The ring starts at the consumer unit (also known as fuse box, distribution board, or breaker box), visits each socket in turn, and then returns to the consumer unit. The ring is fed from a fuse or circuit breaker in the consumer unit. Ring circuits are commonly used in British wiring with socket-outlets taking fused plugs to BS 1363. Because ...
Some telephone technicians used mnemonic phrases, such as red-right-ring-rear, or ring-right-red-rough, to remember that the red wire connects to the right-side post in the wall jack and to the ring on the plug and to the rear lug on main distribution frames. Sometimes rough or ridge was added for jumper wires with a tactile code. [citation needed]
In this use, the bead is a simple form of a balun. Ferrite beads are one of the simplest and least expensive interference filters to install on preexisting electronic cabling. For a simple ferrite ring, the wire is wrapped around the core through the center, typically five or seven times.
Ring style wire-end crimp connectors. The connectors in the top row of the image are known as ring terminals and spade terminals (sometimes called fork or split ring terminals). Electrical contact is made by the flat surface of the ring or spade, while mechanically they are attached by passing a screw or bolt through them.

T and R: Tip and Ring – the ground and battery of the receiver voice pair; T1 and R1: the ground and battery of the transmitter voice pair; 4-wire E&M uses a 4-wire (2-pair) transmission path for the voice signal. 2-wire E&M uses a single pair for both transmit and receive voice signal. This is much inferior to 4-wire E&M as the 2-wire ...
A number strip would be peeled out and wrapped around the wire near the end. Wire numbers were made up of a series of the number strips so wire 1051 would be four strips. There are also pocket sized printers that print onto an adhesive backed label that can be wrapped around the wire. The basic format for relay logic diagrams is as follows: 1.
