Lacking space in the box

[uksparks]

Hi,

i need to some how get a feed to a hot tub in here too...

any thoughts?

i was thinking it may be possible to rip the existing switch fuse out and stick a mini cu in with a 63a MCB and a 32a? I need to terminate some SWA in there too.

i wont go in to the finer details but this is the only place I can get a supply from and I can't mount anything outside the box as they don't want to do that.

i just need to split the tails and put a 32A supply out to the hot tub.

Oh and mounting it inside the house behind the box is a non starter.

There is also no room at all in the existing cu which is in the middle of the house and verging on inaccessible and certainly not in a place to even consider routing a cable to.

I'd say that if they want the hot tub they have to be realistic mate and actually make the job possible for you - the only sensible way I can see is a separate weatherproof box adjacent to the meter box to house your new switchgear.
The use of 6 x 4" or thereabouts adaptable boxes rather than the small covers you can get for the switchfuse is a bit of a bodge too.

Could you not remove the switch fuse and adaptable boxes and fit a 2way metal Cu in its place as you suggested?
Then just gland in the SWA?

I wouldn't replace the switch fuse for a CU.

I agree removing the switch fuse for MCB wouldn't be the best thing,

I think looking at it, the only way is to go outside the box.

ok, so suppose I do that, looking at it, where would you mount Henley blocks to split the tails? I didn't think you were meant to mount in the sides.

also I think it may look a bit crap if you then take tails and earth out of the bottom then into the enclosure, so maybe it could be put in copex or something or I don't know.

i did think that but 'think' it will probably not be so straight forward as I'm unsure how the cables enter at the bottom and it will all probably go horribly wrong and I'd wished id not entertained touching it.

what about building something yourself if it will fit to replace the switch fuse. maybe an open fronted enclosure, main switch, fuse holder and another fuse holder or mcb for the hot tub. https://www.europacomponents.com/product-22x58mm-fuse-holders.html

With care you could probably mount the blocks in the top of the meter box to the left of the meter, the extra box could go right up tight to the side of the meter box with the tails and earth coming through the side then apply silicone to ensure a good seal.

Thats bot a bad idea Lee, I'll have a look at it on Monday and see what I can come up with. I'm sure I'll be able to get round it some how.

The fuse will possibly end up falling out and the meter being moved by a fairy hard to the left hand side yet..

That may be beneficial.

An mcb isn't equivalent to a fuse so is not sensible for a straight swap

I know this.
If it's a small domestic house on a 63a CB would be fine.
Or just put a fuse holder in the CU as people have mentioned above.
Most manufactures list them, most take 2modules.
