The Brazilian standards, which content is responsibility of Brazilian Committees (ABNT/CB) and the Organizations of Sectorial Standardization (ABNT/ONS), are elaborated by Study Commissions (CE), composed by representatives of the involved sections, like: producers, consumers and neutral (universities, laboratories and other). The drafts of Brazilian standards, elaborated in the extent of ABNT/CB and ABNT/ONS, are circulated for Public Consultation among ABNT associates and interested parties. This Standard contains the annex A, it is normative. 1 Scope 1.1 This Standard sets the dimensions for plugs and socket-outlets with nominal characteristics up to 20 A/250 V a.c., intended for household and similar purposes, to be used in the connection to distribution systems with nominal tensions rated between 100 V and 250 V a.c. 1.2 This Standard is applied to the plugs and socket-outlets specified in NBR 6147. 1.3 This Standard is not applied to the plugs and socket-outlets designed to the class 0 equipments. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this Standard. The indicated issues were in force when this Standard was published.

For the semi-built-in socket-outlets, the impossibility of single-pole insertion shall be verified. Ï If those dimensions were not respected, a gauge shall be used for verifying the impossibility of single-pole insertion. Regarding the use of shutters as the only way to prevent single-pole insertion, see NBR 6147. Ð This dimension has been provided for the plate, the guide of the plug pins and for the eventual shutter mechanism. The shutters are optional. It is not necessary to supply a proper space to the shutters in those models without this device. Ñ In the limits of that thickness, the guide for the plug pins shall have at least 1,5 mm with the specified diameter. Ò Small chamfer or radius. Ó The points that first touch the alive contacts and the earthing-contact shall be verified. Ô This dimension is verified using a gauge in the most unfavorable conditions. Õ The contacts shall be elastic. Their shape might be different from the tubular. An entrance in an appropriate way, with a chamfer or a radius, is necessary to prevent damage of the contact when the plug is inserted in the most unfavorable angle. Its convenience is verified by performing all the tests specified in NBR 6147. Ö The earthing-terminal shall be identified with the symbol (3.2.19 of NBR 11467:1991). The identification of the other terminals is optional. The marking shall be put close to the terminals. It is not necessary to mark the terminals in those models that cannot by disassembled. Dimensions in millimeters NOTES 1 See explanatory notes on page 12. 2 These figures are not intended to govern the plan, except in the shown dimensions. 3 The plugs can, or cannot, be disassembled.

Engagement face Earthing-pin and optional construction for the pin that carries current (alive) No sharp edges 12 NBR14136:2002 Explanatory notes for figures 7 and 8 Î The earthing-terminal shall be identified with the symbol (3.2.19 of NBR 11467:1991). The identification of the other terminals is optional. The marking shall be made inside the body, close to the terminals. It is not necessary to mark the terminals in those models that cannot be disassembled. Ï The distance between the engagement face and the cord or the exit for the cable or the eventual cord protection shall be of 14 mm, at least. The conformity is verified by measurement. Ð In the limits of this dimension, the outline shall not be smaller than the outline of the engagement face. Ñ In the limits of this dimension, the outline should not be larger than outline of the engagement face. Ò The insulating sleeves of the alive pins are optional. If the insulating sleeves are separated parts, they shall penetrate in the body of the plug in, at least, 3 mm measured from the engagement face. Ó The external diameter of the insulating sleeves shall not overcome the uncovered part of the pins. Ô To avoid the shutters damage, the extremities of the pins shall not present sharp edges or burrs; they shall be rounded, as shown. Õ The angle of 90º sets the maximum area which the flexible cord entrance shall be allowed.

Î A collar shall be provided for the models without protecting surface or a recess, or a combination of a collar and a recess for the socket-outlets with protecting surface. In cases of such combination the impossibility of single-pole insertion shall be verified. Ï If those dimensions were not respected, a gauge shall be used for verifying the impossibility of single-pole insertion.
