I'm about to rough-in my electrical wiring for a remodel of our bedroom and have seen several videos where people leave an extra 6-8 inches of wire looped outside of an outlet box which will allow for a margin of error when stripping wires or if something happens to the wires when the drywall is put up.

My question is, Is this allowed within US Electrical code for residential wiring?

I think this is a good idea and would like to implement it, but also don't want to be doing something that's dangerous.

enter image description here


If the box has clamps 12" to the staple is allowed if the box doesn't have clamps only 8" is allowed to the staple. I usually try to provide a bit of slack because after years of service, outlet changes because of being worn out, color change or style change the wires become two short if there is a an extra inch or two this saves $ over the life of the home and cost almost nothing.

  • Are you saying 8" from the staple to the end of the wire or 8" from the staple to where the wire enters the box? Feb 17 '17 at 19:01

    8" from the staple to where the wire enters the box

    8" from the staple to the box where it enters unless there are clamps then it can be 12". The sheath needs to be a minimum of 1/4" inside the box or more.
