The standard is divided into several key tables and clauses, which are often referenced by page number in unofficial or scanned PDF copies. The most recent editions (e.g., Edition 7.0, 2009 – still the current major version as of this writing) include: : The primary standard is 230/400 V
Instead, usually refers to:
IEC 60038 applies to AC transmission, distribution, and utilization systems (50/60 Hz) above 100 V, DC and AC traction systems, and various low-voltage equipment. Key classifications include: iTeh Standards Low Voltage (100–1000 V AC): Focuses on harmonizing systems toward the 230/400 V standard The most recent editions (e
