Foreword
The purpose of these Standards is to present the dimensional requirements of wiring devices in order to assist the user in selecting and obtaining the proper product for a particular need and to minimize the possibility of unsafe interchangeability between configurations. In the preparation of this Standards Publication, input of users and other interested parties has been sought and evaluated. User input will be formally sought by the canvas procedures of the American National Standards Institute. The Communications Department has worked closely with the Engineering Department and with individual NEMA Subdivisions in the drafting of this manual and acknowledges the need for periodic review and updating. Proposed or recommended revisions should be submitted to: Vice President, Communications Department National Electrical Manufacturers Association 1300 North 17th Street Rosslyn, Virginia 22209
Publication ANSI/NEMA WD 6-2002 revises and supersedes NEMA Standards Publication WD 61997.

Scope
These Standards cover dimensional requirements for plugs and receptacles rated up to 60 Ampere and 600 Volts. They also include dimensions for wall plates. These Standards do not cover performance or other requirements since these are included in NEMA Standards Publication WD 1, General Requirements for Wiring Devices.

Introduction
Throughout this publication the following shall apply: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. All dimensions are in inches, unless otherwise specified. Decimal dimensions without tolerances shall be subject to a plus or minus 0.005inch tolerance. Angular dimensions without tolerances shall be subject to a plus or minus 1 degree tolerance. “G” denotes equipment ground. “W” denotes system ground. Leading edges of plug blades shall be free of burrs and sharp edges. All slots and slot tolerances are symmetrically located about centerlines. Female contacts associated with plug blades that are 0.125 minimum longer than other blades are engaged prior to the other female contacts. Configurations utilized on alternating current systems are limited to 50 or 60 Hertz, unless otherwise specified. Dimensions shown in these standards are for the purpose of interchangeability, and do not preclude other designs. The electrical ratings of the configurations in these standards are AC and DC, unless specifically stated ‘AC’ or ‘DC.
