Question

The total load on a certain service is 525 kVA. One-third of this load is from motors; 3/5 is lighting; and 1/15 is from other loads. What is the kVA of each of these breakdowns of loads? Match with the correct answer shown below.

Answer 1

Answer:

Motors 175 kVA

Lighting 315 kVA

Other loads 35 kVA

Step-by-step explanation:

The total load on a certain service is 525 kVA.

One-third of this load is from motors, then

$\dfrac{1}{3}\cdot 525=175\ kVA$

is from motors.

$\frac{3}{5}$ is lighting, then

$\dfrac{3}{5}\cdot 525=3\cdot 105=315\ kVA$

is lighting.

$\frac{1}{15}$ is from other loads, then

$\dfrac{1}{15}\cdot 525=35\ kVA$

is from other loads.
