What do you guys use, solid or stranded for #12 or 14 and why. (except romex, isn't that all solid). I use solid 14 and stranded 12. Why, I don't know. Thats what I've always used. I think the stranded 12 is easier to work with. What do you guys think.
Solid wire is easier to push into a pipe. Stranded wire is a little easier to work with. Unless it's XHHW and the insulation is melted into the wire. We have ran into this problem with all the wire we are using on our current job. Someone told me Stranded is a better choice because it has more surface area to carry the "juice" on.

I use #14 solid & #12 stranded for residential. We used to use #12 solid for the same reason eswets uses stranded, because we always did. Then after working with others on commercial work I really began to appriciate stranded.
Stranded is better for pulling and stuffing the device into the box, but worse for terminals on devices (unless they are expensive back wired). #14 solid is so easy to work with, the advantage of flexiblity never seemed to outweigh the ease of terminating.
I do keep a stock of #14 stranded that I use for wiremold in modular sunrooms.

Use of either depends on the application. Flexibility is normaly an issue. The more strands you have the more flexible the wire. Generaly in my experience solid is only used in 12awg or smaller and is specificaly stated in specs to use stranded for anything bigger than 14awg. Stranded will always pull easier in raceway. Solid will obviously push easier in many cases, but not all. Imagine trying to pull or push a solid 500kcmil. Never happen. In industrial environements I have worked in, solid wire isn't even allowed to be used. Agood book (tool) which every sparky should have is theAmerican Electrician's Handbook. It goes into specific detail on almost any question like this you would have. Division 2 Properties and Splicing of Conductors.

The only solid I ever use is in a cable such as NM or MC. I almost always work by myself & I found that I can pull most conduit runs without help. When I used to use solid, I usually damaged the insulation or couldn't make the pull on my own.
Few things are harder to put up with than the annoyance of a good example.

The only place I use solid is NM cable. I use stranded MC. It's only about $7.00 more per 250' roll than solid and is a lot more flexible. I hate the feel of pulling solid conductors through pipe. If you have trouble side wiring stranded on devices, left-hand twist the strands before you bend the hook around the terminal screw. As you tighten the binding screw the strands won't spread.
