`Introduction
`
`Throughout this publication the following shall apply:
`
`All dimensions are in inches, unless otherwise specified.
`Decimal dimensions without tolerances shall be subject to a plus or minus 0.005-
`inch 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.
