Looks like I bought a Stainless steel box took the back off and checked everything no moisture all connections are tight still trips breaker as soon as the heating element kicks in, element shows to be good and it does start to heat before it kicks the breaker, I did hook it up to my generator and it showed it was pulling 800 watts before it kicked out. Maybe a bad controller, I may just see if I can get some of my money back and call it a day.
