Briscon staples are U.L. listed.If you read install info ,blue for 14/2,12/2,14/3,12/3.Red staple for multiple stacking.King staples have no listing for how many you can install under each staple.110.3(B) would apply to the Briscon Co. staples.I twww.brisconelectric.com/staplesell the contractors to use the King brand.
 
In the above picture the holes should have been drilled in the middle 3rd of the floor joist.

Remember when drilling holes structural issues apply not just the NEC.

Okay George, I'm sorry I should have said it could possible be bundling. I wasn't specific enough-- shoot me.

It's just that bundling is frequently a foregone conclusion before all the evidence is in, that's all.

I was trying to be funny. :)
 
I would suggest reading the manufacturers installation instructions on the staple packaging. This is always a good idea, when the NEC is short on the information you are looking for.

Ah young grass hopper you assumed we drilled the holes. This one house was moved to its new location. The holes in the joist are from 74 years ago when there was knob and tube put in. The old wires had been pulled out by a demo crew and we reused the existing holes. I agree with you that where you drill out the wood members is very inportant to consider. It is amazing that this many years later none of the joists in the house are cracked.

I know someone who does pretty work. Takes 3 times longer to do the job and I think he is now bunkrupt.
You are doing it pretty for someone to see it 100 years from now! Pretty also means TIGHT, STRECHED - do all agree? How about all those holes drilled too close together? That also is pretty untill a load of snow on the roof etc. breaks the structure. Therefore, pretty is stupid and dangerous a lot of times.

Some amount of effort to be neat pays off in terms of making things easier to understand by installers and inspectors alike. We've gotten kudos for the ease with which our rough inspections are performed.

Being neat can also pay off in how "correct" the work is. I'd never heard of someone having to spend more than an hour or two debugging a house until I started learning about Romex Rangers and the "Two a day or you don't stay" crowd. If that approach works for the business, great.

However, many staples are listed to hold two cables or less, which would make securing three cables under those staples a 110.3(B) violation.

Actually the way I read the box it says 2 CONDUCTORS not cables now GB makes a staple that is a ms150XL that will allow 2/4 CABLES.

Julie that romex ranger thing was actually a local add in the paper a few years back.

WANTED 20 ROMEX RANGERS....... :)
 
Barkerf has part right , it is also up to the AHJ , to prevent a red tag
also check on number of runs per hole .
I've encountered different answers in the same city !

Experimentation (and the discussion of experimentation) probably should happen over yonder. :)

Your link was a little big for me, at 1.4MB. Do you think that's a typo, or do you honestly think you have to buy a different product to staple 14-3? :D
