you must sign up for a free NFPA account. Here’s how:

Step 1: Click here to go to the NFPA’s NEC home page.

Step 2: Scroll down the page and click View the 2011 Edition Online. See this image for help.

If you aren’t already logged in (and you likely aren’t at this point), this link will take you to a login or sign-up page.

Step 3: Click the Create an account link.

Step 4: Enter your data into the resulting forms. NOTE: Make sure to use a valid e-mail address. You will need to confirm your membership email address before you can proceed.

Step 5: NFPA will send you an email to confirm your account. Open the email and click the included verify link.

Step 6: Upon completing Step 5, your browser should be taken back to the NFPA site to load the code in a new window. Click the Open link. If your browser does not return to the site, simply go back to the link in Step 1 above, select the link at the bottom of the resulting page for “Read the 2011 online” and sign in with your username and password. You should then be taken to this screen.

NOTE: You MUST have JAVA installed to run the plugin that loads the NEC. If you do not have JAVA installed, your browser should prompt you to install it.

If you’ve been successful, you’ll see the NEC 2011 in a window that looks like this:

Limitations of the Online Version of the NEC

  • Single page scrolling back and forth through the document
  • No search
  • No printing

    While the NFPA certainly has contributed to the safety of occupancies in the US, from my side of things (the fire service side), they seem to be influenced a little bit by a handful of manufacturers. While local jurisdictions adopt large sections of the NFPA “regulations,” the NFPA is just an association, not a governing body. They have no enforcement powers of their own, and most jurisdictions adopt only what is convenient for them to enforce or easy with which to comply themselves.

    For instance, most fire departments will comply with NFPA rules regarding the construction and contents of an apparatus, because federal and state grants usually require so. However, there are almost NO departments that comply with the staffing requirements of the NFPA, which would have 5 men on an engine, and 6 on an aerial apparatus. You’re lucky to get 3 and 3 unless you work for huge departments like FDNY or Chicago.

    Your remarks about the NFPA selling code books is right. They change things sometimes just to make changes.


    Fred Reply:

    Good point to reiterate in the comments…. NFPA is an association… the enforcement of the regulations is a jurisdiction-by-jurisdiction decision. I know that here in Baltimore County, they don’t adopt new code books until a few years after publication. It saves the electricians from having to buy new books and learn new rules.

    Good find. Would still like to have a hard copy but seeing as how i’m not a pro (yet) I can’t really justify the 100 bones. Wonder why they charge so much. (other than to make money of course) Can’t really cost THAT much to change a few words/phrases every 3 years and print a new copy.

    Its not changing a few words in the book that is the problem, its justifying that change, and figuring out that it needs to change.

    Also, make sure to check your state/county/town regulations, as all different levels can add or remove whatever they want.


    Fred Reply:

    Joe, I tend to agree with this. To NFPA’s credit, they release major NEC revisions only every 3 years. While much of the book doesn’t change, that is a sufficient amount of time for new “meat” to roll in and be peer reviewed and commented before becoming code. In between major updates, you can get the minor updates for free on the NFPA site, I believe.

    That’s much better than my college texts, which seemed to be out of date the day after I bought them.

    “What, you have BioChem Edition 11a? I’m sorry, we’re now using 11.a.1, which has entirely new page numbering. You can purchase the new version for $400 at the bookstore.”


    William Reply:

    Ha. College texts is exactly what I thought of when you first mentioned selling NFPA books. Can you sell the old NFPA books back for a quarter of what you initially paid?

    Great discussion. Another resource for changes are continuing education providers. Unlike Maryland, which is county by county, a number of states require courses specifically on the changes. So if you are looking for the top 125 changes based on the proposals and comments, you can take a course for free with a provider like us or anyone else out there. The good ones are only pay after you pass so there is no cost up front. You can sometimes, as in our case, download a pdf of changes for free as well.

    Since you are talking about finding good deals on code books…we ship a code book with tabs for $90, shipping included. You can find our contact information at, or call us at 1-800.443.5233.

    I hope this helps add some ideas for resources you can use.

    All I want is a searchable version. I think it would be very helpful for any handy homeowner. Instead we have to settle for searching the Internet and hoping the forum we stumble across has a code reference on the first page and not the 10th page.

    What is the standard for outlets in a house


    Fred Reply:

    It’s square-footage based, as well as room-type based. And it is dependent on jurisdiction. Look up receptacle requirements in the code and you should see a lot of guides. But, you’ll always need to check with your local jurisdiction to see if they have any modifications.

    What does “limited” free access to the NEC mean?


    Fred Reply:

    If you follow these instructions you’ll get to an NFPA application that allows you to read the NEC online. However, you cannot search, print, copy, past, annotate, or otherwise manipulate the code. Therefore, while it is helpful for answering very directed questions, we find it far easier to either head to the local library to use the code there, or to just pay for a code book. Hope that helps!

    Thanks for this. I’m doing a lot of upgrading to my home’s electrical system and I can only ask my brother in law (he’s an electrician) so many questions.

    I agree that searchable documents would be easier and more convenient. It’s a good resource nonetheless, thanks for sharing.

    I missed this post first time around, so thanks for reposting.

    It seems kind of strange to me that it’s such an arduous process to get a copy of the code. I guess they want you to buy it?

    […] Most jurisdictions follow some variation of the National Electric Code. You can get limited free access to the NEC via NFPA’s web […]

    why no all sizes of electrical cable wire from small diameter size and to bigger size of wire and the current ampacity rating of the wire written in the elec NEC 2008. any electrical technician needs that table to use the correct size of wire and any wiring intallation with out wire size computation and using electrical formula the easy way is you know all size of wire and the equevalent ampere rating.
