Choosing a power supply, switch fuse size

You really shouldn't be undertaking the work if you're not confident in your own knowledge and competence because if something goes wrong you're responsible and you will have to justify everything and every decision you've made from the design, installation and testing. Asking here gives you no cover should YOU cock something up.

I'm sure there are times when you are not sure about things right?
Usually these coldstores are straight forward to wire and I have no problem with them. Sometimes we get the odd job and I can't say to my boss that I'm not doing it...
Do you think my guess on the breakers is not right?

If I'm unsure of anything I refer back to the relevant legislation I don't go on forums with a vague outline of proposed works to seek confirmation. You should have all the correct design and cable calcs for the installation and that should provide you with all the info you need. If you don't.....Well what are you playing at

I have no choice and I have to do the job.
Unfortunately I don't know as much as you about the trade but it is what it is... I can't change that.

I don't think my choice of breakers is far from what it should be, you still haven't express an opinion about that.
If you have no intention of helping, you don't have to keep replying otherwise we will be both wasting our time to get anywhere.

Thanks for your comments so far

My employer says that the sockets are for general use and to go with the maximum rating to cover ourselves. There are from 4 to 8 in each room. 6 circuits, 6no 20 amp RCBOs?

So are you going with the 'maximum rating' or 20A??

I might wire the ones with 8 sockets as a ring

Either a Ring Main (it's Friday and that's going to annoy quite a few people) or a Radial.

Yes spoon, they are wired with 2.5 pvc single and I always thought that would be the maximum rating, do you think I'm wrong?
I have wired those rooms with two feeds. The plan is to have two circuits with 4 socket or a ring of 8

Thanks

Yes Dillb, I'm quite serious.... Did I write something completely stupid?

You cannot be guessing the circuit design and then ask people on a forum who have no knowledge of the site to confirm your guesses are correct.
