[QUOTE="Apache, post: 86606, member: 828"] A short circuit is where there is contact between phase and neutral and the current can flow between without passing through an accessory. In your example it would depend how the cable was severed. If you used your nice pair of VDE sidecutters then chances are you would short L-N and trip MCB or short L-E and trip the RCD. If you were careful and nibbled in from each side it may be possible to cut it without tripping anything, if the blade never contacted L&N simultaneously. If you isolated, cut cable then re-energized the circuit then there would (likely) be no L&N contact and no short circuit. The Vet thinks..... [/QUOTE]
