What distance must wiring be from the front of a stud to require protection?

Wiring must be installed a minimum of 1¼ inches from the front of a stud to require protection. This requirement is specified in the National Electrical Code (NEC) to prevent nails or screws from penetrating the wires during construction or renovation activities. If the wiring is installed closer than this specified distance, it may not be protected from potential damage, increasing the risk of electrical failures or hazards.

Using a spacing of 1¼ inches creates a safety buffer that helps ensure the integrity of the wiring installation and minimizes the chances of accidental puncture by fasteners used to attach drywall or other materials to the studs. This regulation emphasizes the importance of protective measures in electrical installations to enhance safety and compliance with electrical codes.
