10 GFCI Testers and AFCI Indicators
10.1 A normally open momentary contact switch shall be provided on a GFCI tester. The test button on the switch shall be provided with a barrier to guard against unintentional activation. The test button on the switch of a GFCI tester that employs a power-supply cord shall not be required to have a barrier to guard against unintentional activation.
10.1.1 A normally open contact switch shall be provided on an AFCI indicator. The test button on the switch shall not be required to have a barrier to guard against unintentional activation.
10.2 When an automatic timing circuit is provided in the GFCI tester, the timing circuit shall function to open the circuit in no less than six nor more than 7.2 seconds after the test button is activated. See 22.3.
10.3 A GFCI tester and an AFCI indicator shall be provided with an audible or visible indicator which shall be present until the GFCI or AFCI trips.
11 Retention Testers
11.1 The line blade or blades of a retention testing device shall have a width of 0.240 — 0.260 inch (6.10
— 6.60 mm) and a thickness of 0.055 — 0.058 inch (1.40 — 1.47 mm). There shall not be any holes or
detents along the length of the blades beyond 0.250 inch (6.35 mm) from the point where the blades enter
the body of the tester.
11.2 A retention testing device shall include a means to test the retention force of the grounding contact of a receptacle. The grounding pin of the tester need not be located on the same plane as the line blade or blades. The grounding pin shall have a diameter of 0.184 — 0.190 inch (4.67—4.82 mm) and a rounded tip with a radius of 1/8 inch (3.2 mm).
11.3 A retention tester need not be provided with two line blades.
11.4 A retention tester that incorporates more than a single line blade on the same face of the device shall comply with all of the following:
a) The tester shall indicate the test results of each receptacle contact independently in one single motion (insertion into and removal from a receptacle);
b) The tester shall have plug blades for testing one or more of the following configurations: 2 pole, 3 wire, 15 A 125 V; 2 pole, 3 wire, 20 A 125 V; 2 pole, 3 wire, 15 A 250 V; or 2 pole, 3 wire, 20 A 250 V as described in Wiring Devices — Dimensional Specifications, ANSI/NEMA WD6; and
c) The test results shall not be displayed or otherwise indicated as an average value.
11.5 Each line blade and grounding pin of a retention tester shall be provided with a dedicated means, such as a hole, notch, or the equivalent, intended for the sole purpose of periodically attaching the calibration tool referred to in 11.10. The attachment means shall be located within 0.250 inch (6.35 mm) from the point where the blades enter the body of the tester.
11.6 The line blade or blades and grounding pin of a retention tester shall be sufficiently hard to guard against the effects of wear. If a material other than steel is used it shall be hardened by electroplating, anodizing, diffusion, or any other process suitable for the application. The hardness coating shall have a nominal thickness of 0.0025 inch (0.064 mm) on each side of the blade and on the surface of the grounding pin and shall have a minimum Rockwell C Scale Hardness of 28 or the equivalent.
11.7 A retention tester shall indicate the force exerted on the test blade by the contacts of a receptacle or otherwise indicate whether the contacts under test have the minimum acceptable retention force of 6.25 ounces (1.74 N).
