What is the total kVA of three-phase loads of 16, 42, and 75 amps fed from a 208-volt panel?

To find the total kVA of three-phase loads, you can use the formula:

[ \text{kVA} = \frac{\sqrt{3} \times \text{Voltage} \times \text{Current}}{1000} ]

In this case, the voltage is 208 volts, and the currents for the three loads are 16 amps, 42 amps, and 75 amps. Perform the calculation for each load first:

1. For the 16 amp load:

[ \text{kVA}_{16} = \frac{\sqrt{3} \times 208 \times 16}{1000} ]

2. For the 42 amp load:

[ \text{kVA}_{42} = \frac{\sqrt{3} \times 208 \times 42}{1000} ]

3. For the 75 amp load:

[ \text{kVA}_{75} = \frac{\sqrt{3} \times 208 \times 75}{1000} ]

Now, calculate each of these values:

• For the 16 amp load:

[ \text{Approximately } \frac{1.732 \times 208 \times 16}{1000} =
