Requirements for Parallel Operation of 10kV Busbars
The current flowing from the cable sockets is supplied to the parallel busbars via the cir-cuit-breaker and via both disconnectors - in this case operated in parallel. IEC 61439 is a standard developed by the International Electrotechnical Commission (IEC) that covers design verification for low-voltage electrical products and assemblies.

A recent study found that there are roughly 30,000 arc flash incidents in the United States each year, many of which are powerful enough to cause significant injury to workers and costly damage to equipment2. These guidelines are established by international and national standards organizations, such as IEC and ANSI/IEEE, assuring the long-term performance of busbars and the overall reliability of switchgear. They represent indispensable principles that modern power system engineers must thoroughly.
