It will say right on the package how many and what combinations. __________________ Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.

Scuba_Dave Xtreme DIY'r   Join Date: Jan 2009 Location: South of Boston, MA Posts: 17,248	Multiple wires under one staple Found this one a site No more then two 14/2 NMD or 12/2 cables under an S2 staple. Single 14/2 or 12/2 cables, use S1 staples Single 14/3 12/3 10/3 cables, use S2 staples Of course my boxes do not say S1 or S2 And: Quote: I am preparing for a building inspection for electrical additions to kitchen circuits. I would like to know if two 14/2 NM cables can be fastened under a single staple Generally yes, but it isn't really a code issue but a listing issue. Code says you have to use stuff within its listing. It is up to you to prove the listing for that usage if the inspector balks. Carefully read the box to see if it says anything about doing or not doing multiple cables under one staple
