I have a fitted a new consumer unit with an RCD to supply an electric shower. Trouble is it came with no wiring instructions and it looks different from your regular c.unit. It seems there are only 3 terminals to fit 4 wires (+ and - from meter, + and - to shower). Any suggestions? I don't want to get this wrong.

err
how do you mean there are only three terminals? is this an RCD main switch or an RCBO (combined MCB and RCD)?
