Hiya,
Thanks again for the replies and I greatly respect everything you say about mains electricity, however it is for my University major project and I also have a great deal of common sense, plus always do full research on my devices before plugging it in.
On that note, does anybody believe I should have a diode in this type of set-up, if so what type?
Thanks for explaining the diagram as it now makes a great deal more sense.
Cheers!
