I agree, it sounds mental. I have a family of 5 with loads of high power stuff and never tripped my 60A. I'll research Hager idea then post my loadings, see what you think.
If I can get down to 60A I can consider T&E again, could I put RCD in Hager?

No, T&E submains in flats isnt a good idea, because you then have the issue of discrimination between the sub RCD and the RCD's in the CU. I stand by the 250a DB and SWA being the most cost effective method.

I Echo what Murdoch says, i dont mind helping and giving advice so you know the best course of action to take, a informed customer is never a bad thing. The works proposed isnt particularly difficult and it certainly isnt rocket science, however, it is extremely difficult to do it well!!. and if you do make a cock of it then the kind of total load were talking about normally equates to a big fire.

To summarise: Cut out - Hager 250a DB- 63a sp mcb type c- 6" galv trunking- SWA .........Simples

Just had a look at Hager, looks good and probably not much more than original idea. But I don't understand how it works. Plan is to use it as sub main. So main intake to 12 meters, then out of each meter into sub main before going off to each CU.
Hager looks like single 250A in then 12 60A out.
What am I missing ?

and to look at some of your earlier threads I would say that you have too much focus on keeping the cost down and not on installing the correct solution.

Another ficticuous sparky !

I've tried to ignore your constant nit picking which adds no value to this thread, but your last comment is too much. If you care to research compulsory HMO licensing you will discover it is impossible to get a licence without a certificate.

If you have anything to add to this thread of value please do so, but otherwise please keep your negativity to yourself.

I dont remember meters being mentioned, How are you intending on doing this?, it opens a whole can of worms now. are you having your own meters installed and charging your tenants yourself or are you intending on having prepay meters, if its pre pay then the DNN must install them and their own Ryefield to supply them, and that will be big cost!.

If you are having meters in the switch room then you are back to Ryefield - meter - switch fuse - galv - swa and with all of that you will need a switch room the size of a bedsit for all of that 12 x over

if you are having the meters in the bedsits then the hager solution will work. you can get cu's to go in the bedsits that have meters built into them, so it would be
Cutout - hager - swa - cu with integral meter.

Brilliant. People think sparking is so, so easy! This is one enormous can of worms

No, his name on install, he's got to have the final word. But I will have a big input as you can see. Just to confirm I am not using a one man band but a large company based in Kent with several engineers.
Anyone that has worked with the council knows there is no cutting corners.

Its all very well doing research but you've said your sparky (if he exists) is on holiday. Leave it to the sparky to quote you for a price and then if you're not happy get a couple more in to quote.

If you are not happy with the imput from the members here maybe you should try other forums.

Like i say i dont mind helping with selection of the appropriate equipment best for the application. at the end of the day thats what were here for!, but i stand by my opinion that it would take a half decent spark to make a decent job of it!
