    No offence intended, but from reading your post it is obvious that this is beyond you. Get a qualified electrician to look at it.

    It really all depends on the size of the pump been installed and the cable run involved,id imagine a 2.5 connected through a 20 rcbo would supply most size single phase pumps for this application.

    i agree with 2011 you shouldn't touch this.

    but if you are intent on doing it why are you running it in swa? is it outside? and if so how far away because distance to pump and size of pump are what should be deciding you cable size

    you probably just need an mcb on your rcd side of your board and you would need to spur it at the pump and fuse it down to size or if it is bigger then it sounds you will need to put an isolator on it oh and if you do instal the cable and do the work in your board yourself and wire the pumpthe company that is installing the pump more than likely will not stand over the installation if it fails and they just say an unqualified person touched it
