Diagnosed and fixed my first electrical problem...

I have a 2008 343. Last night I noticed that the galley lights wouldn't come on but everything else did. I went through the manual and figured out the easiest thing to try first would be the wago block.

I gently pushed each connector in and sure enough the one that the manual showed feeding these was loose. I popped it back into place and the lights work now.

Now why would this have come lose in the first place? Does this function as a circuit beaker? A couple weeks ago, the panel came open when to boat took a nice gust of wind. Was it more likely that that action loosed the connector?
