Securing NM running through joists in unfinished garage

I'm putting in a sub-panel and running 6/3 NM through the joists to the panel location on the opposite side of the garage. The garage/basement is ground level and unfinished.

I'm curious to know if there is a limit the the length of the run? It looks like it will be approx 50' perpendicular to the joist, then will run 5-ish feet on both ends along each joist.

Additionally, other than staples on the parallel joist runs, is there a way I should be securing the NM when it's going through the joists? Or does the parallel run with staples on each end do the job?

Thanks.

 

Staples are the preffered method of supporting/ securing cables, but any fitting that is listed for the purpose is fine. Cable that is pulled through holes drilled in framing members (studs/joists) are considered supported so no additional support is needed. When run parallel to the joists NM cable is required to be supported/secured every 4 1/2' minimum. There is no limit of length of run, unless it creates too much voltage drop which yours is no where near of having.

 

Perfect. Thanks for the info.
