What is reason that stranded is easier to pull through conduit rather than solid??
Why is it less painful to get hit in the head with a rope than a baseball bat?

#10's are a bear to pull and can easily be damaged. Also, skin effect is another great advantage of using stranded.

As far as skin effect goes, individual stranding does not provide sufficient separation and the conductor is treated as if it were a solid. This is also true for compact and sectored construction as well.
For normal power systems of 60Hz, skin effect is a fairly useless topic to be taught.
I think in general it is simply a 'fun fact' which is almost always used out of context. After all, when skin effect does become an issue so might proximity effect, but we almost never hear of this topic even being taught.I think skin effect should indeed be taught. That way it would be understood why, at 60 Hz, we don't bother with adjusting for skin effect given the size of the conductors we use.
I'll bite: What is proximity effect?
In a nutshell, the closer a group of alternating current carrying conductors are to each other, the greater the effect the magnetism created by one conductor will be on the current in the other conductors.I'll bite: What is proximity effect?
"Get closer, and I'll bite." :grin:I'll bite: What is proximity effect?
Frankly, I don't think I'd even try it.There is no way on earth that 15 solid #10 conductors is as easy to pull in as 15 stranded #10 conductors.
For raceways filled to near capacity stranded is the only way to go. With this new trend towards value engineering we constantly see 1" EMT's spec'd with 15-#10 solid conductors as the norm. There is no way on earth that 15 solid #10 conductors is as easy to pull in as 15 stranded #10 conductors.

on the original question, you might take into effect that you can't use stranded on the standard grade receptacles, I have heard about twisting counterclockwise, but unless you use a better grade you need to go with solid. Although someone may prove me wrong.
