Which junction box is better to extend circuit from?
The pull-light one is closer to my intended light install and the other one is a little further. Do these look like they have enough room in them to branch out to extend a circuit? The light junction box also has a doorbell transformer coming out of it.
Why does the circular box have double cables coming out of each side?
pull-light
round junction box

I never knew what the attraction was to using those round boxes as splice boxes.
The 4"square AKA as a 1900 box makes a superior splicing box.
Comes with 12 knockouts around the sides.
Comes in different depths depending on the amount of cables.
The one box with the four cables is basically filled and the other one with the three cables and the transformer is pretty full too.

So what do you recommend I do?
Wait, I think I got it! Can I cut along a length of the wire somewhere and add a junction box and then branch out from there?

The box with 4 cables in it I would just get a new square box big enough to do what you want. Throw old box away.

Ray, why can't I just have 3 wires in one Junction though? I mean, once I cut the wire I have to connect it inside a junction box and then also connect the new POWER OUT (to extend circuit) inside the same box? Wouldn't I have just 3 wires connected under the junction?
Oh wait, I think I got it. If I cut the wire there won't be enough cable left over to make the connections?
Also, How do I respond with quoting you, so that people know who I'm quoting?
Of course, I need a permit also to do even this?

Thanks Ray, but I thought your reasoning for using 2 boxes was because once I make the cut I won't have "6 to 8 inches" left over on each side to connect the main cable back up?
If this is my mother's house can I get a permit to do the work for her?

An easier solution would be to add an extension ring for added volume.

How many wires can safely go in one wirenut though?

Depends on the size of the wire nut and the size of the wire.

Since you'll be doing wiring work.... pickup a box of red and a box of yellow wire nuts so you have both. The blue or blue/gray are nice to have on hand but a box of 100 will be expensive.
2-3 #14's would be yellow.
3-4-5 #14's would be red.
There really is no definitive list. The list is mostly a guide line. Sometimes your splice is a bit larger.... you can use one size up wire nut. As you use them you'll see how they grab and how they cover the insulation.
You don't want to have to use tape to cover the insulation.
And just as an aside to your aluminum wiring thread..... wire nuts are NOT used on aluminum wire.
