Personally, wires thinner than AWG20 are too thin to be used in anything except special electric and electronic projects.įor more information about wires and conduits, feel free to check the following articles: Note: Ampacities are given for enclosed wires ambient temperatures. Note: the great thing about Ampacity is that it has the same value, regardless of the voltage applied - generally, it "just" depends on the wire thickness, wire material, and quality of insulation (allowed maximum temperature).Īnd here is the Ampacity chart of enclosed copper wires: Ampacity of the wires is given in Amps - Ampacity is the current-carrying capacity of the wires and is s usually defined as the maximum current that a wire can carry continuously under the conditions of use without exceeding its temperature rating.Area in 2: cross-section area of the cable, given in inch 2.Area mm 2: cross-section area of the cable, given in mm 2.Diameter inches: diameter of the cable, given in inches.So, if you need, for example, AWG 5 cable, but you are offered cables in millimeters only, you should buy a cable 4.62 mm in diameter (with a 16.77 mm 2 cross-section area) or next thicker cable. Diameter mm: diameter of the cable, given in millimeters.AWG #: American Wire Gauge cable thickness.Keep in mind that metal resistance increases with temperature, not by much, but if you can't hold your trolling motor cables in your hands due to the heat, decrease the power and get thicker cables as soon as possible. Other materials can be used as well, but most of the time, wires are made out of these materials. Some of the most commonly used materials for wires are copper, with a resistivity of pure copper of 16.78 nΩm at 20☌ and aluminum, with a resistivity of pure aluminum of 26.5 nΩm at 20☌.

With various standards around, it is important to know how to convert proper cable sizes from one standard to another.Īlso, voltage drop and power losses depend on the cable length, thickness, and current flowing through the cable. See our Marine Wire Size and Ampacity chart behind the West Advisor tab, to select the right wire for your job.Wire Gauge Charts: AWG to mm2 Conversion Charts and Wire Sizes These duplex wires are available in 6-20 AWG to meet the demands of a variety of circuits. Because this cable is rated for 75☌ (167☏), meets USCG and ABYC standards required to be run through engine rooms. The exclusive vinyl insulation protects the wire from saltwater, oil, battery acid, gasoline, and UV damage while remaining flexible in temperatures down to 40☌ (40☏).
The flat cover is easy to write on to keep track of circuits on larger jobs.Īll of Ancor’s wire is thin stranded tinned copper to offer the most flexible, corrosion and vibration resistant wire available. Ancor designed its marine grade duplex wire specifically for marine use and conveniently packs two individually insulated conductors into a single flat cover to help speed up the wiring process. Using the right wire for the job will reduce the time spent fishing it through your boat and give you the confidence it won’t let you down. Run two conductors at once with duplex wire designed specifically for the marine environment
