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 ...
Amendment No.2:2004 to BS 7671:2001 implements the cable core colours introduced in the revision of CENELEC Harmonization Document HD 308 S2: 2001 Identification of cores in cables and flexible cords and agrees generally with BS EN 60446 : 2000 Basic and safety principles for the man-machine interface, marking and identification.
Cables are most commonly a single outer sheath containing separately-insulated line and neutral wires, and a non-insulated protective earth to which sleeving is added when exposed. Such cable is commonly referred to as twin and earth or simply T&E. Standard sizes have a conductor cross sectional area of 1, 1.5, 2.5, 4, 6 and 10 mm 2. With most ...
SY control cables are not suitable for fixed wiring applications in the UK requiring compliance with the requirements set out in BS 7671. [4]SY cable should not be used in areas exposed to ultraviolet light as it damages the outer sheath leading to cracking and then rusting of the braid as water penetrates the damaged sheath.
A wire or cable has a voltage (to neutral) rating and a maximum conductor surface temperature rating. The amount of current a cable or wire can safely carry depends on the installation conditions. The international standard wire sizes are given in the IEC 60228 standard of the International Electrotechnical Commission.

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 ]
However, the fact that the cable rating is 67% that of the circuit breaker, not 50%, means that a ring has to be significantly out of balance to cause a problem. In a ring circuit, if any poor joint causes a high resistance on one branch of the ring, current will be unevenly distributed, possibly overloading the remaining conductor of the ring.
