The distance between vertical supports is permitted to be up to 6m according to electrical equipment regulations in Japan (check and conform with the regulations in your country), but we recommend providing floor support on each floor. In cases where floor height is 4m or higher, we recommend installing intermediary sway-bracing systems.
※Number of support bolts will vary depending on the capacity of the bus duct.
The distance between horizontal supports must be no less than 2m.
Additionally, be sure to install earthquake-proofing supports at appropriate intervals according to your construction guidelines and planning for facility earthquake proofing.
※For dimensions W and H, refer to chart on page 6 "Bus Duct Dimensions" in catalogue.
