What is the minimum calculated service load for 6-1500 watt electric clothes washers and 3-4500 watt electric clothes dryers installed in a motel laundromat?

To determine the minimum calculated service load for the appliances mentioned, it's important to calculate the total wattage based on the number of units and their watt ratings.

In this scenario, there are 6 electric clothes washers, each rated at 1500 watts. The total wattage for the washers is calculated as follows:

6 washers x 1500 watts each = 9,000 watts.

Next, for the electric clothes dryers, there are 3 units, each rated at 4500 watts. The total wattage for the dryers is calculated as:

3 dryers x 4500 watts each = 13,500 watts.

When combining these two loads, the total calculated service load for the laundromat is:

9,000 watts (washers) + 13,500 watts (dryers) = 22,500 watts.

This calculation reflects the minimum service load required for these specific appliances operating at their maximum capacity. Thus, selecting 22,500 watts is the correct response as it accurately represents the combined electricity demand for both the washers and dryers in this situation.
