Since I'm working on my shop and I have capacity in my main panel, I ran a 100A sub-panel to the shop. I used 3 wire (2 hots and a neutral) and a ground to run them. From the X200 docs, I sized for 30A 220 VAC circuit for the VFD.
How do I run this into the X200? I initially bought three-prong 220V@30A turnlock outlets and plugs - Now I'm second guessing myself. Do I need four-prong?
