I have a 3 phase system (machine) that will be connected to a dust collector. The dust collector is a single phase 230V system. I'm looking at transformers to step down voltage. My question is if I buy a single phase transformer to step down the voltage, how safe is it to connect as a single phase from the 3 phase line voltage? And would it just be 2 legs connected, there is no neutral? Dust collector is 230V, 16A, so around 4-5kVA.
