[QUOTE="Locus, post: 536901, member: 34772"] Star-connected motor. Brown/Black/Grey & Yellow/Green - Casing. Completely under what is 300/500V i.e. permissible nominal voltage of a cable, specified in volts. 300V is the maximum permissible effective value between the conductor and protective conductor whereby 500V is the maximum permissible effective value between the phase conductors. Usually, 600/1000V is used but I would like to know if it is a usual practice to use 300/500V and whether it is permissible. Thanks [/QUOTE]
