[SOLVED] Transformer Question.

[kb jones]

I would like to know how these types of transformers are connected. It only has 3 wires on it (no primary or secondary like conventional transformers) with the inscription under each wire 0v 220v 240v
I am feeding an input of 240v and require an output of 220v.

 

[ashokok]

connect input to 0V and 240V
connect output to 0V and 220V

Thanks ashokok,

Just to clarify that; Do you mean Connect the live wire to 240V wire on the transformer, neutral to 0v. Then take neutral out of to 0v and live output from the 220V?
