In electricity supply design, a ring circuit is an electrical wiring technique in which sockets and the distribution point are connected in a ring. It is contrasted with the usual radial circuit, in which sockets and the distribution point are connected in a line with the distribution point at one end. Ring circuits are also known as ring final ...
In an electrical power distribution system, a ring main unit ( RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring-type distribution network. It includes in one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch ...
Ring, or ring final circuit (RFC) A ring circuit is a UK standard means for wiring domestic and other light commercial premises, not often seen elsewhere in the world; in effect it is a radial circuit whose final termination is made back to the originating distribution board, rather than at the last outlet or device serviced. De-energized circuit
A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node – a ring. Data travels from node to node, with each node along the way handling every packet. Rings can be unidirectional, with all traffic travelling either clockwise or anticlockwise ...
One of the other recommendations in the report was the introduction of the final ring circuit system (often informally called a "ring main"). In this arrangement a cable connected to a fuse, or circuit breaker, in the distribution board was wired in sequence to a number of sockets before being terminated back at the distribution board, thus ...
The designation NM XX-Y indicates, respectively, the type of sheathing (in this case, non-metallic), the size of the main conductors, and the total number of circuit conductors (exclusive of the grounding conductor). For example, NM 14-2 cable contains three conductors (two plus one ground) at 14 gauge, a size typically used for circuits ...
Components of an electrical circuit are electrically connected if an electric current can run between them through an electrical conductor. An electrical connector is an electromechanical device used to create an electrical connection between parts of an electrical circuit, or between different electrical circuits, thereby joining them into a ...
The ring oscillator is a member of the class of time-delay oscillators. A time-delay oscillator consists of an inverting amplifier with a delay element between the amplifier output and its input. The amplifier must have a gain greater than 1 at the intended oscillation frequency. Consider the initial case where the amplifier input and output ...
