A receptacle tester being used to check for some types of improper wiring of an outlet. For this particular tester, proper wiring is indicated by the two yellow lights. The outlet tester checks that each contact in the outlet appears to be connected to the correct wire in the building's electrical wiring. It can identify several common wiring ...
Compared to the 5-15P plug, the 5-20P plug has the neutral blade rotated 90° and shifted so its inner edge is approximately 1 ⁄ 2 in (12.7 mm) from the hot blade. The 5-20R receptacle has a T-shaped neutral hole, to accept both 5-15P and 5-20P plugs.
The flat parallel plug blades are polarized to prevent the hot and the neutral connections from being reversed. In addition, many versions have a molded obstruction bump on top of the adapter, to block the grounding prong and thus physically prevent forcible insertion of a 3-prong plug in the wrong orientation.
Leg as in "hot leg" refers to one of multiple hot conductors in an electrical system. The most common residential and small commercial service in Canada and the U.S., single split-phase, 240 V, features a neutral and two hot legs, 240 V to each other, and 120 V each to the neutral. The most common three-phase system will have three hot legs ...
The plug sides are shaped to improve grip and make it easier to remove the plug from a socket-outlet. [55] The plug is polarised, so that the fuse is in the line side of the supply. [ 56 ] The flexible cord always enters the plug from the bottom, discouraging removal by tugging on the cable, which can damage the cable. [ 57 ]
The term plug is in general and technical use in all forms of English, common alternatives being power plug, [1] electric plug, [2] and (in the UK) plug top. [3] The normal technical term (in both British and International English) for an AC power socket is socket-outlet , [ 4 ] but in non-technical common use a number of other terms are used.
A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit.
"Switched socket-outlets and connectors with or without interlock" applies to self-contained products that combine within a single enclosure, a socket-outlet or connector according to IEC 60309-1 or IEC 60309-2 and a switching device, with a rated operating voltage not exceeding 1000 VDC or VAC and 500 Hz, and a rated current not exceeding 800 A.
