I do something similar. You *must* regularly inspect the connections in operation. Even on the server side we had people inspect the connections in the server room (with a really cool thermal photography system). L6-30 is a good solution with #8 or #10 wire but it is like anything else, a *small* imperfection can lead to thermal expansion frequency and it gets worse. I shine a laser thermometer on mine and physically touch the connections. I've never had to retighten them or redo one, but... I'm always vigilant. It needs servicing if it is more than a few degrees warmer than the wire..
