EBK ELECTRICAL WIRING RESIDENTIAL
When a switch (device) box is nailed to a stud, and the nail runs through the box, the nails must not interfere with the wiring space. To accomplish this, keep the nail:
- a. halfway between the front and rear of the box.
- b. a maximum of ¼ in. (6 mm) from the front edge of the box.
- c. a maximum of ¼ in. (6 mm) from the rear of the box.
Choose the appropriate option that provides the nail’s place to accomplish the given condition.
Discussion:
Consider that the device box or switch box is nailed to a stud. The nails should not interfere with the space utilized for wiring when nail runs in the switch box.
According to NEC 314.23(B)(1), the nails should be kept at a maximum distance of ¼ in., which is 6 mm from the back side of the switch box...
