Two threads of near identical topic merged.  Please do not start a new thread each day when you already have a very similar topic already on the go.

Two members of near identical name and posting questions on near identical topics merged.  One thread and one member name should be quite sufficient for our other members to find and reply to your questions thank you.

You get what the DNO say don't you?

 

Buy what you think you need depends a LOT on how you heat the rooms and hot water etc.

A proper electrician should be able to tell you that......

If you calculate your total loads allowing for diversity that should give you expected max consumption and thus incomer required. Alternatively see what the DNO give you. Or are you filing out an application for a new supply and you are asked to state your max load?

Easiest way to calculate max demand with diversity, eg do you add showers and equipment using power for short amount of time? Thank you

What's the best way to work out max demand and divercity

Eg do I included a shower as its only running for a matter of minutes

Thanks

Do you think that an electric shower running at 40 odd Amps has much of an effect on MAXIMUM demand?

What I'm asking obviously you will not be adding everything together as that would be 100%. Just trying to find out the easiest way to see what kind of cable I will need to supply the flats

What is the incoming supply available? Does it need upgrading?

 

So many questions... so little detail

Perhaps you can give us some information as to what you think you should be doing to calculate demand and therefore cable size, it would give you more confidence in your abilities if what you show us is not too far off the mark, you will therefore perhaps gain some valuable knowledge thus experience to make you a better spark. :)

Hi I'm wiring a flat with

1 x lighting

2 x ring

2 x heating ring

1 x hob

1x oven

Just would like to know if you would dual rcd the board or use 1 rcd. Thanks

RCBOs - worth the little extra

 

Dual RCD is minimum requirement to meet todays regs

seeing as you have 2 ring rings the a dual arseedee may be just the ticket ;)

Although as above RCBO's would be the best solution.

I would NEVER use a dual RCD board

T,he regs say ccts to be designed to minimise inconvenience/disruption.....2 RCDs does NOT minimise inconvenience, it merely halves it

RCBOs all the way for me...end of

Clifford ,  one arseedee doesn't really comply with the "Inconvenience" factor when tripping .

As the Kerch says  , arseybeehoes are the better option .     I use dual boards  because my loop tester knocks them out but not the "proper" arseydees .
