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.

An SY control cable is a flexible instrumentation electrical cable designed for measuring, control or regulation in the field of process automation. [1] It is a flexible multicore cable , with (class 5) [ which? ] copper conductors and a galvanised steel wire braid (GSWB) for mechanical protection.
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
These are sometimes called “chain-suitable,” “high-flex,” or “continuous flex” cables. A higher level of flexibility means the service life of a cable inside a cable carrier can be greatly extended. A normal cable typically manages 50,000 cycles, but a dynamic cable can complete between one and three million cycles.
Tri-rated cable is a high temperature, flame retardant electrical wire designed for use inside electrical equipment. Tri-rated cable meets the requirements of three different international standards: BS 6231, UL 758, and CSA 22.2. [ 1 ]
Yellow NEMA 5-15 extension cord NEMA-1 extension cord, common in the United States Extension cord reel (Germany). An extension cord (US), extension cable, power extender, drop cord, or extension lead (UK) is a length of flexible electrical power cable (flex) with a plug on one end and one or more sockets on the other end (usually of the same type as the plug).
The American National Electrical Code, for theater use, requires (article 520.68(A).1) cables to be "extra hard usage" rated, and such cable is generally known in the US as SOOW cable. Cables meeting the SOOW spec can also be manufactured to be rated as H07RN-F, so-called "harmonised" cable, and such cable can be used both in the US and Europe.
