Hi Mio

I would count how many MCB syou require. Also Duel RCDs and add a couple on for spares. You will need to Know what you are usiing at themoment . You can position the MCBs and RCDs to suit your system |MIne is very similar to this one http://www.ebay.co.uk/itm/WYLEX-15-WAY-DUAL-RCD-INSULATED-CONSUMER-UNIT-C-W-MCBS-/110748949814?pt=UK_BOI_CircuitBreakers_RL&hash=item19c926dd36 . But set up differentlty. ie Main RCD(80A) has Houshold 7 MCBs+ 1 spare. 2nd RCD(63A) has 2 MCB Has outside lights + garage door on 16A MCB and Pond on 32A MCB. Hope this helps.

Best REgards Dave

That looks the same however the configuration might be different. ie you might need different RCD and MCB depending upon what you need. Mine is this

Starting from the right

Main Breaker 125 A

RCD switch 80 A

Followed by MCBs lights 10A, Hob 32 A,Sockets 32A, Shower 32A,garage 16A,Central Hteaing 10A, Solar PV 16 A, Followed by second RCD then MCBs

Outside lights 16 A, Pond 20 A.

Installationj especially with heavy cables can be tricky and should be carried out by a qualified professional.

Hope this helps

I have from left to right 5A 30A 30A 15A 30A 15A .... Translate that into MCB`S for me please Dave Very Happy


This is an ancient fuse board but the Kitchen supply has been separated and fitted with RCD`s when it was all rewired.

I think you will be ok with 6A, 32 A, 32 A, 16A,16A , 32A and !6A. together with 25 or 32 A for pond on other RCD depending upon what you want to run of this.Check with the supplier that it comes with these MCBs . Also you could go for the same main MCB as me 125A Best regards Dave

Mio a 10kw heater will take 43 amps so will require a 50 A MCB and one of the 80 A RCDs. You will probably have to put the 10 Kw heater on a seperate supply than the other pond equipment. I would also go for a higher mains breaker than 100A with the 10kw heater. Especially if you have an electric shower and electric cooker. Your electrictian friend will be able to see exactly what you have got and will need to do the job. Good luck dave

I was going to go ahead and buy it Dave prior to having it installed so need advice on what to have it include upon purchase ...

Hope i`m not frying your engineering brain cells here Sweetie ... but in terms of watts/kw ? how big a heater could be safely run on this particular 100 amp consumer unit safely iyho ?

Mio

You should already have a main fuse fitted in your fuse box which will give you an idea of what you need at the moment. Without any very large heaters such as 10 Kw

It all depends upon what else you are using. ie If you are using a 10 kw heater & a 10 kw shower you could potentially use 2X 43 A which is 86A then add in electrical hob say 4 A, electric fire 13 A and every thing else and you could be over your 100 A. However if you were to drop your heater to say 6 Kw and your shower is only 8 or 9 Kw and no electric fire then you should be OK with the 100A main breaker.

How much more would it cst to replace the breaker with a 125A. just to be sure?

I was going to plumb a 3KW heater into the WLP too Dave and the Cooker is electric also Rolling Eyes and I would like the option of buying a bigger heater later on ... not to mention needing a spare for the QT.

The Wylex 100 amp mains breaker is factory fitted ... do you mean have an electrician simply remove it from the board and fit a bigger one like these ? http://www.tlc-direct.co.uk/Main_Index/Consumer_Units_Index/index.html?source=adwords&kw=MCB&gclid=COeVjbi4uqsCFYIMfAodGRfCdg or buy a consumer unit with one already fitted...

I strongly advise you to contact your electrical friend and show him exactly what you want to do. because there is also cable lenths to consider. He will be able to advise accordingly and buy seperately what you need from somewhere local . This will save any confusion and or buying anything which is not needed. I only gave advice as to gain knowledge. I would be quite happy to carry this workout myself, on my own house . If I could actually see the full installation. Now with your new found knowledge you will be able to discuss what is needed and not be ripped off.Sorry if qI am unable to help further.

Best Regards dDave

In most peoples cases I would say yes but for folks such as us who have I than normal needs. I can only repeat what I said previously and suggest you get your electrician friend to advise you after seeing the installation you already have first hand. Sorry if I can,t be more specific

Good luck with it I am sure you will get there in the end

Good Idea ...

The Plasterer will be here thursday Dave ... who is the `Electricians` cousin Very Happy I will ask him to get him to take a look at the proposed Wylex or ask him to fashion a more apt one himself Very Happy

The Wylex is twice the size the old Consumer Unit was Dave so will need relocating .... Very Happy

Looks like a good piece of kit though ... I chose 6/10/16/20/32/40/50 AMPS which the Electrician advised Very Happy

The pond will run on the 50 Amps on a separate RCD ...

Don`t you just love progress Sweetie Very Happy
