What is the maximum GPU load in amps?

• A. 1000A
• B. 2000A
• C. 1500A
• D. 2500A

Answer: (C)

When you connect external power to an aircraft, the electrical system has a defined maximum current it can safely accept from that source. The Ground Power Unit can deliver current up to the bus and protective-device limits without causing voltage drop, wiring overheating, or tripping breakers, so the load from the GPU must stay within that rating. In this case, the system is rated for a maximum of 1,500 amps. That means you can draw up to 1,500 A from the GPU without risking overload, while any higher value would exceed the bus capacity and could cause protection to trip or components to be stressed. The other numbers either stay below the true maximum or exceed it, which is why 1,500 A is the correct maximum.
