Using NM wire...I believe code says any wire coming from a box should be attached/stapled within 9" of the box...is this also required for adding switches/outlets etc...to existing wiring. With the boxes designed for old work...you just have to cut out the box size hole and there you go...the twist screw clips/wings tighen the box to the inside drywall as you turn the screws...but if you must also staple the wire some 5-9 inches away on a stud..then you are making a much bigger drywall repair job also ? Is the wire required to be stapled on minor remolding work near the newly installed box ?
Also...in the outlet boxes available for old work remodeling...they have tabs that bend out for feeding the wire into the box...do most people just bend these tabs back...or can/should you twist them off completely ?
Thanks, TR
