New NEC Forum
JoeTedesco has requested an NEC sub forum for the electrical topic and since we now have someone who can actually answer these questions I figured it would be a good thing for everyone.
I hope everyone enjoys

I would like to start off by discussing residential electrical inspections, red tags, and common interpretations related to getting the underground, rough, and final installations inspected and approved by the AHJ.
Maybe a list of the most common problems or questions will be a good starting point. Go for it, or let me post what I believe to be important issues associated with inspections.

I like the idea but I think that you may have PO'd md. I have learned a lot from his input, it would be a shame to lose him.

Nope, won't PO me one bit. Joe Todesco is one of my heros. He's a pretty famous heavy in my trade. I can't tell you how pleased I am.
Some of you guys might already know him, because he's the electrical guy on the JLC forum site.

Joe just suggested this forum ... he's not taking it over or anything like that. Maybe I should have written my post a different way.
This is just one more sub forum on ContractorTalk.com.
I'm sure a lot of people will participate in this forum.

I think so too.
It is very common to have a dedicated NEC forum aside from the general nature trade specific forums.

As ContractorTalk.com grows you are going to be seeing more and more sub forums within topics. I think it's a natural progression.

I saw that md had edited his post and ASSUMED that he was insulted, my bad. I apologize for that assumption. BTW, I read all of the electrical posts.

Section 110.3 in the 2005 NEC is very important!
Please look here for free access to the 2005 NEC:
http://www.nfpa.org/aboutthecodes/Ab....asp?DocNum=70
Also, if anyone wants a copy of the "2006 UL Directory (White Book)" that gives most of the instructions for electrical equipment, go to
http://www.ul.com and download that publication.
It has many useful bits of information, for example, special GFPE for electrical circuits and "line and load" markings on CB's.

What happened to that message and my reply?
We were discussing the installation of metered and un metered service entrance conductors on the farm "may pole" in the same raceway and I suggested that the utility company may have a restriction not uncommon.
Was there a problem with the reference I posted from the NEC to 230.7?

I saw the other link and commented there.
I think this electrical forum is full of some interesting information.

glad you are here joe
there is another thread about line and load designation of unmarked breaker disconnects vis-a-vis top or bottom feed, related rules
Got any input on bottom feeding of disconnects?
A search found Mike Holt says unlabeled breakers can be fed either end

Bottom feeding of disconnects leaves the blades hot, and we know that, reminds me of an inspection in a Mall where I found this on the installation for about 3 disconnects and said sorry I cannot release the meter, the dude asked why, and I said you go ahead and figure that out, about a week later he called and begged me to forgive the error, said is was the helper who done the job.

Yeah, yeah, thanks ... blade type disconnects are obvious.
How about unmarked breaker type disconnects with inherent lugs on both ends?
