There’s a particular sound when the shore cord goes in and everything wakes up—chargers humming, fridge cycling, lights steady as a dock post. It feels like you’ve tied the boat into the land, which is exactly what you’ve done.
The trick is remembering that the green wire isn’t just a courtesy; it’s a pathway, and the marina has plenty of opinions about where current wants to go. Most days it behaves. On the wrong day, it eats metal quietly or gets loud in a hurry.
A little discipline at the pedestal and a clear idea of what you’re trying to block versus what you must never interrupt keeps the boat safe, predictable, and easier to sort out when something doesn’t smell right.
