The developed in-flex system completed the wiring work with the plug-in connection. To maintain electrical and mechanical stability, and an insulation between the conductors was strengthened by forming a partition. Moreover, the error according to a bad connection was prevented by separating the inlet from the outlet of the electric trace and thus the quick construction become possible. The metal reinforcing material was added outside the upper case and lower case. The fire-resistance efficiency was maximized in order to minimize a damage by the fire. As to the developed system, we found that it takes shorter time to complete installation than the rigid steel conduit wiring work, and that about 25 % of construction cost was saved because the labor costs decrease due to the shorter construction period of time.
