Exceptions could be devices such as illuminated "Exit" signs, which require connection to the power supply at all times. Each switch or means of operating a switch, for a socket-outlet shall be (a) as close as practicable to the socket-outlet, and (b) marked to indicate the socket-outlet(s) or the connected electrical equipment that it controls ...
A wiring diagram for parts of an electric guitar, showing semi-pictorial representation of devices arranged in roughly the same locations they would have in the guitar. An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing.
In electrical wiring, a light switch is a switch most commonly used to operate electric lights, permanently connected equipment, or electrical outlets. Portable lamps such as table lamps may have a light switch mounted on the socket, base, or in-line with the cord.
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 ...
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).
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.
Electrical panels, cables and firestops in an electrical service room at a paper mill in Ontario, Canada. Electrical panels are easily accessible junction boxes used to reroute and switch electrical services. The term is often used to refer to circuit breaker panels or fuseboxes. Local codes can specify physical clearance around the panels.
Generally the plug is the movable connector attached to an electrically operated device's mains cable, and the socket is fixed on equipment or a building structure and connected to an energised electrical circuit. The plug has protruding pins (referred to as male) that fit into matching apertures (called female) in the sockets. A plug is ...
