House 3 phase really needed?

[sam423]

Hi guys


My 3 phase mains supply cable needs rplacing as its burnt out and very old.
My question is do i really need to use 4 cables again as nothing in the house is 3 phase and the load is not split?


There are 4 cables going into the top of the ' rcd' switch but only 2 coming out of the bottom to supply my lights and socket switches.


Any help appreciated


Thanks

1. Is this installation in Spain, and if so, how many amps per phase? 2. What do the other two phases do, as they are connected to load terminals of main switch?

HiYes it's in SpainHow can I tell how many amps there are per phase? I know there's 110v eachThe 4 cables go into the top of the main switch then out of the bottom into top of ,rcd' switch but then only 2 cables come out of the bottom of the 'rcd'.

There are no other cables. Only 2 come out of the bottom of the 'rcd'.
