Hi all, we're renovating our property and looking to install a sauna (7kw), electric shower (9kw), outdoor heater (4kw), small lights (200w) and an electric point for things like a lawn mower. In total, I was estimating around 22kw if we had all devices on with no diversity. The current fuse box in the basement is getting quite full and in the future we're planning to put a car charger in that one which I imagine would be 7kw-9kw. Would it make sense to put another fuse box in the garden and run a 10mm cable from the one in the basement to the one in the garden? I think the cable running from the main road into the house is only 16mm? The overall distance between the two fuse boxes would be 22 meters. The cable would be running through a 32mm conduit buried under the concrete. The main thing I'm thinking is that if I switched on everything in our house such as lights, induction hob, ovens, sockets, and everything in the garden mentioned above, etc, it would come to a total of 76k for the overall house. Many thanks in advance.
