Post electrical diagram for bilge dc breaker panel

I am adding a automatic battery charger then to a battery switch 3 pole for 2 batteries,then to a new water tight dc distribution box,1-50 amp, 2-5 amp,1-3 amp,the 50 feeds forward and then comes back to feed the 5 and 3 amp breakers,for the bilge pumps and the blower,I think ? Can someone please help me on this. A diagram and wire sizes here is a picture of the old one

You're basically saying you're gonna go feed a bus bar or fuse block with the 50a then from that bus/fuse come back and feed the smaller 5a and 3a loads.

For the 50A load I'd say #6 is more than adequate. For the 5A(I assume your bilge pumps) I would run them with #12 and over fuse it to 15A. You're better off having the bilge pump keep running if there's a short than the breaker trip because it's fused for the rating of the pumps. Especially if the boat is going to be slip kept. As for the 3A load run #16, my blower is powered by an #18 because it only goes maybe 4' from the helm down. Keep in mind the ampacity of the wiring or cable assembly you're gonna use is also negatively affected by heat from being in the engine compartment/bilge compared to outside.

Also ancor has a ton of useful resources when it comes to wiring.

I'm up around jersey City area with a 30' Albemarle. If you were a little less of a drive id have no problem coming down to give you a hand with the work but with doing 6 days a week at work the little free time I have on Sunday and Monday mornings doesn't leave much wiggle room. Keep fighting the good fight though!

No you didn't post anything since you need at least 10 posts before you can upload pictures.
