    Understanding three phase.

    So, my OP was a genuine question. What is it that people struggle with? Or is it something that I don't know about?

    Which switch for a pond pump?

    The Blagdon switches as above are very expensive, B&Q sell something similar but much cheaper in their larger stores, it shoulda be on their website.

The line will go to the in-line fuse then the power switch then split into the separate switches then to each thermostat. out...

    2391

    IMO 2391-10 and 2391-20 should be requirements before calling yourself an electrician. 2330 level 3 starts on design but doesn't go into it too much.
