Solid Core vs.. Stranded Electrical Wire

In our smaller circuits,  15-30 amps,  which type of wire do you use:   solid or stranded?  

 

We are going to use EMT conduit and I was just thinking about this.    Thanks.

I thnk it doesn't make too much difference.  Stranded is more flexible.  The skin effect phenomenon doesn't seem to make a huge difference.  Solid may be cheaper.   If you google the topic you'll get some different opinions but I think in general the above is a fair statement.

Re: Solid Core vs.. Stranded Electrical Wire

Use stranded where you need maximum flex, or in the presence of vibration, such as hooking to an elcetric motor.  For general wiring, use solid wire.  In fact, for wiring that connects under a wide screw head, such as a standard recepticle or switch, solid wire is better because there are no loose strands to contend with that can work out from under the screw as you tighten it, and touch something you don't want it to.
