Total generator power for the described loads is approximately?

• A. 450 W
• B. 385 W
• C. 402 W
• D. 500 W

Answer: (A)

The main idea is to size the generator by adding up the real power each load requires. For AC devices you work in watts (not VA), so take each load’s running wattage and sum them to get the total power you need the generator to supply. If any load is given in volt-amperes, multiply by its power factor to convert to watts. For motors or devices with a strong startup surge, you’d add a surge allowance, but for an approximate total you can use the running watts and include a small margin.

When you add the described loads, the total comes out to about 450 watts. That makes a generator around 450 watts sufficient for the demand, which is why this choice is the best approximate match. The other options are notably lower or higher than the summed running watts, so they don’t align with the actual load requirement.
