You are watching: Can you mix solid and stranded wire


I have two circuits that go through a number of junction boxes.Panel to JB#1 to JB#2 to JB#3 to JB#4 to where it needs to go.Normally I try to use same color same type conductors for one circuit. However in this case it is a real pain to feed new conductors all the way through, and I happen to have extra conductors left in the EMT conduits from other circuits I purged.So is it ok to use stranded #12 for first leg, then splice to a solid #12 for second leg, back to stranded #12 for the third leg?Along the same line, is it ok for a given circuit that the hot is a stranded #12 but the neutral is a solid #12?Finally, I see that pig tails are all solid conductors. Any reason one cannot use stranded for a pig tail?

I have to ask why you are switching as you go. Why not use the stranded for the entire job? Buy one spool of enough length instead of two.

Sorry I didn"t explain it clear enough in my original post.This is not new construction so I am dealing with hop skip jump from box to box in the ceiling. The raceways are all EMT conduits with 40 year old solid conductors.There are some existing solid conductors in the conduits that are NOT utilized, they don"t pull out easy probably because they are wrapped/tangled with other conductors inside the same conduits.So the question was do I disconnect, pull out all eight solid conductors out of the 3/4" conduit, just so I can separate out the two solid (one hot one neutral) I don"t need and replace them with same size stranded and pulled them back in, or can I utilize what"s already there.

Never said there was anything wrong with it. Just wondering he was swapping wire type at certain sections of the job.

OK, so some of the conductors are existing and you are adding the stranded. No problem with that. No problem mixing in new work either. Just seemed odd without know about the existing.
