Extension lead with extra large socket for hot tubs with a 13A RCD plug

  • Sale
  • Regular price £36.99


Heavy duty extension lead, designed to connect high power draw appliances with a UK 13A RCD plug (an RCD plug is much larger than a standard 13A plug, and will have test/reset buttons). It is also compatible with standard UK 13A plugs. It is not compatible with 16A European plugs.

The extra large socket which is compatible with plug RCDs, which are too large to enable the cover to shut on any other socket. It is supplied configured with the socket at the top, to allow sufficient space for the body of the RCD. Whilst almost all hot tub plug RCDs have the pins at the top of the unit (as shown below), if your RCD has the pins at the bottom, please let us know so that it can be configured appropriately. 

Available in 2m, 5m, 10m and 15m lengths - select the required length from the drop down list above. 

Available with either:

  • No RCD - Please only consider this option if you are sure that the socket you will be connecting the extension lead to is already RCD protected. See Do I need an RCD? for further guidance.
  • In-line (30mA) RCD - An RCD is a life-saving device which is designed to reduce the risk of receiving a fatal electric shock. The unit is IP66 rated weatherproof. The in-line RCD is vital if the socket you will be connecting the extension lead to is not already be RCD protected. 
  • 13A UK rubberised plug.
  • Weatherproof IP66 rated single socket, suitable for an RCD plug. An IP66 rating means that the socket is protected against powerful water jets (we don't advise that you test it of course!).
  • Can be wall mounted. If wall mounted, as with any electrical enclosure, a small drain hole must be drilled at the bottom of the unit (where marked and according to the instructions provided). This is to reduce the risk of condensation building up.
  • To guard against unauthorised access, the socket can be locked shut with a small padlock (max 5.5mm diameter) available here.
  • 1.5mmsq cable for high current applications, thicker than standard DIY extension leads which commonly use 1.25mmsq. The thicker cable is used in this lead to keep resistance and voltage drop to a minimum. It is for this reason that the maximum length is 15m.
  • Industrial specification H07RN-F rubber cable, specifically manufactured for harsh environments with high mechanical, chemical, water and UV resistance. Flexibility and performance is retained over a wide temperate range (-25 to 55°C). Find out what’s so special about this cable
  • Due to the relatively high current used by hot tubs, we recommend checking the plug fuse clips remain tight annually, or if the plug ever feels warm, using these instructions.
  • PAT tested.

    Further recommended precautions if used near a body of water:

    • The socket must be cited as far away as possible from any hazard and in no circumstances closer than 2m to any body of water (IET Wiring Regulation 702.32).
    • In higher risk situations, the socket must be kept 30cm off the ground (IET Wiring Regulation 702.53). We are currently developing a plastic ground spike, which will be available later in May 2020) 

    It is the responsibility of the user to consider the IET Wiring Regulations, manufacturer's guidance, the safety of the supply and any other relevant risks, before deciding whether to use an extension lead for any given application. This is of particular importance in circumstances where there is an increased risk of electric shock. If in any doubt, consult an electrician.
