These standards collectively form the regulatory framework for busbar design, ensuring that all design and testing processes are comparable
Exclude phase-to-phase short circuits. In worst case only phase-to-earth short circuits could happen. Minimizing of fault risks. No disconnecting of the busbar while outgoing feeder will be repaired or
A typical example would be when the busbar must lie close to the top of the switchboard, when avoiding other services or when there is reduced head height above the switchgear.
If this program recommends sizes that do not fit into the ranges below, change either the number of conductors or the section thickness of the busbar and recalculate the minimum cost solution
