Plug & Play Spas
These will be one pump spas with either a 2kw or 3kw heater and a 13/16amp supply will suitable for these hot tubs. Although these are called “plug and play” these spas do not arrive at your house with a cable and plug attached. You will ideally need a 16amp IP44 Commando Outdoor Switched Socket or a 13amp IP66 Switched Socket (for a 3 pin plug) sited somewhere near to the location of your proposed spa.
Both options will then require a suitable length of cable to reach from the socket to the hot tub control box (armoured if the cable is to be exposed) with the appropriate plug on one end this will either be a 3 pin plug for the 13amp option or a 16amp Commando Plug for the 16amp version and bare cable ends at the spa end, these bare ends will be connected into the PCB board in the control box, please ensure the cable is long enough to reach anywhere inside the spa cabinet.
