When running EMT in verticle riser what is the furthest distance you can space out the supports. The flooors are 14' and was hoping I could support just on each floor and not in between...

table for verticle pipe runs, but I don't see it.
I hope you got a picture of it!Dexie123 said:If at each floor of this riser on the floors 14' apart the emt is supported with kindorff and is encased in concrete? Can this change the distanced of the support?

cadpoint said:I always go by coupling's, once every ten feet OK, one coupling, once supported good for three feet on each side of the supported coupling, of course this is for horizontal runs.
don_resqcapt19 said:Are you saying that you must have a support within 3' of a coupling? If so I do not agree.
There is no requirement for supporting EMT relative to the position of couplings, or vice versa.cadpoint said:Horizontal, yes. Vertical no, full ten foot sticks.
Ummm... the pdf you linked to is for 20' sticks of EMT, not PVC, and S-RMC.e57 said:...
Not sure bout EMT - but I do know you can get 20' sticks of PVC and RMC special order...
Can you cite the code setion that says this?cadpoint said:Horizontal, yes. Vertical no, full ten foot sticks.
Yeah went back to chuck that in.... Man that google is quick....Smart $ said:Ummm... the pdf you linked to is for 20' sticks of EMT, not PVC, and S-RMC.
Not sure why the OP wants to skimp on support, but don't forget that if the conduit is supported at the floor of every level, i.e. every 14', the intermediate supporting can be anywhere between 4' and 10' AFF and meet code.

It's the way I do it with a horizontal run. Full 10 foot stickssmart$ said:There is no requirement for supporting EMT relative to the position of couplings, or vice versa.
An exception permits extending support within 3 feet to 5 feet of a run termination provided
no couplings are within that 5 feet. The exception uses the term "unbroken" to mean
no couplings.
