@Neale,

That's a great deal of information and something I am going to have to digest.
I am not an electrical engineer at all, my background is mechanical engineering.
But with an enquiring mind and some help from people on here I hope to be able to build a decent control panel.
My biggest concern it that if wired wrong then it could "KILL" me or at the very least cause some damage.
I can follow wiring diagrams etc and work through things (Other hobby is OO gauge model railway).
So I was hoping that someone maybe would be able to help out with a schematic or something to point in the right direction, so I do not make the good lady a widow!
