## max number of bends

Hey guys, I was trying to find the max # of bends in a 100' of EMT. Also isn't there some little degrees variable in thate equation somewhere?

Thanks,

Shaun

360 degrees max. 1' to 1,000,000'

See Article 358.26 of the 2002 NEC for allowed bends in one run of conduit for EMT.

You must count ALL bends. This includes box offsets, saddles, etc... in your 360 max.

## Re: max number of bends

At one point, I was thinking of proposing a Code change to eliminate the inclusion of the box offset [since is is so small and the the wires {40%} actually go straight thru].
But one day I pushed a run of about 40' and it had a super bend and then another 90º and then a 22.5º offset and finally the box offset. I got the wires pushed almost all of the way and investigation showed that it got hung up entering that last box offset. So it does make a little difference.

Luke believe it or not we had a electrician (well he thought he was one) that thought that as long as every bend had a bend in the opposite direction it would cancel the first bend out, so he didn't think it needed to be counted.

Do you know why they decided on 360 degrees of bends? Well it's pretty simple actually, it's because when you have something like a wire or a Horse's Rein,(Yeah just like in the Old Westerns, where they just throw the horses rein over and around the Hitching post) that encounters 360 degrees of friction, it effectively becomes a "CINCH" type Knot. And when you try to overcome that much of resistive friction, you can damage the wire, then you have it to do all over again.
I worked on a job once where the Specs only allowed 180 degrees of bends, with every bend, no matter how slight, was to be considered a 90 degree bend. Therefore before and after every box offset, we had to install a Pulling "C" type Condulet. Regardless of the type or size of conduit.
What the Hay, they pay the money, they get it the way they want it.

## Re: max number of bends

so you have already got your answer, "360 degrees", that is what the answer will be on a test. In practice, as a fellow electrician, when you have on long run with multiple circuits, it is always a good idea to install a pull box.
