<p>PROBLEM TO BE SOLVED: To easily branch and draw out an electric wire or cable from a common cable duct. SOLUTION: This branching method includes forming two circular holes, whose positions are shifted from each other with a hole saw in numeral 8-shaped hole 2 at the outer casing of a common cable duct, inserting a packing 3 having the numeral 8-shaped tubular leg part 5 from above the hole 2, and mounting a branch connector 6 which has a tilted draw-out part 8. An electrical wire or cable can be drawn out through the hollow drawing-out part 8 from the inside of the duct.</p> |
