Wiring in a hot tub

Is this the right thing to use?

There's a spare 40A output on the consumer unit, but it's just an MCB, so no protection if something goes wrong.

I guess what I'm really asking is whether a 30mA RCD is the right thing to use where there's electricity, water and weather together, as opposed to all the other acronyms out there.

If your consumer unit is RCD proteced (which it should be) then there isn't a need for another one.

Edit: and yes an RCD is the correct protective device, it's just you should already have one

We bought our tub from a shop and they would not connect the tub to the house supply until they had a specific piece of paper work/certificate from a qualified electrician, if you want i will find paperwork tonight and let you know what info they wanted.

It's not in this case. It's a split load board, and the circuit that goes to the outbuilding where the tub will be powered from is just on a regular mccb. It does have a 30mA RCD in the garage on the feed to the outbuilding though, so I guess that would be ok, but for belt and braces and considering the application, I'd rather have another safety device as near to where the tub will plug in as possible.

ye it will do the job..

Not sure why you need 2 RCD protectors.

better to be sorry than safe i guess (lol)

we have just installed solar heating into our pool and hot tub.

£50 in parts and on a sunny day our 3500 litre pool goes up 3 degrees a hour.

hot tub if water diverted to there goes up 5 degrees a hour. :O)

MDPE tubing is amazing.......

If the outbuilding is fed from the non protected side of the house consumer unit, but then all outbuilding circuits are proteced from it's own rcd covered dis board then there's no need to add another. It can introduce problems with nusince tripping if anything. It won't be any safer.

It's like all these plug top rcds that people get told they must buy when they are buying lawnmowers and the like from b&q, or they won't be safe, then they go home and plug the rcd into rdc protected circuits anyway

i suppose two in a row is better than one that might not work, especially since no one seems to bother pressing the test button quarterly as advised!
