riding against outside of the boxes. 2. Keep outlet boxes free of plaster, drywall joint compound, mortar, cement, concrete, dust, paint, and other material that may contaminate the raceway system, conductors, and
cables.
3. Install device boxes in brick or block walls so that the cover plate does not cross a joint unless the joint is troweled flush with the face of the wall.
4. Install wiring devices after all wall preparation, including painting, is complete. C. Conductors:

2. Keep each wiring device in its package or otherwise protected until it is time to connect
conductors.
3. Do not remove surface protection, such as plastic film and smudge covers, until the last possible moment.
4. Connect devices to branch circuits using pigtails that are not less than 6 inches (152 mm) in length. 5. When there is a choice, use side wiring with binding-head screw terminals. Wrap solid
conductor tightly clockwise, 2/3 to 3/4 of the way around terminal screw. 6. Use a torque screwdriver when a torque is recommended or required by the manufacturer.
7. When conductors larger than No. 12 AWG are installed on 15- or 20-A circuits, splice
No. 12 AWG pigtails for device connections. 8. Tighten unused terminal screws on the device.
9. When mounting into metal boxes, remove the fiber or plastic washers used to hold device
mounting screws in yokes, allowing metal-to-metal contact.
