RCD help

[Ilovetosparky]

So I put in a new CU 6 circuits but 2 of them had to be seperate from the rcd. So i turned my board into a split board but with the same neutral bar, i have a socket circuit on the main switch and one on the rcd side. Whenever i plug anything in the RCD trips, when i tested the cables the reading were 999Mohms. Will using the same neutral bar cause the rcd to trip?

If you have a split board with a common neutral busbar, it will trip.

You need each RCD to have its own neutral bar.

Or, better still, fit RCBOs.

All socket outlets require RCD protection

Will using the same neutral bar cause the rcd to trip?

Yes. Every time.

Why are you installing a consumer unit when you clearly have no idea what you are doing?

 

[AndyPRK]

you need to ensure your socket circuit neutral wires return to the correct neutral bar.
One bar for RCD, one for non RCD

What 2 circuits are not RCD protected? lights and sockets or ?


If still stuck, take a picture and I'm sure someone will spot the fault

Of course it will, you obviously fail to understand how and RCD i designed to work...

They trip on the difference they sense between the current passing through them, comparing the L to the N current. Any difference greater than the designed trip current, causes them to trip, based upon the current finding an alternative route to earth - possibly via you or your family.

In your case, the alternative route is via a commoned neutral bar.

What is the problem with having them all rcd ?

 

[EFLImpudence]

i have a socket circuit on the main switch and one on the rcd side.

Hopefully the RCD circuits are on the Main Switch 'side' as well.

I think it is a troll, no one is that daft.

You may be right - but you should never underestimate the capacity of people for being daft

Kind Regards, John

It is amazing how ignorant ( lack of knowledge, not stupidity ) some people can be when it comes to DIY electrical work.

They see a person putting wires into holes ( terminals ) and tightening the screw without realising that these are not random connections.
