Stepdown voltage on a single phase 100VA control transformer is from a 380volt primary to a 220volt secondary.
I am fusing both wires on the 380volt primary side. Are the two wires connected to the 220volt secondary considered hot? Do both of the 220volt secondary connections need to be fused?
Also, If my secondary were 120volt I would use red for the fused L1 and white for the neutral. What is a standard color scheme for the wires on the 220volt secondary side?
