Looks to me like you connect your mains to the lower terminals (where it says 240v) and that your lower voltage output (selectable via the rotary switch) is connected to the upper terminals (where it says 1 to 1.8v). The size of cables will depend on how much current you plan to draw - i.e. how heavy is the load?

You don't need colour codes, connect live & neutral to the lower terminals, either way round, and I'd also connect the earth wire to one of the screws, the bottom LH one seems to have a tag there already.
Again if the output is AC you connect those terminals to the AC connections on your rectifier, either way round, it doesn't matter.
For the full 50 amps you'd be looking at 6mm^2 cable.

Hi Graham, that much I had deduced but the wires are not colour coded, so which is which, the available loads are shown in the pic. Need a sparky on this one, thanks anyway.

Worrying!
If it is AC and only 1-1.8V, then adding a diode will drop about 0.7v and only give half wave out. A full wave bridge will drop 1.4V so near nothing left either way.
you will nee Shotkey diodes that are a bit better with 0.5V drop
