Why is it important to know a facility's power requirements?

• A. Generators must be capable of supporting the required load without being oversized or undersized
• B. It helps select the right fuel type
• C. It reduces maintenance requirements
• D. It shortens install time

Answer: (A)

Knowing a facility’s power requirements lets you size the generator correctly. The generator must be able to supply the required load, including any startup surges from motors and other equipment, without being too small or unnecessarily large. If it’s undersized, it won’t meet demand during outages, causing voltage drops, trips, or the inability to run critical loads. If it’s oversized, you incur unnecessary capital cost, higher fuel use, and more maintenance without added benefit. Proper sizing ensures reliable operation, protects equipment, and supports smooth transfer to backup power. Fuel type, maintenance, or installation time may be affected by sizing, but the primary reason for knowing the requirements is to match capacity to the actual load.
