I am soon to be helping a friend with his electrics on his canal boat, he is looking at putting a small consumer unit, with a circuit for sockets and another for lights and upgrades to sockets wiring etc etc
All sounds easy enough but I am wondering how to select the correct short circuit protection, as the PSCC from the inverter is not very high, so even using a B16 MCB for the sockets the PSCC from invertor is well under 80A therefore in the event of a short circuit fault it will not meet required disconnection times etc. and if I got with a low-value MCB then it will cause nuisance tripping from over current.
Any ideas or is there something I am missing
Thanks
Marcus
