Best electrics for a hot tub outside

Leeds2020 · May 19, 2021

Hello, I want to connect a hot tub outside on the patio. It is a plug and play with a standard 13 amp plug. It is around 10m away from the house. I have been told it draws around 7 amps when all equipment turned on. Is it best to connect an outside socket somewhere near using 2.5mm twin and earth cable with two cables back to the ring main or 1 armoured cable as a single spur from the closest ring main

As long as the socket you are spurring from is not already a spur in itself, I would go with the SWA method. the first option is difficult to comprehend "2 cables back to the Ring Main" remember to to alow for RCD protection, if you are not sure get a pro in to do it for you, that will save you the hassle of notification and certification, in my opinion anyway good luck.

It would be good to have it on its own separate circuit so that in worst case scenario if your exterior socket let in water it would trip its own individual rcbo rather than taking out your socket circuit, however this can also be achieved by fitting a double pole switch before the socket to isolate it in the event of a fault. But both options are technically fine.
