I don't know..... Go look in your box......SERIOUSLY.......
The legend identifying the breakers inside an electrical panel is typically just referred to as the "breaker directory" or "circuit directory." It is a list that indicates which circuit each breaker controls in the electrical panel.
Recepticals, light switches, light fixtures etc.... Electrical devices is a generic term for any device that utilizes electricity.
As its name suggests, electrical engineering involves the study and application of electricity, electrical and electronic systems. Electrical engineers are professionals who design, develop, test and maintain electrical devices, including motors, communications systems, electronic equipment and a long (and growing) list of devices that the operation relies on electricity.
Iphones and Ipads were both no created in the 1950s
VDE is the acronym for the full German name of what is known in English as the German Association for Electrical, Electronic and Information Technologies.
The Motor converts electrical into mechanical energy
Devices used to open an electrical circuit are called OCPD's. (overcurrent protection devices) The most common are circuit breakers and fuses. In commercial motor starters they often employ another OCPD called a "heater" (UK thermal fuse) which is a metal strip which melts like the element in a small fuse when too much current (amps) go through it. They devices are in the circuit primarily to protect the wiring and devices they power. Circuit breakers such as in your home panel do protect you from a "shorted" circuit. Another safety and most common in residences are GFCI's or ground fault circuit interrupters (UK ELCB, Earth Leakage Circuit Breaker or RCD, Residual Current Detector) which come as both a receptacle (female plug) or as a circuit breaker.
A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.More informationA sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box"."Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".
An electric motor or a generator changes energy from or to electromagnetic energy, respectively.
The device for receiving electric plugs is called a socket or electrical outlet. It provides a connection point for electrical devices to access the electrical supply from the wiring in a building. Sockets can come in various types and designs depending on the region and the specific electrical standards.
what is name for input devices?
Electric power (how fast energy is being converted into or out of electrical energy) is measured in Watts. Electrical energy is measured in Joules. i Watt for 1 second is 1 Joule. 1000 Watts for 3600 seconds is 3.6 Megajoules, also known as a kilowatt-hour or a Unit of electrical energy.
