Wire Size

[boater15]

Trying to be simple and consistent, so I was going to use 14 gauge wire from all my accessories (bilge,FF, LED lights,bow-stern light,horn) to a fuse block. Then I was planning on using 8 or 10 from the fuse block to battery on the pos and neg side with an inline on the positive side near the battery. Is the wire size sufficent? By looking at charts, it seems to be just wanted some personal advice. Thanks guys/gals

If you're running each of the components listed on separate circuits I think you'll be fine. And I'm guessing you mean that you're installing a circuit breaker on the 8 gauge pos line near the battery.

16ga would be ample to run the lights, but there's no harm in using larger wire. The disadvantage would be increased cost and it would be harder to pull a bundle of larger wires through a conduit. 8ga is good from the battery to the switch panel. The fuse or circuit breaker needs to be with 7" from the battery as per ABYC wiring standards..
