I did a sub main for a bathroom...
had to route the cable around the outside of the house and it ended up being 35m long
It had a 9.5kW shower, 2kW downflow, Selv extractor fan & 38w 2d fittng; so with taking everything into account I had to use a 800 KMF with a 50A fuse and 25mm 3 core SWA... feeding a Metal clad CU just outside the bathroom & RCBO's on all circuits
This was all to get the volt drop and Zs in limits (It ended up only just within limits)... the supply was TNS with a Ze of 0.41

'kinell, how bigs your house?
Not my house.... it was a B&B and this was for their private quarters.. and the cable did have a bit of a rambling route, the worst part about it all was that it had to go past the bathroom and then back in to get to where I wanted it!!!
