PROBLEM TO BE SOLVED: To provide a bus duct supporting system which minimizes a distance of bus ducts adjacent to each other and reduces space for arranging the bus ducts.SOLUTION: In a system to support the bus ducts of a plurality of systems juxtapositioned almost in a vertical direction of a structure, each bus duct is supported by a supporting portion fixedly installed on the structure, and a supporting portion to support one bus duct and a supporting portion to support another bus duct adjacent to the one bus duct are provided in a longitudinal direction of each bus duct with a distance therebetween. For example, with respect to the bus ducts juxtapositioned penetrating through a plurality of floors of the structure, at a first floor, one bus duct is supported by the supporting portion but another bus duct is not supported by the supporting portion, and at a second floor which is one floor higher than the first floor, the another bus duct is supported by the supporting portion but the one bus duct is not supported by the supporting portion. |
