The means of junction and pull box identification shall be as follows:
1.Boxes 8” Square or Smaller – Concealed (Above Accessible Ceilings).
Color identified utilizing fully painted covers. If box contains power wiring, the box shall be further identified with circuit numbers and source panel designation, using machine-generated adhesive label or neatly hand-written permanent marker.
2.Boxes 8” Square or Smaller – Exposed.
Color identified utilizing fully painted covers. If box contains power wiring, the box shall be further identified with circuit numbers and source panel designation, using machine-generated adhesive label or engraved nameplate.
3.Boxes Larger than 8” Square – Concealed (Above Accessible Ceilings).
Color identified utilizing 4” x 4” minimum-sized painted patch, or color-correct machine-generated adhesive label. If box contains power wiring, the box shall be further identified with circuit numbers and source panel designation using machine-generated adhesive label or neatly hand-written permanent marker. Letter height shall be ½” minimum.
4. Boxes Larger than 8” Square – Exposed.

WIRING DEVICE IDENTIFICATION
Wall switches, receptacles, occupancy sensors, photocells, poke-through fittings, access floor boxes, and time clocks shall be identified with circuit numbers and panelboard source (ex. Panel ABC-3). In exposed areas, identifications should be made inside of device covers, unless directed otherwise. Use machine-generated adhesive labels, or neatly hand-written permanent marker.
