NEC, 1930's and older PDF

[Wire-Smith]

Does anyone happen to know where i might be able to find PDF's or some sort of digital copy of 1930's and or older National Electrical Codes? I may be remembering incorrectly but I thought I ran across some before, I'm trying to follow the progression of a few specific code sections.


Thank you

I have a few old books what are you wanting to look up?

Somewhere in my archives I've got the 1897 - 1920 in PDF. I'd have to scrounge around to find them, though.

1901 NEC 35 pages. Says "Appendix I". I could be missing some.
It is about 1 MB.

If, when, you have time to screw it, I'm interested

OK, I lied.

It's 1881-1918. I'm upload the zip file to a fileshare site now.

In the meantime, maybe this can help you.

I don't think NFPA released any digital editions until at least somewhere around 1990 - 1999

They didn't, but I've scanned in some of the old ones I have. Plus, Mike has done the same with some of the kids. And I've rounded up others from various sources.

The upload failed. So I'm trying plan B.

Are you saying PDF may have been an option in 1930 they just chose not to use it?

Yes, they did. However, their morse code key didn't work. :lol:

Thanks,


1933, 1935, 1937 or the closest you have.


-what is currently 310.15(B)(7) in 2017 NEC, in 65' it was 310-14 table note. Resi service conductor overrating. this is the only one that's probably worth asking about, I believe I have narrowed down the introduction of this section to around this time period using the report on NFPA Free Access.

So If you have something better to do don't worry about the next two, but if you want I am also searching for these.

-what is 310.10(H) in 17' and was 310-10 in 65'. paralleling

-what is 250.64(E) in 17' and was 250-92 in 65'. ground conductor enclosure must be electrically continuous


Thanks a bunch

If anyone happens to have a copy of or information about the utility study that was used for the substantiation of that section, that would be awesome as well, that includes any NEC reports or articles about it, I have read what Free Access has so far.

Thanks

Are you asking for the actual language of the '65 references? Or for '33/'35/'37 references?

I snagged that right up when you posted it before, that is awesome, thank you very much

33' 35' 37', I have the 65'. I just used the 65' reference to hopefully get you closer in the older books.


Thanks

I can't find the language of 2017's 310.15(B)(7) prior to 1975.

I equate it to the table note, in 65' table 310-14 note
