If the exterior wall shear panel/sheeting inspection has not been completed, what is the minimum distance all wiring and device boxes must be from the exterior surface of the framing member?

1-1/4 in
2 in
2-1/2 in
3 in

The correct answer is: 2-1/2 in

The correct distance for wiring and device boxes from the exterior surface of the framing member, if the exterior wall shear panel or sheeting inspection has not been completed, is 2-1/2 inches. This requirement is in place to ensure that there is adequate space for inspection and compliance with structural integrity and safety standards. The distance helps prevent any damage to wiring during the installation of the shear panels and allows for potential adjustments or corrections during the inspection process. This regulation is designed with safety in mind, ensuring that the electrical components are not inadvertently compromised by subsequent construction activities or inspections. By maintaining a distance of 2-1/2 inches, electricians can ensure that the wiring remains protected and accessible for future evaluations without risking breaches or interference that could occur if the wiring were installed too close to the edge of the framing members.
