    If I connect a L & N to RCD/RCBO but connect nothing on the load side will they trip if I press the test button?

    It will, if you connect phase and N to either side.

    LOL, you were both wrong, while there was a loose neutral, but the actual problem was a dodgy RCBO!

    Rcbo was fine.... Was loose neutral, hence why I said this happen a lot

    We could make up an example, independent of the thread here, but similar circumstances, as an RCD with a loose connection to it also. Shower is not working.

    RCD is replaced, now the shower works perfectly. Was the RCD faulty in this made up example?

    I would examine failed RCD/RCBO for any signs of heat damage, if none connect via a 13A plug and cable and close the switch, press test button, if it operates, connect say electric kettle (full of water) to load end which will give some loading of 8/10A then repeat test with loaded RCD. While the above doesn't prove that the RCD will operate at ~ 40A, it will give some indication, but would not re use it if RCBO because of doubt that it will trip in o/load/short circuit conditions.

    But this ignores that I first fixed the loose connection, but the issue still occurred...

    In your example there is no way to know as not enough testing was done.

    If you still have the RCD can you carry out a test like I suggested avove or just connect up a supply and see if it trips and has continuity through both neutral and live.

    It was a point in general.
