Maximum GPU load is which value?

Maximum GPU load is which value?

• A. 1000 A
• B. 1500 A
• C. 2000 A
• D. 500 A

Answer: (B)

When you hear “maximum GPU load” in this context, focus on the limit of current that the Ground Power Unit (GPU) connection to the aircraft is designed to deliver without overloading the aircraft’s electrical system. The GPU is used on the ground to power the airplane’s electrical buses, start systems, and climate control, so there is a defined upper bound on how much current the aircraft can safely draw from the GPU. That upper bound is set by the aircraft’s electrical architecture—the receptacle, wiring, bus bars, and protective devices are all designed to handle up to a specific current. The correct choice is the value that matches that published maximum. Any lower value would not provide enough current to support peak ground operations (think of simultaneous avionics, air conditioning, lighting, and other loads). Any higher value would exceed what the system is built to tolerate and could trip protections or cause damage. So, the best answer is the option that aligns with the aircraft’s official maximum GPU current rating, because it accurately reflects the highest safe power the ground support can push into the airplane without compromising safety or performance.
