THHN / Stranded wire through conduit. Solid will make any change in direction a real bitch.

I use solid in conduit, but its not mandatory.

Quote HistoryQuoted: THHN / Stranded wire through conduit. Solid will make any change in direction a real bitch. Yep, that is the only reason I can think of. Conduit is installed then the wire is taped to a fish wire and pulled through. Little gage wire like 14 wouldn’t be too bad but 10 would suck badly if you had too many bends. I forgot the limit on degrees of bend you can pull through, 360 total I think. |

Depends on how many bends.

Quote HistoryQuoted: Depends on how many bends. This^ Solid is fine with only a few bends, especially in smaller sizes like 12 & 14. I pushed a 40 foot run of solid 14 around two 90-degree bends for a mini split super easy, no fish tape needed. |

Doesn't code require stranded if you are running the line in conduit?

Depends on, size of conduit, length of run , numbers of bends and number of conductors being installed. 3 conductors in a 40 ft run with just a couple 90s isn't bad. Of course stranded is always easier to pull.

Solid will make any change in direction a real bitch. Let he who has not pulled solid wire cast the first fish tape. Solid wire is the suck in conduit. Depends on how long and how many bends you have to seal with. Do not forget that there is a strict limits on 'degrees of bend" in conduit systems. #12 solid is still small enough to work in most applications. It is also usually more expensive than solid. Not sop much in the larger sizes that are almost always stranded. Keep in mind that stranded also requires different terminations than just sticking it under a screw head. |

Quote HistoryQuoted: Depends on how long and how many bends you have to seal with. Do not forget that there is a strict limits on 'degrees of bend" in conduit systems. Just to clarify this, that is degrees of bend between pull boxes or termination points. Quoted: I pull it one section at a time and glue as I go. (PVC) FWIW, I think it's against code to glue PVC conduit with conductors in-place. The primer/glue can dissolve or alter the insulation on the conductors. |

If the run doesn't have many bends I'll go with solid. If there's a lot of bends I go with stranded. Makes no difference to me personally, but I'm not a sparky doing this for a living. I do like that with solid I can sometimes tape everything together and push the entire length rather than bust out the fish tape or pull rope & shop vac (best trick ever IMO). I really don't like fish tapes

Not an electrician, but I'd run solid. I'd rather splice solid than straided.

If you were pulling wire with the bull rope you may have eroded a groove in your conduit at the bends. Mule tape for this prpose |

Mule tape for this prpose Maybe a regional lingo thing but I think mule tape is called bull rope here?!? Flat white woven strap material about 1/16" thick by 5/8" wide, lubricated with something slippery. I have miles of the stuff. The ISP than ran fiber optics through my parent's rural neighborhood was installing conduit that had it pre-loaded in the conduit and they just left piles of the stuff laying in the ditches all over when they were done and had left the job. Probably 40 miles of it if I had to guess. I have a couple miles I rolled up on a spool. |

For that short of a run with just number 12 I would go with whatever is the cheapest. Solid or stranded has the same amp rating.
The code limit for degrees of bend is 360 between pull points. |

Quote HistoryQuoted:Carries more current. More Durable. Can make a direct mechanical connection. The 2nd and 3rd are correct. The first is a common misconception. Electrons only travel on the outside of a strand of wire. A single strand 14 gauge has less capacity than a multi-strand wire because the multi-strand wire has many times more surface area. Choosing Single or Multi-Stranded Wiring - Wire Manufacturers https://www.meridiancableassemblies.com/2017/06/multi-stranded-wiring-assembly Jun 23, 2017 · The increased surface area of multi-stranded conductors decreases the amount of resistance that currents or signal passing through the wire will encounter. Multi-stranded wiring can create challenges when soldering connectors or terminals as it can be difficult to ensure that all of the small strands have been soldered properly. |
