Electric fire is a most potential cause of fire in space. Short circuit in wire harness is a main initiation way of electric fire. This paper aims to research the ignition phenomena when excess electric current is supplied to insulated wire and make a map for wire ignitable condition. As a result, ignition limit shifts to lower current condition with more higher oxygen concentration and with microgravity condition. Further, ignition delay time is shorter in microgravity condition than in normal gravity. It is because no natural convection leads to make heat and vapor of insulation material stay around sample. If we have more microgravity condition, there is a possibility that the ignition limit will be extended toward low electric current condition.
