Hi all, no doubt I'll get lots of negative comments on this but really hoping someone can help.

I need to get power to my shed and also to a Hot Tub by the shed and was thinking of killing 2 birds with one stone and wanted clarification if my plans are OK or not.

My thought is to run approx 20metres of 10mm t&e from a 50a RCBO in main consumer unit to a secondary unit with a 16amp RCBO and 32amp RCBO then have a 2 or 3 socket radial from the 16a and them approx 5metres 6mm t&e from 32a RCBO to rotary isolator then flex to Hot tub

Are there any issues with this or better way to do it

Any sensible advice greatly appreciated

Get it done professionally.

tjr83, I do not know you, so this is nothing personal, I can only go by the information you have given.

There are several errors in your "plan" which you clearly do not see. (If you could see them, you would not have made them) this makes me believe you are not competent to do the job, so I suggest you get an electrician in, consult him/her let them do the job properly, but YOU offer to do the donkey work. I would not like to find out you or a loved one have been killed because of your error.

I plan to have it all connected by a professional but want to run the cable in myself. I will of course consult them beforehand but like to have an idea in my head first. Be grateful to know what the errors are

The only person you should discuss this with is the spark you find who is willing to sign off your work.

FWIW I never sign off DIY work or register it for Part P

20 meters and hot tub may need a TT installion. It is not simple.

So electrician has been out and suggested 6mm cable to shed, approx 30metres then 4mm from shed consumer unit to hot tub. Does that sound sufficient?

I've done a reasonable amount of DIY in my time.
Plumbing = YES
Electrical = Yes, if it's relatively straightforward.

[Water and 220V] = NEVER

Nobody can really comment …..
