The wire sizing guide below provides the minimum wire size needed to limit voltage drops to 5% at a given distance in a 12V or 24V system. BOAT SIZE & MOTOR SELECTION . SAE wire sizes are 6 to 12 percent smaller, carry proportionally less current, and have greater resistance; Wires are not run in engine spaces: Maximum current is 15 percent less in engine spaces, which are assumed to be 20°C hotter than non-engine spaces (50°C vs. 30°C). A motor size is based on the stator size (diameter and height).. For example if a motor is sized as 2207, it means that the stator is 22mm in width and has 07mm in stator height. Motor full load amps are taken from motors currently used by Champion. What it means is that the speed at which the motor rotate for every volt applied to the motor, theoretically. It applies to typical DC circuits and to some simple AC circuits (single-phase AC with resistive loads, not motor loads, power factor = 1.0, line reactance negligible).

It also lists the maximum distances you can run various sized wires to service these motors. NEMA means the standards set by “National Electrical Manufacturers Association”, which is comprised of 560 major electrical manufacturers in the United States, primarily consisting of manufacturers of equipment and devices for power generation, transmission, distribution, and power applications. Rated full load current is often abbreviated as ‘FLA” on the nameplate. Selection Tables – Three Phase Motors. The motor wiring is sized to continuously carry the full load and to keep the voltage drop at full load during start-up within a few %. There are several factors that must be considered before determining the proper size wire to select for an application. If you want to limit your losses to 2% simply divide the distance by 2.5. Choosing the right wire size for your DC electrical project is important, since a wire that is too small can overheat and possibly start a fire. The tables are based on motors of approximately 1450rpm of average efficiency and power factor. WEG, the largest industrial electric motor manufacturer in the Americas is pleased to offer its customers our brand new e-Technical Catalog. Motor: Motor Current Charts. The size of wire required for a given task depends on the voltage being used, the amount of amps required and also the distance that power is being transmitted. Common sizes include 14-, 12-, 10-, 8-, 6-, and 2-gauge wire. A motor with a 50% duty cycle must stay off for the same amount of time it has been on. Correct Cable Size Select the correct circuit type. Selecting the right cable size for the motor is an important parameter for the Industry whether it’s during Installation and Commissioning or during running condition. The wire must be rated for the system voltage and it must be able to carry the current. Sponsored Links . BATTERY, WIRING, INSTALL & SELECTION . Circuit Type Step 3. And the maximum breaker size (MOCP) is dictated by the following article from the 2017 NEC.
