Busbar trunking temperature rise and short-circuit withstand are known and inde pendent of the installation. Coordination of the Schneider Electric system results in complete control of the electrical network.
“Installation standards IEC 60 364 chapter 5.523.6 stipulate that above 4 parallel cables, it is preferable to use busbar trunking. Paralleling many cables leads to uneven distribution of currents and the risk of abnormal temperature rise. The busbar trunking and plug-in units are designed to guarantee the safety of personnel and equipment :
# Fully silver-plated cooper contact solution.
# bolted connections with tightening torque guaranteed by torque nuts.
# foolproof system to avoid the risk of assembly errors
