When would you use running threads instead of a length of threaded rigid metal conduit.

Re: Running Threads
svaurez,
can you explain this farther??
Are you talking about a threaded nipple??
I've never seen 1 1/2" hollow all-thread.

Re: Running Threads
The reason running threads are used (and usually against the NEC) is when you can't screw the conduits together. You thread one pipe a little longer, screw a coupling ALL the way on, fit the pipes together and finally unscrew the coupling onto the other pipe.
Normally this is where you use an Erikson or union to connect the pipes.

Re: Running Threads
This method "The reason running threads are used (and usually against the NEC) is when you can't screw the conduits together. You thread one pipe a little longer, screw a coupling ALL the way on, fit the pipes together and finally unscrew the coupling onto the other pipe." is a violation of Section 344.42 (B) Running Threads shall not be used on conduit for connection at couplings.
Running thread can be used between two cabinets or boxes. I sometimes use it when I am in a bind.
