This is my first time installing a transformer of this type. I know I have to bond my XO in your most common 480 delta stepped down to 120/208 wye but not sure about if I have to bond what is the X3 (or X4, they’re connected) terminal which is where my neutral is landing. Again, this is a 480 SINGLE phase primary stepping down to SINGLE phase 120/240. Please help! Thanks!
