Re: Who's good with box fill?

Nice one ,Bob.

Quick estimate 10-12 c.i.=5 #10's

Box in picture I'll say 2 networks(boats) or 8 maybe even 8+grd.=9

You said go high!
 
Re: Who's good with box fill?

I'll venture a guess. I'll say 7 current carrying conductors with one volume allowance for grounds.That's assuming no device.
 
Re: Who's good with box fill?

If the box is not marked with the cu. in. then go to table 314.16 (A) and find the box that best fits. In this case the best fit would allow 5 #10s

My guess as to how many will be "to many" and I base this on your comment to guess high.

How did I do?
:)

Two networks yes, however they are 3 phase 4 wire networks. :p

They where all teriminated in the box so that makes 16 + ground.

But that is far from all! :p
 
Re: Who's good with box fill?

I'm real good at box fill. I can fill up any box to capacity, and then some. Isn't that what they make hammer handles for? :D
 
Re: Who's good with box fill?

Taking the measured dimensions as "inside" and extrapolating for the molded screw standard volumes I get:

Volume before subtracting screw standard volume:

26.56?"

Screw standard volume:

1.4?" each

Total volume: 23??"

9 #10 AWG's.


Edit: So I, not having ever done this

, I should be able to get 14 or 15 maybe even a couple more.

Re: Who's good with box fill?

OK I will just say it, I came up with 27 10 AWG conductors in the box!

It did not have a box cover but it was buried with bark mulch and dirt. It used to have a PAR 38 holder on it but they have all been abandon and buried.

Strangely it blew up, who could have predicted that? :p

There where seven 120 volt circuits and two 277 volt circuits.

There where fourteen 10 AWGs coming in each raceway.

Did I mention it was 10 AWG solid?

There is another issue if you think about it.
 
Re: Who's good with box fill?

Whoever was able to do that deserves the Nobel peace prize for comitment and effort. Right after he changes the box to one that's a little bigger. :D
 
Re: Who's good with box fill?

I was just wondering, were there any 300.14 violations in there or was this pretty much up to code otherwise? :D :D

Well as they EGC came from the 120 volt panel used as a raceway for the 277 circuits I guess 300.3(B) was complied with. :D :D [/b][/quote]Yeah sure if that section was changed to millimeters instead of inches. :D
 
Re: Who's good with box fill?

Bob, string theory needs 11 dimensions and that's supposed to be elegant mathematically. It's understandable that nobody really paid much attention to the fact that relativity's space time fabric (that this theory attaches itself to) is only a mathematical analogy and not an actual construct that actually exists.

You see what I mean? :D
 
Re: Who's good with box fill?

OK I`ll bite (CHOMP) if it`s a 4 sq I stop using extensions after 9 not code,just that is the deepest my screwdriver will go :D
