Thanks for posting the picture.The top photo is that of my appliance, the second photo is the transformer
Yes, but I am asking about the input to this transformer, do you just spin some stripped wire on it and then screw it down? Seems like it should be more isolated than that.
I know how to wire the 220 side, I am asking about the 110V side.

That's exactly what I was thinking, one would think there would be a box that seals all of this internally. Perhaps I will make something similar to shield it better.If there is any isolation going such as with either a SMPS or a linear transformer, you want to ensure that the earth (ground) is re-referenced to the secondary side, the ground will do you no good if it is connected/sourced from the supply power and is not re-referenced to the secondary side.
A test first with a meter from secondary live to ground should read full AC secondary voltage, if this reads OK confirm it with a load such as a incandescent lamp.
It seems quite dangerous to have exposed terminals on the outside??
Max.
It would NOT be ok in the UK!It seems strange to use binding posts (the reason for my question about it's function) for AC input but I guess that's OK outside the USA.
You can run it direct off of a N.A. 240v supply, no neutral needed or used, just L1,L2 and GND.At a second glance I wonder if I could skip the transformer and wire this using two 110V lines as my power and neutral and then just ground.
