Solution for two small busbar segments

A double-busbar switchgear uses two main busbars running in parallel. Each circuit can connect to either bus, allowing power to switch between them without cutting off supply. This setup offers higher reliability and flexibility. For such complex buses, busbar protection must be able to protect each bus segment individually, and dynamically keep track of the circuits. d busbar designs. This process, called “jointing,” may be needed to create a longer busbar from shorter, more manageable pieces; or to create a T-shaped tap-off connection from the main busbar. Complete solutions for AC or DC applications. ) can be manufactured into the conductors. An alternative ground plane may be added as support for the bus bar assembly and to provide a platform for mounting hardware.
