28VDC Ground Power Unit
Unitron Power Systems and FoxCart 28VDC ground power supply units provide continuous output power for your aircraft from a wide-range of power input levels and can run from 50 or 60Hz sources. The units are available in lightweight mobile or fixed configurations, suitable for either hangar or ramp use. Unitron’s 28VDC GPUs are also used in the design of electrical distribution systems for large civilian and military ships to supply power to the helicopter deck.
NEC 18" Rule: There is the well known “18in rule” that requires there be no electrical connection allowed within the 18in area above the hangar floor known as a Class 1, Division 2 area. This area is considered hazardous because fumes from spilled jet fuel may not have yet dispersed sufficiently to avoid ignition were an arch to occur; in this context, from a loose electrical connection within a mobile power unit (GPU or cart). For a more thorough explanation of this ruling, one can reference Article 513 of the NEC and IEC 60079-10-1 of the European Standard as well as the article available in the below downloads.
