<p><P>PROBLEM TO BE SOLVED: To enable the optimum wraparound of inlet port wiring reaching a through hole by eliminating inconvenience that the inlet port wiring is protruded to the side of a branching box, and by selecting the position of the through hole that the inlet port wiring penetrates according to the status of a site, in a low-pressure branching device that branches a lead-in wire from a trunk line of a low-pressure in-ground wiring cable. <P>SOLUTION: The low-pressure branching device comprises a steel pipe 10 erected on the ground, and the branching box 3 fixed to the upper end of the steel pipe 10. The steel pipe 10 is installed on the center line between the right and left of the bottom 11a of the branching box 3, and a plurality of knockout parts 15 that forms the through hole 16 are formed on the bottom 11a of the branching box 3 around the circumference of an installation region of the steel pipe 10 with the region as a center. The inlet port wiring 4, 5 are made possible to penetrate the through hole 16 formed by eliminating the arbitrary knockout parts 15, and the lead-in wire 2 led in the steel pipe 10 is connected to the inlet prot wiring 4, 5 directly or via the fuses 6, 7 in the branching box. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
