My new blue seas flashy panel came with a 30amp dual breaker, which is pretty standard. I decided I wanted to have more safety than that though, so bought an ELCI. This device is like a GFCI for your whole boat – as soon as it detects a leak to ground, it disconnects the whole breaker – both saving me (if I was touching something I shouldn’t), and also anyone swimming near the boat.
Here is the front of the standard panel
After an hour or so studying the wiring diagram, and the instructions, I managed to get the thing installed. It was a bit of a tight squeeze, since I had to pass both load wires through a little plastic circle (current sensor), but after a bunch of fiddling I finally got it.
Here is the back with it installed
And the front
As you can see, it takes up three slots, instead of the old breakers two, so I had to move the topmost 15amp breaker down a slot.
And here is the finished thing, with the circuit diagram. All connections were made with heatshrink connectors, like all my connections I’ve been doing.
