There are generally three different systems in use by spa manufacturers.
10 amp ‘plug in’
These spas can be plugged into a normal household socket as long as it is protected by a RCD or ‘residual current device’. Because of the low power rating of a standard household socket, spas using this system generally use smaller than average pumps or heaters. They will also turn the heater off automatically when the jet pump is turned on.
15 amp ‘plug in’
This system can be used when the spa is set up so that the heater turns off when the main pump turns on. Whilst this is perfectly acceptable in warmer conditions and gives the manufacturer the ability to install larger pumps and heaters, it should be avoided if the spa is to be run in very low temperatures. It is also not possible to run a spa on this system if it has two jet pumps.
32/40 amp ‘hard wire’
This system allows for the heater and jet pumps to all run at the same time. It is also required on spas that operate two jet pumps. Whilst this system requires more investment than the plug in option, it does allow for a higher performance hydrotherapy spa to be chosen.
Endless Spas recommend hard wiring your spa for the best spa expereience, however we do recognise that sometimes this is not possible. Endless Spas offer all three electrical options (depending on spa capabilities).
