The current (as of 2013) devices are referred to as "combination type." An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) [1] is a circuit breaker that breaks the circuit when it detects the electric arcs that are a signature of loose connections in home wiring. Loose connections, which can develop over time, can ...
In electrical and electronic engineering, a daisy chain is a wiring scheme in which multiple devices are wired together in sequence or in a ring, [1] similar to a garland of daisy flowers. Daisy chains may be used for power, analog signals, digital data, or a combination thereof.
In building wiring, multiway switching is the interconnection of two or more electrical switches to control an electrical load from more than one location.A common application is in lighting, where it allows the control of lamps from multiple locations, for example in a hallway, stairwell, or large room.
The neutral wire is identified by gray or white insulated wire, perhaps using stripes or markings. With lamp cord wire the ribbed wire is the neutral, and the smooth wire is the hot. NEC 2008 400.22(f) allows surface marking with ridged, grooves or white stripes on the surface of lamp cord.
Intentionally crossed wiring in the crossover cable connects the transmit signals at one end to the receive signals at the other end. Many network devices today support auto MDI-X (automatic crossover) capability, wherein a patch cable can be used in place of a crossover cable, or vice versa, and the receive and transmit signals are ...
3. Control devices are always shown between L1 and the output device. Control devices may be connected either in series or in parallel with each other. 4. Devices which perform a STOP function are usually connected in series, while devices that perform a START function are connected in parallel. 5. Electrical devices are shown in their normal ...
GFCI devices come in many configurations including circuit-breakers, portable devices and receptacles. Another safety device introduced with the 1999 code is the arc-fault circuit interrupter (AFCI). This device detects arcs from hot to neutral that can develop when insulation between wires becomes frayed or damaged.
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 ...
