Hi all just a quickie, carrying out a inspect&test on a dom property to find 2 Ring FC's 1 of these covers 6 x sockets 2 on the ground floor and 4 on the 1st floor, the 2nd MCB controls the other half of the 1st and 2nd floors! Does this seem strange to any1 else?

The house was built in the 80's and wired in R&B twin. I have seen the landing and hallway sockets wired on the opposite circuit before so that there is a socket incase of a fault. Looking forward to the opinions many thanks

 
I have seen houses where there is a ring covering the front half of the house and another ring covering the rear half. I don't think it's a problem as long as the circuits are clearely marked up on the DB and if a 17th edition dual RCD DB is going in then one ring goes on each side.

Quite common around this neck of the woods - especially on new builds.

 
I think splitting the sockets front and back is a great idea - if you loose a circuit, you don't have to drape extention cables down the stairs.

 
Socket, lights or any circuit for that matter can be wired in whatever arrangement is convenient to the designer, installing contractor or property owner or any other relevant parties. Providing all circuit arrangements are documented and the general guidance for the amount of floor area one circuit covers is followed, then there is no problem at all. Modem solid floor properties are often wired circuits partially upper and lower floors due to the economics of cable used during installation.

Front and back quite a commen way of wiring houses.
And put the FRONT light circuit on the same rcd as the REAR socket circuit.

So if you plug something in that trips the RCD, that room is not plunged into darkness.
