That will give you an estimate of load used by w/v=amps. Of course me new items can added to circuits.

Rcd works by earth leakage, rcbo are more intense and have live and neutral connected to them working similar to an individual rcd, allowing circuits to be used without tripping out an rcd.


It will not give you an estimate of the load. If I decided to power everything up at once in my house then I would blow the main incoming fuse. You have to allow for diversity.

BTW an RCD does not operate by earth leakage but by detecting an imbalance in the live and neutral conductors. Of course earth leakage will trip one but that is not how they work.

And of course an RCBO operates in a similar way to an RCD. That's because a RCBO is a RCD (with overload protection on it).

Maybe you underestimate my knowledge of electronics and electrical stop trying to insult me I am aware of imbalance across neutral and live across coil which activates trip. If I was to ask to you how a transistor works you would have to search the Internet for an answer, I don't need to have knowledge of components inside of the mcb and rcds and their functional purpose.

As for diversity am aware a diversity factor is allowed that why I said I will calculate load for you

He's not trying to insult you.

I'm no Electrician however OnlyMe is.

as for you multiman I reserve judgement.

Please play nicely both of you. :thumbleft:

I would not have to look up transistors on the internet. I spent nearly a year at University studying electronic engineering before I was was asked to leave for engaging in illegal activities.

I don't need to have a knowledge of components inside an internal combustion engine to know how to drive a car. But at least I would know if it was a petrol or diesel car and therefore I know what fuel to put into it to make it work.

It is good practice to add the flylead/earth tail - and I am sure all the sparks here would agree with me.

Although the socket screws will provide the required earth for the backbox, for the few minutes it takes to do the job properly then it's a no brainer.
