Wayne, I am quite surprised you would feel comfortable pointing out "violations" if you do not have a code book.

You seem to be a computer guy, I would suggest getting the code on CD-ROM


2002 NEC
334.10(A) Type NM. Type NM cable shall be permitted as follows:
(1) For both exposed and concealed work in normally dry locations except as prohibited in 334.10(3).
334.10(3) is not a factor in this installation.

When I was teaching apprentices, if a guy showed up for a seminar without his codebook, I wouldn't even talk to him. He was "persona non grata". Word soon got around. :)

A word of advice. Don't mess with the guys on this forum unless you are absolutely sure of yourself.

Protection from physical damage can be a judgement call, and if you feel that the NM cable at this panel is in jeopardy from damage, then what about the panel itself? Being able to touch something does not make it subject to physical damage (another term/phrase not defined in the NEC).

Also, because an installation method does not appeal to you does not make it a code violation. In my classes I have 'Pipe' guys, 'NM' guys, and 'AC'cable guys. It gets to be fun discussing how they feel about each other, and I hope that I help them to understand that all three practices have their place.

One more thing ... please don't get Ed mad, we need his drawings

Ed,
Point well taken. I'll have my code books soon enough. Due to my disability I am still doing most of my shopping online. Should be here any day. Lots of stuff on order. Regrouping after a workplace injury. Setting up my office right now while I get my legs back. Thank you for your comments, tips, and advice during this time of new beginnings for me.

Again, that is a beautiful job. I would just cover up the low-hanging NM. Pierre, panel boxes are protected until you take the cover off. To do that you have to make a conscious decision to remove the screws. I'm not an apprentice. I'm not in a class. I'm just here to discuss things in this forum. I am very grateful for all your constructive replies. Feel free to speak your mind. It goes both ways.

Warmly,
../Wayne

Wayne, you mentioned 334.15(B), so here is 334.15.

2002 NEC
334.15 Exposed Work.

In exposed work, except as provided in 300.11(A), the cable shall be installed as specified in 334.15(A) through (C).

(A) To Follow Surface. The cable shall closely follow the surface of the building finish or of running boards.

(B) Protection from Physical Damage. The cable shall be protected from physical damage where necessary by conduit, electrical metallic tubing, Schedule 80 PVC rigid nonmetallic conduit, pipe, guard strips, listed surface metal or nonmetallic raceway, or other means. Where passing through a floor, the cable shall be enclosed in rigid metal conduit, intermediate metal conduit, electrical metallic tubing, Schedule 80 PVC rigid nonmetallic conduit, listed surface metal or nonmetallic raceway, or other metal pipe extending at least 150 mm (6 in.) above the floor.

(C) In Unfinished Basements. Where the cable is run at angles with joists in unfinished basements, it shall be permissible to secure cables not smaller than two 6 AWG or three 8 AWG conductors directly to the lower edges of the joists. Smaller cables shall be run either through bored holes in joists or on running boards.
Please take a look at this part of 334.15(B)

Where passing through a floor, the cable shall be enclosed in rigid metal conduit, intermediate metal conduit, electrical metallic tubing, Schedule 80 PVC rigid nonmetallic conduit, listed surface metal or nonmetallic raceway, or other metal pipe extending at least 150 mm (6 in.) above the floor.
This makes it perfectly clear that the NEC is not "absolutely confident that Romex within reach is subject to damage", once you have come up at least 6" with one of the raceways listed you could go on with the NM on the surface.

What about SE coming down the side of a house to a meter and then out of the bottom of a the meter in through the sill and basement to the panel, is this a violation?

What I describe here is done every day in the New England States, are you saying all these inspectors are wrong in passing these services?

That's great if you have a code book on the way, but until it arrives you are no different from the DIYs, that you seem to have a problem with.

Obviously you are more then welcome to say "In my opinion" NM exposed is not the way I like to see a job done, but I would say you have no business saying "that is a violation" with out some code refernces to back it up.

Remember with close to 10,000 members there will be some that are just getting started in the trade and IMO you are doing them a disservice :( posting opinions as facts.

JMO, Bob

By the way, you do realize that few of us that post are new to this trade, you did see Ed's picture, do you think he has never taken an inspection before? :D

You sound very energenic, ambitious and enthusiastic about this industry, and that is a good thing. We all have our 'opinions' and when we 'stray' :roll: , this forum will let us know. When there is a term used in the NEC that is not defined per say, then there is some interpretation left open to discussion.
You have mentioned that you are not new to this industry, but let me explain one of the important things I have learned from this forum.

I have close to 30 years in construction and a college degree in constuction. In my situation I have performed all my work in a 20 mile radius, a very small piece of the pie.
In the last 4 years I have paid more attention to what is being performed outside of my comfortable little zone. Also these forums have been an eye opener! I have changed my focus to teaching in the electrical field, so now I am traveling to more locations and like Joe Tedesco, I always have a camera in hand and a eye out for 'different' kinds of the same kind of work that I am use to.
An important lesson learned is 'my way is not the only way'. As they say, there is more than one way to skin a cat!
The lesson to be learned... sometimes when we have a strong opinion be careful, we may be treading on someone elses foot.
Good Luck, sorry to hear about your situation. I think I can say that all here will help if you want to be helped.

