Hope to bottom this out here
from the main consumer unit at home I have a 80 amp RCCB with a B40 mcb connected to this I have a 16mm SWA going to a barn approx 15m away inside the barn I have another CU with 3 circuits a B32 mcb for 8 sockets (rarely used) a B6 for lighting and a B40 from which a 10mm SWA powers a static caravan.
I am extending the barn and want to include potentially a 6 KW sauna heater and potentially run a 6 KW shower,
Main question is the 16mm from the barn to the house sized ok for my plans.
I may have to put a sketch of the configuration as i do not think I have described it well enough, basically I can upgrade everything in the barn mcbs etc,
the sauna I have provisioned 10mm TE cable and the shower 6mm TE (i may have to go for a lower KW shower.
Hope i can get some help here....
