WebJan 2, 2013 · Thumb Rule: As a thumb rule we can say that 6.6KV unearthed cable is equal to 11k earthed cable i.e. 6.6/6.6kv Unearthed cable can be used for 6.6/11kv earthed system. because each core of cable have the insulation level to withstand 6.6kv so between core to core insulation level will be 6.6kv+6.6kv = 11kv BUY ELECTRICAL … WebApr 15, 2015 · Neutral = Blue. DC. Blue is always the conductor which is at earth potential or is the centre tap on bipolar systems, so if it's negative earth it's -, if it's positive earth it's + and if it's bipolar, it's 0V. Brown = + on negative earthed, unearthed or bipolar power supply. Grey = - on positive earthed, unearthed or bipolar power supply.
