The ground tab is designed to be attached to the outlet faceplate screw, which is supposed to be connected to the building electrical ground. A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
Generally, 6-series non-locking plugs are used for such appliances as large room air conditioners and commercial kitchen equipment; the occasional home arc welder also uses 6-50. [25] Single-phase 6-50 is commonly used on farms for silo unloaders, and is used with a 6-gauge flexible power cord up to 200 ft (61 m) long.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
Power system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults [citation needed] through the disconnection of faulted parts from the rest of the electrical network.
Motor capacitors are used with single-phase electric motors [3]: 11 that are in turn used to drive air conditioners, hot tub/jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example. [1] A "dual run capacitor" is used in some air conditioner compressor units, to boost both the fan and compressor motors. [1]
A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...
The voltage rating does not need to be symmetrical; "semi-polar" capacitors can be made with different thicknesses of oxide coatings, so they can withstand different voltages in each direction, [38] but these bipolar electrolytic capacitors are not adaptable for main AC applications instead of power capacitors with metallized polymer film or ...
