how do you count the number of wires you can put in a box.
I know connectors, recepticals and wire nuts count but how much.

Thanks for the help

Have you read 314.16?
 
I am not sure what you disagree about, George. 314.16 seems pretty clear how and what to count for calculation.

What is it that you disagree with?
 
Details smetails...

Take your hammer... the insulated handle part. Hold a device up to the butt end and mark the depth of the device with a permanent marker.

Now anytime you use your hammer to smash the conductors into the box, keeping the depth at least to your mark, you will always have enough room in your box. :wink:

No, it's clear that we look at 314.16. :lol:
 
NO NO NO you have to read the NEC with a mirror and look for 61.413 :wink: Also you dont use your hammer at all costs use that chippy thing that drives ground rods and pack those stupid wires in real good. :twisted:
 
You guys are all wrong. Read my lips:





Wait, that won't work? Okay, read my typing:



Three fourteen, point sixteen.

I prefer binary, but I'm a bit weird that way.

They don't count very much, and are thus very slow at it. You're better off just doing it yourself.

:D
 
See it is just like in Pierres post about ground rods being listed.

You guys are just posting your own opinions. :p
Well IMO it is 314.16.. Well, actually in this one instance, this is pretty close to the absolute truth . :D

If you take a piece of 2x4, and place the end into the box, then hit the other end with the hammer, the wires are compacted better. Where do you think compact conductors come from??

If you check 314.16 it will have the answer you seek.

If that doesn't help, you must not have a code book. NFPA has the NEC online that you can view for free. (Its not very handy, but it will answer your question.) Also, a lot of libraries have the NEC.

You guys are evil. It's the person's first post.

Manch, now that (as I am sure) you read the code book, did you get the answer you were looking for? Do you understand how to do what you are trying to do?
