Ir Dr KM LEUNG . These systems are common in home and office environments. The reason that BS7671 no longer permits the phase colour to be used for the L of a single-phase circuit is quite simply one of safety. Brown replaces the old-style Red for the Phase, or Active connection; Blue replaces the old-style Black for the neutral conductor; and the new style earth lead is green-yellow striped replacing the older green wiring. For three-phase cables, rather than accept the European consensus – which is to colour code the phases brown or black – the UK committee considered alternatives. The 'units' are pieces of equipment that are identical (production line testers) and are both powered and controlled by the single cabinet (that is fed by a 3 phase supply). Training for Trade Workers . The AC power cable color code is nearly similar to the code used in the USA except exclusion of bare copper from ground wire. The old wiring colour codes did not account for proper phase rotation, therefore most of Europe now abides by IEC (International Electrotechnical Commission) for single phase and three phase electricity. Quoting from authoritative codes & standards for each region we provide a table summarizing the current and prior wiring color code conventions used by electricians in building wiring. The AS/NZS 3112 Consists of 3 flat pins, two in an inverted "V" shape, the top left pin is Active, the top right pin is Neutral, and the lower pin is Earthing. Wiring Regulations saw a change to harmonise the UK wiring colours with European cable colours for consistency and to avoid confusion. The old cable plug colour codes did not account for proper phase rotation, therefore most of Europe now abides by IEC (International Electrotechnical Commission) wiring colour codes for AC circuits. Single phase colour are the same as US NEC, Live - black, Neutral - white/grey, earth - green. All protected with RCD and MCB. The internal wiring of equipment may come with European colour codes (brown, gray, black, blue) - this is permissible by AS 3000. There are actually 12 units and phase 1 from the cabinet is powering units 1,4,7,10. The incoming 240V power is split into two legs.
