Run one solid conductor in a 3 phase circuit with 2 conductors stranded?

[azebra]

480volt, 100' total length, less than 10 Amp draw, parts shuttle. Supply house sent one solid spool, 2 stranded spools, no big whoop on difference in performance?

Perfectly fine.

Pulling solid conductors through conduit 100ft is not going to be something I would want to do unless that run was dead straight...

In the southeast it was a common spec for all conductors 10 and smaller to be solid, pulling was not a big problem.

Based on the voltage, current, and length, I expect that this run is in 12 or 14 AWG, and not a problem for the pull even if solid.

Not concerned about the pull, little concerned with the difference in performance: ie resistance difference between solid and stranded..

Supply house is over a hour round trip away, didn't want to have to add that to the cost of this service call!!

Gotta check every item ya get these days before ya leave the supply house...

It will not matter at your load and distance.

No significant difference in resistance. There might be a slight difference which would result in slight voltage imbalance, but I'd bet it was in the noise. You might see a 2% difference on your voltage drop (eg. 1% on one wire, 0.98% on the other), which you wouldn't be able to notice given the background of other imbalance sources.

If these were _parallel_ conductors then it would be a problem, because slight differences in resistance can result in large uneven current distributions. But we are not talking parallel conductors here.
