Three-prong plugs do not fit into the older, two-prong receptacles. [7] When used as intended, the ground pin of the 3-wire receptacle is to be connected to a grounded cover screw, or to an external ground. In 1969, Underwriters Laboratories mandated three-prong plugs on major appliances for safety. [7]

[2] [3] In a 2005 article appearing in SWAT magazine it was deemed to be superior to the M16A2 "bird cage" flash suppressor and the Yankee Hill Machine Phantom Flash ...
There is an obvious relationship between the texts of 2 Peter and the Epistle of Jude. [6] Comparing the Greek text portions of 2 Peter 2:1–3:3 (426 words) to Jude 4–18 (311 words) results in 80 words in common and 7 words of substituted synonyms. [7] The shared passages are: [8]
All NEMA 5 devices are three-wire grounding devices (hot–neutral–ground) rated for 125 V maximum, with the 5-15, 5-20 and 5-30 being grounded versions of the 1-15, 1-20 and 1-30, respectively. The addition is a 3 ⁄ 16-inch (4.8 mm) diameter round or U-shaped ground pin, 1 ⁄ 8 in (3.2 mm) longer than the power blades (so the device is ...

CEE 7/1 wall socket, accepts CEE 7/2 (unearthed) plug and also CEE 7/4, CEE 7/6 and CEE 7/7 (earthed) plugs. The International Commission on the Rules for the Approval of Electrical Equipment ( IECEE ) was a standards body which published Specification for plugs and socket-outlets for domestic and similar purposes as CEE Publication 7 in 1951.
SANS 164-3 defines a 6 A plug and socket based on the BS 546 5 A. The South African Wiring Code now defines the plug and socket system defined in SANS 164-2 (IEC 60906-1) as the preferred standard, and it is expected that SANS 164-1 and SANS 164-3 devices will be phased out by around 2035. [96]
