When solving voltage drop problems involving motor circuits, what should you not multiply by?

In voltage drop calculations for motor circuits, it is important to recognize the relevant percentages that reflect the starting and running conditions of the motor. Specifically, the 125% multiplier is significant because it accounts for the additional current draw when a motor starts up, as motors typically require more current at startup compared to their normal operational levels.

Using this multiplier ensures that the calculated wire size accounts for both the normal and starting conditions, thereby minimizing the likelihood of excessive voltage drop and potential underperformance of the motor. In contrast, multiplying by 150% or other options does not align with the industry-standard practices for calculating motor circuit loads properly. Therefore, it is critical to use the 125% factor instead of using a different multiplier that may not appropriately represent the operational demands of the motor.
