NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical arcing in the branch circuit wiring as well as in cords and plugs. An AFCI device is designed to trip quickly when it detects potentially dangerous arcing that could start a fire, but not trip with harmless arcing as part of ...
A power cord, line cord, or mains cable is an electrical cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage (generally 100 to 240 volts ...
Plugs and power cords have a rated voltage and current assigned to them by the manufacturer. Using a plug or power cord that is inappropriate for the load may be a safety hazard. For example, high-current equipment can cause a fire when plugged into an extension cord with a current rating lower than necessary.
Switched-socket outlets with interlocks are described in IEC 60309-4 standard and are commonly used to enhance electrical safety in industrial plants. The interlock cuts power to the socket when nothing's plugged in and locks any plug in the socket until the power is turned off.
Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. Thousands of configurations of connectors are manufactured for power, data, and audiovisual applications. [3] Electrical connectors can be divided into four basic categories, differentiated by their function: [4]
While larger sizes are still used to feed power to electrical panels and large devices, aluminium wiring for residential use has acquired a poor reputation and has fallen out of favour. Aluminium conductors are still heavily used for bulk power transmission , power distribution , and large feeder circuits with heavy current loads, due to the ...
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).
