17、ce with the National Electrical Code (NEC), ANSI/NFPA-70. 1.2 These congurations do not cover devices rated at more than 200 A or for more than 600 V. 1.3 This standard does not cover devices having NEMA congurations in accordance with Wiring Devices Dimensional Specications, ANSI/NEMA WD6. 2 Genera

18、l 2.1 The information given in (a) (h) applies to each conguration in Sections C1 C3. a) All dimensions are in inches. b) Decimal dimensions without tolerances shall be subject to a 0.005 inch tolerance. c) Angular dimensions without tolerances shall be subject to a 1/2 degree tolerance. d) Where tw

19、o values are given for the same dimension, the larger is the maximum value and the smaller the minimum value. e) Leading edges of plug blades shall be free of burrs and sharp edges. f) A contour, face dimension, yoke construction, or mounting ears and dimensions for any receptacle construction that

20、is shown depicts an acceptable construction; other constructions may also be acceptable if tested and found to be equivalent. g) A relationship of contact nibs, recess of contacts, or internal construction in a receptacle that is shown depicts an acceptable construction; other constructions may also

21、 be acceptable if tested and found to be equivalent. h) Terminal Identication shall comply with the following: 1) The grounded terminal shall be identied in the Figures by the letter W . 2) The grounding terminal shall be identied in the Figures by the letter G . 3) Other conductors need not be iden

22、tied, but if they are, the letters X , Y , and Z shall be used for identication according to the following convention: i) Viewing the blade end of the plug and proceeding counter-clockwise, starting from the grounding blade (G), or in the absence of a grounding blade, the grounded blade (W), the ter
