737NG只有ground service power; 744等有货舱装载系统的才区分ground handling power和ground service power.The ac GSB is powered by ac bus 1, APU generator No. 1, or external power No. 1 through the ground service select relays (GSSRs) and the ground service transfer relays (GSTRs).
The ac GSB provides 115 volt ac power to such loads as interior lights, passenger lavatory loads, and battery chargers.
The ac GHB is powered by external power No. 1 or APU generator No. 1 through the ground handling relays (GHRs). The GHB supplies power to such loads as cargo handling which are powered only on the ground.
