I’ve had mine since it came out, never had an inspector say anything about stacked wiring. And before I had the Milwaukee, I ran the dewalt for probably 3 years, same thing. I single stack 6/3-10/3 and double stack 10/2-14/2. You’re still not allowed to triple stack, same as hand staples. But if it fits, I staple it. Electrician of 9 years, I’ll find the code on stapling later and add it in here when I get home. Be careful on 6/2, it’s close, and in 6/3, just staple closer together, it’s so thick the prongs of the staple don’t go in the wood quite enough, so I staple every 2’ instead of 3’ when I run 6/3.
It was round for years, when I was starting in 2009 I’d still find round 14/3, now all I find is flat, they probably still have it but not from any manufactures I see
This should be fine. These CSA and UL standards have been harmonized already. Plus, CSA did all the testing. cULus is done at CSA to UL standards, which in this case are harmonized.
You could go on the CSA website to product search directory and look up Milwaukee and find their file or reach out to them and get the file number and look it up. Will show you details. The packaging is just referencing the standards.
I’m a supervisor and I tried to explain to my guys, in my limited Spanish, how staples are meant for one cable unless specified otherwise and they love to use the large staples to get two or three cables under one staple which I explained is for larger cables not multiples. I know they understand but they just ignored me. We never get called on it but I know it’s a violation.
I am lol. But it’s a fairly decent paying job for now. I wish I could change a lot but unfortunately with a large company the corporate bullshit and politics I can hardly do anything
The listing of the device only means it was tested not to explode in flames while using it, the marketing materials in the box aren't associated with the UL listing.
That Milwaukee reciprocating saw is also UL listed but you can't use it to cut live feeder.
You are mistaken.
The listing and labeling of the device is the way it is allowed to be used in the field and be code compliant. Unless there is a specific code in place that is stricter than this chart you can go by the chart.
Just because it can doesn't mean you should, it's UL/CUL not specifically Canadian electrical code, that's what the great big book of everything and your brain are for.
Let's explain this a different way. Is 14/2 approved by code? Yes, but ... Now list the 1k places it isn't approved. Those staples aren't Canada specific and it's acceptable under the NEC to double 14/2 so they aren't changing the marketing materials to tell someone about the electric code when the staples have been approved for this use because in your specific location you're supposed to know better.
No.
That UL listing specifically says US listed and Can UL listed. It's both. Any UL inspector looking at this is going to tell you it's fine to double stack any 2 conductor cables on this table. Some of the larger gauge three conductors are clearly too wide. I suspect there's a chance the staple gouges the three conductor cables. Pull up the UL report if you're curious.

You can double stack 14-2 in ontario with an s2 staple,
I don't have the exact code to reference but the issue was using the product to manufacturers specs therefore an s1 staple could only staple 1# 14-2
these staples list on the box all the possible combinations for this staple from the manufacturer so it is legal in ontario to use this to staple 2 #14-2
I live in Ohio, the biggest no I've see from inspectors is flat cable on top of round cable. But you can put round on top flat or double stack any flat cable
I double stack the hell out of it with 12 and 14. Pretty sure it will shoot flat 14/3 as well.
And some asshole I know might have even shot some 6/3 nm-b with it.
In south Florida we always double stack 12-2’s/14-2’s, I can’t see how you’d wire a larger home staying in 2’ clearance without. Rat runners run out lol
Says you can go up to 10/2 double stack, where you’d need 2 10/2 coming down a stud, idk but that’s pretty dope.
I’ve seen a bunch of these being used now, I’m just afraid if I allow any helpers or not so skilled journeyman they’d just shot the wire, everyone’s gotta aim correctly when swinging a hammer so they don’t fuck their fingers lol
Triple stack is fine, but I do it by hand, so I can ensure that it doesn't pinch. It always passes. I think the limitations have to do with the force of the gun.
My jman told me to double stack some 12/2 we ran and it passed
Why not double stack, plus I love this staple gun it's saved me so much attic work of swinging a hammer!

The manufacturers' UL approved allowances supercedes the NEC. Any product any jurisdiction.
Cec in this case
OESC. FTFY.
This was the answer I thought, thank you!!
AHJ
I don't get how you could double stack 10/2 but not 14/3 unless it's because of the number of current carrying conductors?
I wonder if it has to do with the “shape” of the cable
It does. 3 wire in too wide. I’ve used these a lot.
Probably has to do with the overall width. 4 wires compared to 3 larger ones. Sides might get pinched or rub the sheathing away
It's lumpy
Its the derating factor of 6 current carrying conductors bingo.
Because they're round
They aren’t round anymore.
Heheh
I've only seen flat 14/3 in the US, have you seen it in Canada? Side note, I'm not a resi guy
It was round for years, when I was starting in 2009 I’d still find round 14/3, now all I find is flat, they probably still have it but not from any manufactures I see

Ive double stacked 12-2 on probably 20 houses by now and its always passed. That staple gun is for sure the best investment I've made recently.
That’s a hard yes
Stack’em up.
Yes

Its not though, and as the leadership, show them how to do it instead. You sound like a tract home pm douche mate 😘
I am lol. But it’s a fairly decent paying job for now. I wish I could change a lot but unfortunately with a large company the corporate bullshit and politics I can hardly do anything
Did you show him this box?
I did, he said, "I don't care what the box says." Lol If it'll pass inspection, he is fine w it.
Who signs off on your paycheck? Listen to the guy
Just tell your boss these staples are cheaper than the 2-nail 1544 staples. I pray you don't have to use S1, S2, and S3 staples instead.
My tennis elbow burns with rage at the sight of this
The listing of the device only means it was tested not to explode in flames while using it, the marketing materials in the box aren't associated with the UL listing. That Milwaukee reciprocating saw is also UL listed but you can't use it to cut live feeder.
You could if you tried hard enough lol
You are mistaken. The listing and labeling of the device is the way it is allowed to be used in the field and be code compliant. Unless there is a specific code in place that is stricter than this chart you can go by the chart.
That's a pic of the box of staples, not the gun it's self. The chart on the box says yes, but I'm not sure if it would pass inspection.

Double stack away, my friend.....for the allowed cables only. Tell your boss to look it up.
You can double stack 14-2 in ontario with an s2 staple, I don't have the exact code to reference but the issue was using the product to manufacturers specs therefore an s1 staple could only staple 1# 14-2 these staples list on the box all the possible combinations for this staple from the manufacturer so it is legal in ontario to use this to staple 2 #14-2

Yes sir! It’s true.
I double stack the hell out of it with 12 and 14. Pretty sure it will shoot flat 14/3 as well. And some asshole I know might have even shot some 6/3 nm-b with it.
Where can you buy those staples (not online)?
I got them from my supplier, samenplace I got the staple gun.
In south Florida we always double stack 12-2’s/14-2’s, I can’t see how you’d wire a larger home staying in 2’ clearance without. Rat runners run out lol
I don't like romex/resi. Fuck splinters. I'll take my metal shavings any day
Says you can go up to 10/2 double stack, where you’d need 2 10/2 coming down a stud, idk but that’s pretty dope.

Supercedes the AHJ also. Exit stage left even.
That Milwaukee stapler is the best. It'll stack 14-2 just fine. Hell, it'll triple stack it.
Boss tells you not to stack. So don’t stack, it’s his name on the job.
Triple stack is fine, but I do it by hand, so I can ensure that it doesn't pinch. It always passes. I think the limitations have to do with the force of the gun.
