Electrical Requirements - What do I need for my hot tub?

Most of our Hot Tubs need a dedicated 32 amp power supply to be installed at your house. What does this really mean? Well, you would need to get an electrician to visit and present him with our electrical requirements guidelines which you can download in PDF format below. Show him where you would like your new Hot Tub and ask him for a quotation. The cost of this can vary and it all depends on your individual property. The distance from the house is also a factor in this calculation.

Electrical Installation Guidelines

  1. The power supplied to the spa must be a dedicated circuit with no other appliances connected.
  2. The spa must be permanently connected (hard wired) to the power supply.
  3. No plug-in connections or extension leads are to be used.
  4. A 30ma RCD (residual current circuit device) must be installed at the power supply in the property.
  5. The spa must be supplied with 32 amp feed 220/240 volts.
  6. A 32 amp circuit breaker should be installed and clearly marked "spa".
  7. The spa should be fed with a 6mm 3-core steel wire armoured cable.
  8. Isolation should be via a 32amp 2-pole rotary weatherproof switch.
  9. The work must be carried out in accordance with the current (17th edition) IEE wiring regulations and by a qualified electrician.
  10. The cable needs to be run to the isolator switch (isolator to be sited a minimum of 2mtrs and ideally a maximum of 5mtrs from the spa) with a minimum 5-metre tail & gland sufficient for connection to the spa. This is how the installation must be left (safe) at this stage.
  11. A date and time for the final connection and testing will be arranged between ourselves and the electrician. Our Installation team will deliver and position the spa and also route the cable to the connection point. The electrician will return for final connection & testing on the day of installation.

Please note that these instructions are for guideline purposes only and any electrical work should be carried out or inspected by a qualified electrician prior to installation of the spa.
