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??
