Hi All. We are tucked away in a new berth for a couple months and we only have 50amp at the dock. And the power is 208v. The Charles Iso Transformer is boosting it to 210-220 but that's it. We are tripping the pedestal at the dock way too much and the boat's service batteries are getting hammered. I've never used a 'bahamas box' before. I picked one up at sailor man that was "bench tested". Is this box good? Is using such a box always problematic? What can I look for? Suggestions?
