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.
A power cord, line cord, or mains cable is an electrical cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage (generally 100 to 240 volts ...
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.
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).
It was first published in April 2016 to provide a standard for travel adaptors suitable for the connection of a non-BS 1363 plug, or to a non-BS 1363 socket-outlet. It provides for an overall rating of 250 V AC, minimum current rating of 5 A, and a maximum of 13 A. Adaptors with BS 1363 plug pins must incorporate a BS 1362 fuse.
For example, high-current equipment can cause a fire when plugged into an extension cord with a current rating lower than necessary. Sometimes the cords used to plug in dual voltage 120 V / 240 V equipment are rated only for 125 V, so care must be taken by travellers to use only cords with an appropriate voltage rating.

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.
