Total Load Calculation: Reflecting on Power Consumption

How do we calculate the total load for multiple motors with varying power ratings?

Given the scenario of a feeder serving four 2hp motors, three 5hp motors, one 15hp motor, and one 25 hp motor, all operating at 208V, what is the total load?

Total Load Calculation

The total load for the given motors is 25834 Watts.

Calculating the total load for multiple motors involves determining the power consumption of each motor and summing them up. In this case, we have four 2hp motors, three 5hp motors, one 15hp motor, and one 25hp motor, all operating at 208V.

First, we convert the horsepower (hp) to watts using the conversion factor of 1hp = 746 Watts. This allows us to calculate the power consumed by each motor:

  • Four 2hp motors: Power = 2 hp = 2 × 746 Watts = 1492 Watts
  • Three 5hp motors: Power = 5 hp = 5 × 746 Watts = 3730 Watts
  • One 15hp motor: Power = 15 hp = 15 × 746 Watts = 11190 Watts
  • One 25hp motor: Power = 25 hp = 25 × 746 Watts = 18650 Watts

Once we have calculated the power consumed by each motor, we can sum them up to find the total load:

Total Load = 4 × 1492 Watts + 3 × 3730 Watts + 1 × 11190 Watts + 1 × 18650 Watts = 25834 Watts

Reflecting on this calculation, we see how the total load is influenced by the power ratings of individual motors. Understanding and analyzing power consumption is crucial for efficient energy management.
