Ever see a "Polka Step" painted on a dance floor?
That's what my back looked like after the DW made a midwinter midnight trip to the bathroom.
OK, here's what happens...
Ever try and remove steel spark plugs from a warm aluminum cylinder head?
Stuck tighter than a Bull's ... in .....
Warm bussbar freezes steel set screw.
Aluminum expands greatly around copper wire conductor.
Time after time after time. Causing the TIN coating to migrate
Recommendation
Use a brand new RV for the summer
Before storage tighten the loose buss bar set screws and check every other screw in the box.
After the second season tweak as necessary.
RV's that have heaters loading a breaker for many hundreds of hours should be checked annually.
On receptacle or toggle switches I use flat forked #6 terminals to attach wire to the screws. This positively STOPS problems. The fact that the terminals are TIN coated should not be overlooked. I solder the fork (spade) terminals to the wire.
