Navigate to the recreational boater area, and click on the "become a member" link. Sign up for the free trial membership, and use that five-day window to gain access to the E standard. In E, you'll find a series of tables to help you properly size AC conductors using the criteria outlined here.

The app does a great job of getting you to the standard compliant wire size for both AC and DC installations and, unlike other apps available, will also convert to metric wire sizing for those of you with European-built boats. Keep in mind that the search does not realize that the minimum wire gauge size the U. This applies to both AC and DC circuitry. As already mentioned, we're particularly concerned about voltage drop with DC circuits, so part of the circuit design criteria is determining how long the circuit is.

By that, I mean the distance from the power source to the load or appliance, and back to the source of power. Remember, all wire has inherent electrical resistance, and the longer the run of wire and the smaller the wire, the more resistance will be present.

Also remember that the inherent resistance is less for heavier wire versus thin wire. Voltage drop due to electrical resistance in low-voltage systems can have a dramatic impact on equipment performance. System voltage and amperage make a difference, too. With higher voltages, smaller gauge wire can be used to conduct higher amounts of amperage. This creates a compelling reason to use higher voltages, but that's a story for another day.

The other issue that needs consideration when sizing DC conductors is what level of voltage drop is going to be acceptable for the circuit in question. This is an area that the Coast Guard addresses in its regulations for recreational boats.

Will it operate correctly at that voltage? If not, you'll need a larger wire. These circuits are identified as battery-to-distribution panel primary conductors, navigation lights, critical electronics for communication and navigation, and bilge blower circuits.

It's important to understand that the Coast Guard does not even require bilge pumps, and in the eyes of ABYC, bilge pumps are intended for removing incidental accumulation of water in the bilge from rain, washdown, and the dripping stuffing box on a propeller shaft. Expand each box to reveal background information.
