Getting an electric shower 10.8kw.
Got 10mm t+e cable and route from shower room is easy up to the loft and across. But down to the supply is not. Will have to go through another bathroom. I intend to run cable vertically down wall about 2" away from another perpendicular wall. Wall is outside wall with plasterboard. As it is within 150mm is it ok to just cap the cable and fill with plaster?
Next problem is that although the house is only 20 yr old it has memera fuse box. How can an mcb be connected into this?
I just want to do the donkey work and let an electrician check and make the connections. I dont want to connect the mcb myself just want to know what preparations might be needed.
Any advice welcomed.
