4.6.3.2 Grounding blade. Using a hardened polished steel pin with a spherical end (see figure 3), the grounding contact shall be conditioned by 20 insertions. After conditioning a 0.184 inch (4.67 mm) diameter pin shall be inserted in the grounding contact and shall be capable of supporting at least 4 ounces for one minute (see figure 4). The forces shall be applied in a direction normal to the face of the receptacle and tending to withdraw the pin.
4.6.4 Terminal strength 15 and 20 ampere, 125 and 250 volt devices only (see 3.6.3).
4.6.4.1 Connector plugs, cable outlets and male inlets. The samples shall be tested with stranded conductors as used in jacketed cords. One half of the samples shall be tested with the maximum size and type wire for which the device is rated and one half of the samples with the minimum size wire for a total of 6 terminals. The wires shall be connected to all of the terminals of each device as in normal use. If binding head screws or any other system which depends upon screws to achieve connections to the
wire is used, they shall be tightened with a torque screwdriver until a torque of 14 inch-pounds is reached. The screws shall be loosened and retorqued 5 times. A pull force of 20 pounds in a straight line shall
then be applied once on each wire for 1 minute unless an integral built-in strain relief is part of the device under test, in which case the pull force shall be 10 pounds. The built-in strain relief must require the device to be fully assembled before the device can be used in its normal manner. The device shall then be examined for conformance to 3.6.3.
4.6.4.2 Receptacles. Devices shall be tested with solid copper branch circuit conductors, using a minimum of one terminal on each sample for a total of 8 terminals tested. Each tested terminal screw shall be used only once. The minimum (#14 AWG) and maximum (#10 AWG) conductor size shall each be tested with 4 terminals. Side wired devices with back wiring for only one wire per terminal screw shall be tested with 1/2 of the terminals side wired and 1/2 back wired. Side wire devices with back wiring for one or two wires clamped under the same pressure plate and secured by the action of a single terminal screw shall be tested with 1/4 of the terminals side wired and 3/4 back wired. These back wired terminals shall be tested with 1 wire in one retaining means, 1 wire in the other means, and one wire in each retaining means at the same time using each terminal for only one method. Each terminal screw shall be tightened with a torque screwdriver until a torque of 14 inch-pounds is reached. Each screw shall be loosened and retorqued 5 times using a new stripped conductor each time. A pull force of 20 pounds in a straight line shall then be applied once for 1 minute on each wire connected to a back wiring terminal.
The devices shall then be examined to determine conformance with 3.6.3.
4.6.5 Current overload (receptacles and cable outlets only) (see 3.6.4). Mating connectors (see 3.1) shall be coupled and wired as for actual service with suitable conductors. Devices shall be tested in accordance with UL 498 and its applicable bulletins, except that the number of cycles shall be 250 and
the current 200 ± 5 percent of the rated current. At the completion of the last cycle, the connectors shall be examined in accordance with 3.6.4. Test current shall be ac with a .70 to .80 power factor except for devices specifically rated for dc.
4.6.6 Temperature rise (receptacles and cable outlets only) (see 3.6.5). Receptacles and cable outlets shall be tested in accordance with UL 498 and its applicable bulletins, except that the test current shall be
20 amperes for al 15 and 20 ampere devices and the test plug shall have solid brass blades.
4.6.7 Dielectric withstanding voltage (see 3.6.6). An alternating current root mean square voltage of commercial-line-frequency equal to 1,000 volts plus twice the rated voltage, shall be applied between mutually insulated terminals. The test voltage shall be increased from zero at a rate not to exceed 500 volts per second until the specified potential is reached and shall be maintained at the value for one minute. The test voltage may be applied instantaneously for production test at the option of the manufacturer. The connector shall be examined to determine conformance to 3.6.6.
