Is there good correlation data between heavy splash, high pressure wash, high humidity, and immersion testing? At the very least, an order of most-to-least stringent. Or are there more variables to consider here?
What's the possibility of water wicking through an 18", 20 ga copper cunductor? If moisture is found in my encapsulated housing with the wire running into it, I'm wondering if I need to also look into the "sealed" connector which houses the wire and terminal.
