The standard wiring colours in the UK are (as of 2006) the same as elsewhere in Europe and follow international standard IEC 60446. This colour scheme had already been introduced for appliance flexes in the UK in the early 1970s, however the original red/black colour scheme recommended by the IEE for fixed wiring was retained until 2006, albeit ...
Plug adaptors permit two or more plugs to share one socket-outlet, or allow the use of a plug of different type. There are several common types, including double- and triple-socket blocks, shaver adaptors, and multi-socket strips. Adaptors which allow the use of non-BS 1363 plugs, or more than two BS 1363 plugs, must be fused. [79]
Note that the wires in the 6-wire cable are coloured with two colours in a ratio of four to one in length, with the first colour mentioned being the predominant one, e.g. if the indicated colour of the wire is W-B then the wire will be coloured white for 12 mm, then blue for 3 mm and so on.
Hubbell's first plug design had two round pins which differed from those already in use in Europe in that the tips of the pins had annular detents similar to those of present-day jack plugs to positively retain a plug in its socket. In one patent, U.S. patent 774,250 a plug was used with a socket which screwed into a lampholder (like the early ...
For example, telephone cables in the UK typically have a BS 6312 (UK standard) plug at the wall end and a 6P4C or 6P2C modular connector at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight-through cable from the BT plug (which uses pins 2 and 5 for the ...
The cable core colours are described in IEC 60304 (1982-01), Standard colours for insulation for low- frequency cables and wires. The three-phase phase colours are brown, black and grey instead of red, yellow and blue. Where a circuit includes a neutral or mid-point conductor identified by colour, the colour used shall be blue.
The color combinations are applied to the insulation that covers each conductor. Typically, one color is a prominent background color of the insulation, and the other is a tracer, consisting of stripes, rings, or dots, applied over the background. The background color always matches the tracer color of its paired conductor, and vice versa.
Die-Cut Plug Wiring Diagram Book is an artist's book by the English artist Mark Pawson, originally published in early 1992. [1] Originally consisting of 36 full-size reproductions of British AC power plug wiring diagrams printed in various colours, the book has become celebrated as an example of English sociological art , and is sometimes ...
