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.
