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 ...
Open Pluggable Specification (OPS) is a computing module plug-in format available for adding computing capability to flat panel displays. The format was first announced by NEC , Intel , and Microsoft in 2010.
A 1992 guide book on proposal preparation defined a brassboard or a breadboard as "a laboratory or shop working model that may or may not look like the final product or system, but that will operate in the same way as the final system". The definition of a breadboard was further narrowed to purely electronic systems, while a brassboard was ...
However, this ground-wire style of cheater plug was discontinued when it was noted that a loose unattached grounding wire could accidentally become connected to the "hot" blade of a nearby outlet, potentially leading to electric shock. As an additional failure mode, the thin flexible wire could break unnoticed inside the insulation.
A breadboard, solderless breadboard, or protoboard is a construction base used to build semi-permanent prototypes of electronic circuits. Unlike a perfboard or stripboard, breadboards do not require soldering or destruction of tracks and are hence reusable. For this reason, breadboards are also popular with students and in technological education.
Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...
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 ...
The switch does not fully disconnect the device from its power supply. This may appear on a toggle switch opposite a power on symbol, alone on a pushbutton that places the device into a standby state, or alone on a button that switches between on and standby. Alternatively, under IEEE 1621, this symbol simply means "power". [9]
