Three phase installations have traditionally used red, yellow and blue for the phase conductors and black for the neutral conductor. However, where three-core cables marked in the new three-phase colours are used for single-phase applications, it is proposed that, as a convention, the black core is used for the protective conductor, the brown for the phase conductor and the grey for the neutral. Please take the opportunity to download our corporate product brochures. Protective conductors remain green and yellow. Local utilities often have their own color code requirements, but again, that would not apply inside of a … For many years the supply voltage for single-phase supplies in the UK has been 240V +/- 6%, giving a possible spread of voltage from 226V to 254 V. For three-phase supplies the voltage was 415 V +/- 6%, the spread being from 390 V to 440V. If you require two or more electricity meters then you need a three phase supply. This brings the UK more closely in line with three phase wiring practice in mainland Europe. Aldermaston, Old and new phase conductors should be fitted with sleeves marked L1, L2 and L3 and neutral conductors should be fitted with sleeves narked N to avoid any possible confusion.
