Hot tub question for the experts.

[Jester]

This is probably going to be a really silly question but I need to know just for my own peace of mind.
I have a hot tub, an intex inflatable job. The power cable goes into an rcd then into a normal plug which is plugged into a normal house socket, (well away from the water I might add.) When I changed the plug it has no earth wire just the brown and blue. The tub has come from a friend and it's the original cable. Is this right? It is all plugged in and up and running but I don't want to get in it if it's unsafe in any way.
I realise I probably sound like a complete noob, it's because I am! I just thought it should have the earth wire or is that what the rcd is for? My friend says his tub is the same.
Appreciate any help at all! Cheers folks.

Might just add that obviously I'm not an electrician. Lol!

hi ,it may well be whats called a class 2 appliance that does not need an earth,if you look where the cable attaches you might see a symbol with a picture of a square inside a square,this means its double insulated and no earth needed

It does indeed have the square within the square. Thanks for the advice. Does this mean it's safe to use?

it should be fine. double insulated appliances don't require earthing as there are no exposed metal parts. the RCD operates on an imbalance between L and N, so will work without any earth on the appliance.

Is it safe to use? depends has it been maintained and installed correctly? has it been subjected to any tests (ISITEE) In Service Inspection and testing of Electrical Equipment you might know it as Portable Appliance testing (PAT)

Based on what you have said and providing it's all in the original manufacturer's condition I would say yes

I can never get used to the idea of electricity and water together with me or anyone for that matter. While no doubt it is safe, I feel a bit superstitious about things like that such as an electric shower.

Do you have the manufacturers install instructions? Sounds class 2 to me

Thanks for all the replies folks. It's greatly appreciated.
