IEC 61439 is a standard developed by the International Electrotechnical Commission (IEC) that covers design verification for low-voltage electrical products and assemblies. Busbar design within Medium Voltage (MV) switchgear is a critical aspect, fundamentally ensuring the safe, reliable, and efficient operation of power systems. The IEC 61439. Annex D was introduced in the april 2020 version of UL 508A. It clarifies what was previously common but not formally correct practice. A manufacturer of electrical automation panels is not required to use a certified busbar system or to subject it to short-circuit tests, provided that it complies. 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. The adoption of busbar power distribution systems on a global scale has accelerated in the. Double spacer for easy leveling and connecting on both sides (snubber. ). From time to time we are asked what bus spacings are required by ANSI standards for switchgear. Those who ask are frequently surprised by the answer: None. ANSI switchgear standards are generally performance standards. Dielectric tests, power frequency withstand for all voltages and impulse.
