It is not in the code. You are limited to 360 degree of bends. It may be wise to add boxes, etc for convience of pull and to not overstress wires on long pulls.

just dont have conduit runs longer than your fishtape, unless you plan on sucking or blowing a string in.

Call me green, but I have never seen anyone blow string. Keep in mind I almost always pull in with existings, but I have never seen it blown:roll:
 
another method of blowing in a string is to use a one shot mouse, it is a coil of string that has a small sponge on the end of it the diam of the pipe you are blowing through, you can blow it through with a normal air compressor, it unwinds the string as it is blown through the conduit. my favorite method is t just use a shop-vac and a piece of plastic bag and just suck it through. I keep a small shop vac in the truck, and plastic bags are always laying around.

The bags always seem to work when a mouse will not. :cool:

It's been a while since I have had to buy any new foam mice. I got a packet of 1/2" one's the other day, and I was surprised to see they were about 50 bucks for the pack!

And the plastic bag they came in "free".
 
One time I didn't have anyy mice or a bag on the van and used my shirt. It worked just fine. At least I did remember the shop vac. :D
