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..
