The National Electrical Manufacturers Association (NEMA) published ANSI/NEMA WD 6-2012 Wiring Devices—Dimensional Specifications. This standard covers dimensional requirements for plugs and receptacles up to 60 Amperes and 600 Volts. Also included is the recommended marking for automatically-controlled receptacles.
WD 6 discusses the plugs, receptacles, and cover plates (i.e., wall plates) used in almost any electrical installation such as residential, commercial, and industrial buildings.
Substantive changes to the current document include:
- The introduction of the marking for automatically-controlled receptacles adopted by NEMA and mandated by the National Electrical Code®
- Dimensions for 2 1/8-inch mounting plates—single and dual
