I have a 2hp jbj commercial chiller and I was seeing if anyone could help me in making sure I get it wired correctly. Says it needs 208/230volt power source. I thought I would need a 2 pole breaker and 4 cable wire to install 240 volts. I only see 3 spots on the bottom here to hook up the wires. Any know how this should be hooked up and what I would need? Thanks in advance
