W-C-596 Connector, Electrical, Power, General Specification ForThis specification covers electrical plugs, receptacles, and cable outlets for service from 120 to 600 volts with current ratings up to 60 amperes and a frequency rating of 50/60 hertz. It does not cover devices for use in hazardous locations as defined in the National Electrical Code. Special plugs, receptacles, and cable connectors for 400 Hz and dc applications are also included. Connectors are to be used with copper or copperclad aluminum wire only.

4.6.14 Assembly security (15 and 20 ampere duplex 125 volt, 50/60 hertz straight blade receptacles only) (see 3.6.13).

4.6.14.1 Test I. With the sample mounted in the fixture shown on figure 6, the test of the security of the assembly shall consist of a force of 100 pounds minimum applied as shown on figure 7, by means of the push out tool described by figure 8, inserted into the slots of the receptacles. The receptacle shall be visually examined for damage as specified in 3.6.13.1. Other test fixtures may be used for receptacles not compatible with the fixture on figure 6, provided they allow for equivalent testing and meet all test requirements specified herein.

4.6.14.2 Test II. With the sample mounted in the fixture shown on figure 6, the test of the security of the assembly shall consist of a force of 50 pounds minimum applied to the bridge shown on figure 10, applied as shown on figure 9. When the force is removed, there shall be no evidence of damage as specified in

3.6.13.2 or yoke deformation exceeding .06 inch (1.52 mm) when measured as shown on figure 9. Other test fixtures may be used for receptacles not compatible with the fixture on figure 6, provided they allow for equivalent testing and meet all test requirements specified herein.

4.6.15 UL 498 tests (see 3.6.14). Connectors shall be tested in accordance with UL 498 for the following requirements:

a. Integrity of assembly.

b. Potential drop in grounding connection. c. Receptacle grounding contact.

d. Accelerated aging.

e. Grounding pin retention. f. Mold stress relief.

g. Conditioning.

h. Abrupt removal.

i. Line blade retention.

j. Grounding contact temperature. k. Grounding contact resistance.

l. Fault current.

m. Connection and separation. n. Grounding path resistance. o. Strain relief.

Nonconformance to 3.6.14 shall constitute failure of this test.

4.6.16 Blade strength (plugs and male inlets only) (see 3.6.15). Devices shall be tested in accordance with 4.6.16.1, 4.6.16.2, and 4.6.16.3. The device shall be rigidly held in place in such manner as to withstand, without damage, the specified force, which shall be applied to each contact and shall be increased to the specified magnitude. The axial application of the force shall pass through the center of the hole in the contact. If the contact does not have a hole a force shall be applied at a point 3/16 inch from its free end.

4.6.16.1 Bending stress.

4.6.16.1.1 Perpendicular stress (plugs only). Unless otherwise specified (see 3.1) a force of 20 pounds minimum shall be applied in each of two directions parallel with the plug face and perpendicular to the axis of the contact hole.
