Electrical Wiring in the Home/running 10/3 and 8/3 romex

Advertisement


Question
QUESTION: Hello. According to nec code, can I run both 10/3 and 8/3 romex plus ground wire, perpendicular to unfinished basement ceiling joists (1st floor ,floor joist) using staples? This is non conduit run. Wires would run attached to edge lip of joists, again perpendicular to them.  I am running wires from generator transfer switch from one side of basement to the other, going shortest cable distance. Thanks

ANSWER: Ken
Yes you are allowed to run romex wire side by side on the rafters,joists.This is a normal practise in residential homes.

QUESTION: Ben, so per NEC code, the romex does not have to run through holes drilled in the ceiling joists? you can run a perpendicular run, using staples along lower edge to secure?

Answer
Ken

Yes the NEC allows Romex to be run under the joists,the reason some electricians drill holes is they are not sure the owner is going to finish the ceiling with drywall. Now if all other trades have their equipment hidden in between the joists (which is Hard for HVAC & Plumbers) then you can do the same.

In exposed work, except as provided in 300.11(A), cable shall be installed as specified in 334.15(A) through (C).
- - - - (C) In Unfinished Basements and Crawl Spaces. Where cable is run at angles with joists in unfinished basements and crawl spaces, it shall be permissible to secure cables not smaller than two 6 AWG or three 8 AWG conductors directly to the lower edges of the joists. Smaller cables shall be run either through bored holes in joists or on running boards.
