What is the total kVA load when a 240-volt 15 kW load and a 120-volt 10 kW load are connected simultaneously?

To find the total kVA load when both the 240-volt 15 kW load and the 120-volt 10 kW load are connected simultaneously, it's essential to convert the kW ratings to kVA first. This conversion takes into account the power factor, which is typically 1 for resistive loads (such as heaters), but may not be true for other types of loads, such as inductive.

First, for the 240-volt load:

• The formula to convert kW to kVA is kVA = kW / Power Factor. Assuming a power factor of 1, we get:

[

15 \text{ kW} / 1 = 15 \text{ kVA}

]

Next, for the 120-volt load:

• Again assuming a power factor of 1,

[

10 \text{ kW} / 1 = 10 \text{ kVA}

]

To find the total kVA load, simply sum the kVA of both loads:

[

15 \text{ kVA} + 10 \text{ kVA} = 25 \text{ kVA
