Hot tub supply

[Paul K]

Hi everyone,

I have a redundant 40amp fuse on its own breaker which was originally for a shower. It’s capped off in the loft, can I use this supply to power a hot tub?

Cheers in advance.

Theoretically - Yes, but it may need de-rating if the hot tub doesn't require such a large supply.
Presumably as previously for a shower it is a RCBO or otherwise RCD protected supply?

I would refer to the hot tub manufacturers electrical requirments

I’m a rank amateur when it comes to electrics, so d be getting a spark in to do the work. It would just be a lot easier and cheaper running it through the loft and down the side of the house than having it all redone.

Can the fuse be changed to a lower amp?

It can be reduced in size, but it would have to be rcd protected

That consumer unit looks like it has been adapted that mcb should not be located there and that Main Switch (RCD) is not an RCD.

Yes but would have to be an rcbo unless you are using armored cable ,but then it would need an rcd at hot tub end .much easier changing that to an rcbo but unsure if you would get a brand new rcbo in that range ,maybe someone else will know.im sure I'll be corrected im not that familiar or can't remember the layout of that type of boards but the mcb seems to be in the wrong side of mainswitch but maybe there's a manufactured piece of busbar feeding mcb .the live I believe would enter on the right hand side of mainswitch .its also only rated at 63 amps which seems odd if its your main board for house .it looks like it's been altered at some point .it also says rcd on it which it isn't. But your sparky will keep you right .do you no your earthing system type .does it say Pme on main cut out fuse

You beat me to it lol

I thought that but I think it is OK there is space to the left of that MCB for a 2nd MCB. It is a 2 Module CU.

The case must be able to be cut to suit the modules I am presuming. Got that from looking at an example online.

Of course the Main switch is labeled RCD which is not correct and is misleading.

This is most likely a Sub Board and if that is the case is the supply to this RCD protected perhaps?

Yes I think your right it was hard to tell from original picture I thought it was the main consumer unit .it would make sense with the 63 amp main switch
