Having a hot tub or jacuzzi in your garden is getting more and more popular. The price of hot tubs and jacuzzis has fallen meaning they have become much more accessible to anyone with enough garden space looking for some bubbly fun.
Hot tubs aren’t specifically mentioned in BS7671 presently but a good, registered electrician will use engineering judgement and knowledge of the wiring regulations when designing the installation to make sure it is safe and durable.
What power supply do I need for my Hot tub?
Whether you go for a fixed rigid unit or the Lazy spa inflatable type you need to make sure they are installed properly and the circuit tested. An inflatable lazy spa ‘plug and play’ type will normally need a 13Amp supply whilst a hard wired rigid style hot tub will normally need a 32/40Amp supply.
If you are thinking of getting a hot tub or have one and are concerned about the electrical supply then take a look at the checklist of what should be in place below:
- A 30ma RCD should be protecting the supply, this should be tested by the installer to check it is disconnecting within safe limits.
- The correct type of cables should be used for the load and to protect against damage
- The socket or isolator should be 2m from the edge of the tub.
- Weatherproof and splash proof isolators and sockets should be used.
- For a hard wired 32/40A tub we would recommend using a rotary isolator.
- Where the manufacturers require a ‘tail’ it should be made of flexible but resilient material.
- The tail should be under no strain and secured as not to be a trip hazard.
- The circuit should be tested on installation to ensure it is adequately earthed.
Hot tubs are a lot of fun. Getting them installed properly from the start will keep the users safe and is likely to increase the lifespan of the hot-tub or jacuzzi.
