Finally.

314.40(D).

(D) Enclosure Edges.. All sharp edges of metal pull and junction boxes over 1650 cm3 (100 in.3) in size that are subject to hand contact during customary installation activity shall, at the time of manufacture, be protected or shall be de-burred and rounded to minimize the risk of injury.

I have more trouble with the edges from small boxes like 4 squares and even the plaster rings, but it's a start!

Start of what? Letting OSHA write the NEC? If the subject was to protect the installed conductors from damage due to cuts from sharp edges I would be all for its inclusion, but it is instead a do-gooder intrusion of the type that sank California.
I wear gloves to protect my hands from sharp edges.

Well Macmikeman i could not agree more !

Our company tapes the edges on panels but never heard of a box being a issue and we must ware safety glasses all day hard hats and gloves all day and safety vest whats next ?


Its all about people who have nothing better to do all day but sit in a office and think there saving the electrical trade .

And have never did real electrical work in there lives!

Sorry just a thought . Safety glasses fog up all day in florida ! gloves you cant work with them on! And a safety vest in the building is totally wrong its a hazard waiting to happen it catches on everything but they say its for safety so we will not get hit by a truck inside the building !

I hate that crap! I simply take my safety glasses off if not needed and watch for the safety man:grin:
 
Well now the cost will go up for something we dont really need as i for one have never seen one cut there hands on a 4 square box yet . Panels yes big pull box yes P- ring on a 4 square never .

They should make p rings with smooth edges that would make since for the wire .

The whole purpose of the Code is to protect us and our property.

I don't like cuts on my hands, and gloves don't protect the wires. This is win-win.

I don't see the big deal as it makes our lives easier with no extra work.:-?

It will take up extra space in the codebook, use more ink needlessly, raise the cost of the device to produce it, set a new standard for additional useless feelgoody codes to get written, and the end result will definitely become more extra work.

Have we really needed any of the changes in the past few cycles?

Do we really need to install copper feeders to panelboards?

Do we have to use SqD I-Line panelboards, or will a CH suffice?

Bottom line is, I don't really care either way.

The cost will be passed on to the customer and that means more money for us.
 
Well thats great you dont care thats the trouble with america today money lets start to use what we have before we dont have . keep this going i want to get to 1000 posts
 
Absolutely absurd. Nothing wrong with a little blood letting. Out with the old, I'll make some new.
 
I know I said 'I don't care'

I just personally like the rule.

I do think that if you're not bleeding, you're not working:grin:

Now, the '08 rule with MWBC's is completely absurd.

Will deburred cabinets make installation any quicker? NO

Will I still treat all metal edges as if they are sharp? YES

Will the electrical industry carry on, regardless? YES

I am just trying to get to 700 posts:grin:

Ohmhead, you and Chris Kennedy are my two favorite people on this forum and I love you guys' opinions so keep it up!

PS I was in pensacola last week and went to the NAVY air museum and got to watch the shuttle take off at the IMAX I thought of you and the pics you recently posted from there.
 
I am starting to think it is silly now as I look at the tin-knockers shop drawings for a job I am working on.

I guess they aren't crying about sharp edges so neither should we:)

Well we have over the years many workers records of accidents one major one is cuts every week someone is cut now we also keep records to go back and look at yearly.

Each time theres a report made most are not from 4 square boxes but other kinds of accidents like metal studs 80 % and panel cans and just plain old hack saw or drill bit or hammer cuts or cuts from EMT lots of them yearly . So we ware gloves kevlar type with out fingers so we can work they are totally useless but we are told to ware these 100 % all day .

You see the insurance company thinks this is saving us from cuts yearly but what its really doing is the guy cant work fast so hes not going to get hurt .
 
In my opinion, this rule along with a number of others is outside the scope of the NEC. The scope of the NEC does not permit rules that govern product design and manufacture. These things should be left to the product standards and not placed in the NEC.
90.2 Scope.
(A) Covered. This Code covers the installation of electrical conductors, equipment, and raceways; signaling and communications conductors, equipment, and raceways; and optical fiber cables and raceways for the following: ...

But its purpose is, among other things, the practical safeguarding of persons from the hazards arising from the use of electricity. If I am likely receive cuts so that one can use electricity, my safety has not been guarded.

I am also glad to find clear working space when examining energized parts.

It might be a couple small cuts a year from sharp edges on boxes, I gripe every time that there ought to be a law. Maybe soon there will be :grin:.
