Stranded wire in Industrial against code

[Eddy Current]

Is using stranded wire in Industrial work against code or just a standard? I know people use stranded and solid in Commercial work but almost never vice verse in Industrial its almost always stranded.

 

[iwire]

The NEC allows either stranded or solid and all 15,20 & 30 amp devices are listed for both stranded and solid.

 

[sameguy]

We use it all the time.

 

[guschash]

That's all we ever used.

I know where there is some solid 14AWG in a steel mill in East Chicago, Indiana.

We always want to use stranded but it seems that lately engineers are specifying only solid. IMO #10 solid should not be permitted in a circular raceway.

I read you loud and clear. I'm adding a new paragraph to our standard specs:

"All raceways shall be rectangular."

It works good for tying down ladders

Legal per NEC.

I wouldn't have a problem with #10 solid in a trough. :roll:

should we also ban 500 mcm in circular raceway?

I go out of my way to use stranded whenever possible.
When I engineer a job I specify no solid conductors
My supply house stocks lots of stranded MC now since I usually specify it.
I like to use 10/2 MC stranded for water heaters.

nevermind the raceway. it's not permitted on my truck.

only if it's solid.

Pulling stranded is so much easier. I haven't done a ton of industrial but a couple years worth. I never worked with any solid in the industrial setting. Lots and lots of stranded and TC cable

The only solid I've used in industrial was 4/0 for grounding grid and from grid to above slab metal (skids, motors, and such). Solid can be bent to follow contours and hold its shape.

I actually like solid.

For a short time the supply houses around here started stocking stranded MC, it did not go over well up here. It is now back to solid.

Trying to run stranded MC is like trying to push a car with a rope.

So are you saying that I should have used the rope to pull the car?!?!? Now I know why I've had such a hard time. :blink:

I have never seen solid wire that big. In fact can you even call it wire? Or do you just call it bar or round stock?
