When did Art 90 first appear in the NEC and were there previous NEC's that started at Art. 100?

Thanks
 
A lot of the verbage in Art. 90 appears in similar form as long as the Code has existed.

From the 1897:
The rules are intended to cover, as far as possible, the conditions of modern wiring practices, but it is not claimed from them that they cover all possible contingencies, and contractors and others with conditions where they are at a loss as to application of rules, are invited to confer with the Association on such points.

Sounds a lot like today's 90.1.

A seperate section strictly for definitions appears first in 1923 as Article 1. It was renumbered as Article 100 in 1937.

Article 90 first makes an appearance in 1959, with wording that appeared before it being numbered as you see it today.

The current numbering system was introduced in 1959, with Articles 90 and 100 being the same then as now.

Thank you sir, but this is what I want to know. I recently read NFPA 70E and today started reading the 70E Handbook. All the NFPA 70 publications start at Art. 90.

Why don't these start at Art 1? I posed this question via PM to a very, very old member here that happens to also be a wise guy and he suggested that the 70 books started at Art. 100 and that 90 was added later. This makes sense to me.

So the question is when did Art. 90 first appear?

As I read it, I could only think the dreaded 110.3 ? :smile:

I'm not try'n to qualify anything, you've got the books, I just wanted to comment.

1959, when the current numbering system was adopted. Prior to that, it was called Introduction. The Introduction was started in 1937.

Articles used to be numbered starting with 1. From the beginning through 1930. In 1931, Sections were added to the Articles.

I would have to see this to understand. The question still remains, why start at Art. 90?

Thats so , WELL wrong, The NFPA-70 is the 70th Article of the NFPA.

There is an article 1 see www.nfpa.org, its often forgot that what we follow what is part of a bigger system.

Seems viable to go to 100 verses #1 since they had that already taken!

He's asking about Article 90 in the NEC, not NFPAs Code and/or Standard #90 (of which there are two: 90A Standard for the Installation of Air-Conditioning and Ventilating Systems AND 90B, Standard for the Installation of Warm Air Heating and Air-Conditioning Systems)
 
They probably use 10's instead of 1's for the same reason Basic computer programming numbers each step 10:, 20:, etc.: in case they need to add sub-steps in between, they don't have to renumber everything.
