Hi guys if you have a TNS system or TNCs is it mandatory to TT a outdoor hot tub ? Say TNS up to the rotary switch then earth rod from that point ? Thanks guys
If the installation is such that the installation could be seen as similar to an outdoor swimming pool, then the regs would recommend either a grid beneath, or TT.
