HI all
Wondering if a sparky can help me out. I'm hooking up power to an outdoor spa which requires 15amp single pahse minimum requirements. I'm having a qualified sparky hooking it all up just wondering about the wiring dimensions. The run is 35 metres in the ceiling then it goes 8 metres in conduit to the spa under concrete. Is 2.5mm wire ok for this? The run is about 43metres in total from spa to meter box and add in another 2 metres or so length of lead on the spa controller.
Thanks
