[QUOTE="Andy™, post: 446019, member: 2012"] 11kw at 230v is 48a. depending on how its installed, 6mm can carry anything between 29 & 51a. thing is, if its installation method is rated to lower (i.e 46a if its clipped direct, or 32 if its enclosed in conduit / trunking) but on a 50a MCB, then it wont trip however the cable could overheat how many circuits did he install at the end of the cable and how many sockets? for something like that where you dont want power to trip, id be looking to install a larger supply to a board feeding many circuits each with a few sockets rather than a few circuits with lots of sockets. could even go as far as installing 2 submains & 2 boards feeding sockets and split everything between them, but you still have a common failure point at the service head / external power faults [/QUOTE]
