The number of amperes drawn by the load is to be obtained from the manufacturer of the equipment. For motors, the current must be obtained from tables 430-148 (single-phase) and 430-150 (3-phase) of the NEC. Care must be taken to follow the guidelines of the NEC with regard to the number plugged into the calculator.
The table above applies to the single phase systems, in steel conduit, at a conductor operating temperature of 75°C. It assumes a power factor of one. The table may be used for systems using non-steel conduit, but actual results for these conditions may result in a greater voltage drop. ENCORE WIR. CORPORATION.

19 May 2010 Quality marine wire, as specified by ABYC standards, will always be stranded rather than solid, and always tin-plated copper. In addition, the DC Wire Selection Chart shown below assumes a wire insulation rating of 105°C. A lower rating will decrease the current-carrying capacity of the wire. To use the
