Multiple Conductor Correction Factorsĭisclaimer: The information shown here has been assembled from sources believed to be reliable, but is not guaranteed by Cooner Wire Co. Multiply the ampacity rating from above by the correction factor listed below to determine the ampacity rating of a conductor in a multi-conductor cable. Let us know what you thought of our guide and if you found it helpful, share it for others to discover.Lead Wire Current Carrying Capacity (Ampacity) AWG SIZE It can also be useful to keep in mind that the size of the circuit breaker should be enough to handle the amps of your motor. Remember that the awg rating of the wire will possibly change depending on the length of wire that you need and you will likely need a thicker, lower gauge wire the more powerful your motor is. Now that you know a little more about what some of the technical terms mean you should hopefully find it easier to work out the size of wire that you need for your trolling motor set-up. Wire Gauge And Circuit Breaker Size Guide But we have put together a table with the amperage rating of common trolling motor sizes for kayaks so that you can get a better idea of the size of wire to use based on the length you need, as well as the recommended size of circuit breaker. Your trolling motor manufacturer should recommend the ideal awg size to use with your particular trolling motor. For example, if you need a longer length of wire, you’ll likely need a lower gauge and therefore thicker wire. Many trolling motors can be used with 8 gauge wire, however, the length of wire you need and the amperage of your motor can alter the size of wire you need. > How long do batteries last? What Is The Best Gauge Wire For 12-Volt And 24-Volt Trolling Motor Batteries? Generally, your circuit breaker should have a higher amperage rating than your motor so that it’s able to sufficiently handle the level of current that is passing through it.įor most kayak trolling motors you’ll probably need either a 50 amp or 60 amp circuit breaker, depending on the amperage draw and voltage of your motor. The circuit breaker effectively stops the power if the level of current is too high.Ī circuit breaker is required for many trolling motors as the US Coast Guard regulations state that you must have a circuit breaker or fuse installed to protect any ungrounded current-carrying conductor. Cable sizing is fairly simple it is a function of the length of a cable measuring from the power source to the appliance, and the current (amperage) that. BreakersĪ circuit breaker helps to protect the electrical circuit from damage due to an overload of current. This is unlike AC (Alternating Current) that we find in our homes via the power outlets in the walls. This is generally known as DC (Direct Current) as the current is flowing in a straight line directly from the battery to the motor. Voltage is basically the current that’s flowing from your battery to the motor. With a 24 volt motor, you will need two 12 volt batteries. With a 12 volt motor, you’ll need one 12 volt battery. Most trolling motors for kayaks will be either 12 volt or 24 volt. The volts that your trolling motor uses will usually help you to determine the size of wire gauge and circuit breaker to use. You can calculate this by dividing the pound thrust by the voltage and multiplying that by 12. The pound thrust rating of your trolling motor can be used to work out how many amps it draws. The amps that your motor draws can be used to determine the size of circuit breaker you will need for your system. The amperage draw of your trolling motor is how much power or current it draws from your battery. > How to wire a trolling motor battery Amperage Usually when you’re choosing your wire, the longer it is in length, the lower awg rating you’ll need, as you’ll need the wire to be thick enough to compensate for the extra length. The larger or thicker the wire, the lower the AWG number. One circular mil refers to the diameter of a circle, with the cross sectional area of a wire being equal to its diameter squared (circular mil area). Wire gauge, or AWG (American Wire Gauge), is a term used to refer to the area of the cross section of a round wire and relates to the circular mil area.
