Plug & Play Hot Tubs.

Zoomup

Sparkiemike recently mentioned plug and play hot tubs that are popular these days.

I came across one recently at a holiday cottage. It was just plugged into an outdoor weatherproof socket. The hot tub was quite small as hot tubs go. It sat on flagstones on soil in the garden. It was possible to have one foot in the water and the other on a flagstone.

The earthing arrangement was P.M.E.

I was not happy with that so I TT'd the socket, and converted it to an R.C.D. type socket. The circuit is R.C.B.O. proteced at the consumer unit, but I do like belt and braces R.C.D. protection is critical situations like this.

How many D.I.Yers will install these plug and play hot tubs in the garden without considering the electrical safety aspects?

Z.

    I have only seen two plug and play hot tubs. One had a 10mA RCD in the power cable. Apart from pressing the test button there were no accessible connections to test it properly.

    I have not seen the wiring on the second, apart from the extension cable out of an adjacent window, but it is mounted on wooden decking so the risk would appear to be low. 

    But as there do not appear to any reports of people receiving shocks from them are we worrying unduly about the risks. Especially when compared with the number of people dying from falls on stairs. ( over two per day)
