My device is 30amp 220v and I tried using it on the 30amp side of the pedestal and it would power on but non-functional so no bueno. What do I need to plug it into the 50amp side and take advantage of the 2 hots legs so my device will work? I'm confused with adapters because I read that a 50amp to 30amp adapter doesn't have the 2 hots so the 30amp is still only 110v. Is there such a thing?
