That is what started this conduit discussion with me. I had an Electrical Inspector wite up a violation last week on a 3\4" EMT bend that was a little over 90 degrees. The EMT was not damaged in any way, so I didn't understand this violation. Of coarse, he didn't write the violation code number, because there isn't one.
The inspector is wrong on this one. I would definately ask for a code reference on this one. The code says that 'there shall not be more than the
equivalant of four 1/4 bends (360 degrees total) between pull points.' I read nothing about one bend greater than 90 degrees anywhere in 358.26. It doesn't even mention 90 degrees. Challenge him on it.

...They also have required a strap within 3' of every coupling. They feel that a coupling is the termination of the conduit.
WOW...now there's another new one on me. I guess they failed to read the 10' strap rule. By their definition, it would negate any need for a strap every 10' if I put one on both ends of a 10' stick of pipe. Talk about alot of extra time and material. Seeing how 358.30(A) goes on to include such items as an outlet box, j-box, device box, condulet and cabinet, it's easy to see the code is talking about where the conduit terminates, not couples together, for strapping purposes when you figure in the 10' rule
and the above examples of terminations. Some guys need to go back to Logic 101. :roll:
