Ci.1 This annex applies to tamper-resistant cover plates for 125 volt. 15 and 20 A flush-mounted receptacles.
C. 1.2 These tamper-resistant cover plates are not intended for use in patient care areas of health care facilities
C. 1.3 These requirements do not cover kits or assemblies comprising receptacles and nonmetallic cover plates that cover the receptacle face and where the cover plate cannot be installed on any other receptacle. Such assemblies are specifically evaluated for compliance with all applicable requirements for receptacles and cover plates.
C.2 Definitions
C,2.1 TAMPER-RESISTANT COVER PLATE: A cover plate used with a standard flush-mounted receptacle to provide a level of p-otection against shock for young children who attempt to insert a foreign object, such as a key, into the receptacle opening.
C.3 General
C.3.1 Unless otherwise specified, a tamper-resistant cover plate shall also comply with all the requirements of this standard.
C.4 ConstructIon Requirements
C,4.1 A tamper-resistant cover plate shall not hinder the complete seating of an attachment plug of the type ntended for use with the receptacle.
C.4.2 Area A as defined In Figure C.1 shall be free of any obstructions that would prevent the full seating of an attachment plug on the face of an installed receptacle, Any obstructions outside the defined area shall have a feature that extends 12 mm (-0 mm ÷0.8 mm) from the face of a receptacle to preclude partial engagement of an oversized plug, adaptor, or similar device.
C.4.3 A tamper-resistant cover plate for duplex receptacles or multi-gang installations shall provide independent protection for each receptacle outlet.
C.4.4 A tamper-resistant cover plate shall require a minimum force or multiple motions to unlatch a tamper-resistant feature to gain access to the live receptacle slots for insertion of an attachment plug. The minimum force or multiple mohons shall be determined In accordance with the access test in Clause C.5.2. Insertion of the attachment plug is not considered one of the multiple motions.
C.4.5 A tamper-resistant cover plate shall return to the tamper-resistant condition upon removal of the
attachment plug without requiring any action from the user.
C.5 Test Method for Tamper-Resistant Cover Plates
C.5.1 Probe test
C.5.1.1 Twelve previously untested cover ptates shall be used for this test. When subjected to the probe tests specified in Clauses C.5.1 .2 and C.5.1 .3. the tamper-resistant cover plate shall prevent contact with live receptacle parts.
A tamper-resistant cover plate for a duplex receptacle shall be tested at only one outlet face: sx of the plates shall be tested at one outlet face, the other six at the other outlet face. The cover plates shall be installed as intended on II ush-mounted receptacles using a plywood surface.
C.5.1.2 The probe shown in Figure C.2 shall be applied to each cover plate with a force of 2.2 N (8 ounces) in an attempt to bypass the tamper-resistance mechanism and contact live parts of the receptacle. A suitable indicating device (such as an ohmmeter, battery-and-buzzer combination, or the like) shall be used to determine whether contact is made. The probe shall be manipulated in any onentation that permits access to live parts within the receptacle.
C,5.1.3 The test shall be repeated using the probe shown in Figure C.3 with a force of 45 N (10 pounds). C.5.2 Access test
C.52. 1 Six previously untested cover plates shall be used for this test. The cover plates shall be installed as intended on Ilush-mounted receptacles using a plywood surface. The action necessary to release or unlatch the tamper-resistant feature to gain access to the energized receptacle contacts shall require a minimum of 45 N (10 pounds) force or shall require 2 or more motions. Insertion 01 an attachment plug is not considered one of the multle motions.
C.5.3 Ball-pendulum impact test
C,5.3.1 Six cover plates which were previously subjected to the probe test shall be used. When subjected to the ball-pendulum impact test of Clauses C.5.3.2 to C.5.3.5. a tamper-resistant cover plate shall exhibit no breakage of the plate or tamper-resistance mechanism or any other damage that could increase the risk of lire or electric shock. The plate shall be capable of functioning as intended alter completion of the test.