This Work of Art is obviously a test panel used in classrooms to teach students how to terminate a panel!

You may want to look at what Ed said about this panel and his involvement on page one of this thread.

Wrong. This is the service in the house of a one of my friends.

Panel.jpg


I've discovered that an extra hour spent on a job, tidying up the few
parts of the installation that the customer, and their friends can see, pays off.
I've never been out of work since I started in 1953.
It doesn't take much longer, perhaps 20 to 30 minutes, to straighten
the cables, and drive a couple of dozen staples.

Try it, you'll like the results.

Good point! And lovely it is. We can all learn something from artistry like that. That is true craftsmanship and done with pride.

Pierre said: The lesson to be learned... sometimes when we have a strong opinion be careful, we may be treading on someone else's foot.
Point well taken. My post was poorly written and tone of my post was easily construed as negative.

Here is my take on forums and why I choose to participate: I have beliefs. I only say what I believe. Sometimes in haste or brevity typed words cannot convey my true and complete belief. That being said I still take the risk and share my beliefs. This opens up my beliefs to constructive criticism. If I share my belief and it goes unchallenged the lack of challenge validates my belief. If I am challenged it forces me to revisit the source of my belief. If the challenge is compelling I modify my belief and my mortal mind is enhanced. When I offer up a belief it's not the final word nor am I necessarily trying to compel anyone to convert to my belief. This forum is a venue for seeking answers, sharing beliefs, and coming to a satisfactory understanding. It's all about the questions and it's all about the brainstorming. Through that process the answers and solutions will crystallize. One one hand my brain is full of reams of useful and useless knowledge. On the other hand no matter how much I know, in the big picture my brain does not contain a nano-thought of everything. There is too much knowledge for one person to know-it-all. Thanks to the Internet and this forum we can combine our brain cells to create a brain matrix that is larger than the sum of its parts. The Internet has networked the brain and its contents.

When I state that Romex should be covered up, it's a challenge to validate or dispute my statement. You can validate my belief with silence or with facts, or you can challenge it with facts. Either one will steer me to the proper belief and solution. I am here to learn. I am open-minded. I do have my beliefs. Beliefs are a moving target. Please help me to hone my beliefs.

Nothing personal. No offense intended. My apologies for any ill will created. It's all about what's safe and establishing standard trade practices. I smile every time this picture is reposted. I smile because it's beautiful!

Ed,
You are a man after my own heart. When it comes to craftsmanship you and I are on the same page. Is the name of your company "Electricity as an Art Form"? I mean that with the utmost respect & compliments.
../Wayne

PS: I'm going to talk to my AHJ about the Romex protection. My beliefs are dated, dusty, and rusty. Thanks for helping me dust this one off. I'll report back to you with my findings. In my early experience I had my chops busted many times by an AHJ about exposed Romex and it just became internalized that it's not permitted. Now I can step back and check the facts. Personally, I will continue to cover up exposed Romex, but I won't feel bound by that as an enforceable rule-- subject to my pending confirmation. I also realize-- and stated in my original post that there are places where the same rules and standards don't apply anyway: (agricultural, various states, countries, etc.). There are many different ways around the world to cut the cheese.

Wayne,
I must assume that you would also object to AC cable, MC cable, Flexible Metal Conduit, Liquidtight Flexible Metal Conduit and Rigid NonMetallic conduit installed in exposed locations. All of these wiring methods say tha you cannot use them where exposed to physical damage.

Re: NEC Poster's!! Can I see what you look like too?

I would look at the circumstances. I guess I was set up by those first few encounters with the AHJ. The were hard nosed. What they said made sense, so I internalized it as true and never questioned it. It's hard to question authority, and doubly hard when what they say makes perfect sense. It's fortunate that I am starting "fresh" and can re-formulate my beliefs with the help of this forum.

I have seen situations where simple armor would not be enough to protect a cable from damage. In those cases rigid pipe, EMT, or even poles cemented in the ground would be required (for example where a fork lift could run into an MC, or where cars might run into EMT).

What is the consensus on running say UF through a trench, daylighting it, and then stapling it to plywood siding on its way to an outdoor light fixture under a well covered eave?

I think I have been fairly careful in qualifying all my remarks. It's a belief, based on an interpretation by an AHJ many years ago.

I wish the electrical code were a more straight-forward read. The terminology is confusing, contradictory, downright wrong (when mis-typed), and intimidating. The whole thing should be rewritten and distilled down to its basic elements. There is way to much room for interpretation regarding protecting Romex, or how many NM's through a hole, etc. It is counter-productive to be able to spin the code so many different ways depending on who's writing the rules, who's implementing the work, and who's enforcing the rules. It's like when one Professor writes an exam and yet another one grades the exam. Whew!

Thanks for playing!

That would be a direct violation of 300.5(D)(1).
