Correct installation and coordination of internal electrical components.
Whether you are a panel builder aiming for IEC 61439 compliance, a consultant verifying a design, or a student entering the field, mastering these two documents is non-negotiable. Start with the official —and build safer electrical systems.
This is the "umbrella" standard. It contains all the general definitions, service conditions, construction requirements, performance characteristics, and verification methods that apply to any type of low-voltage assembly (up to 1,000 V AC or 1,500 V DC). iec 614391 and 2 pdf

Understanding IEC 61439-1 and 2: The Definitive Guide to Low-Voltage Switchgear Standards
The IEC 61439 series, published by the International Electrotechnical Commission, replaces the older IEC 60439 standard. It establishes the safety and performance requirements for low-voltage switchgear and controlgear assemblies (rated voltage not exceeding 1000 V AC or 1500 V DC).

But why are Parts 1 and 2 always grouped together? Simply put, you cannot fully understand or comply with Part 2 without Part 1. This article will dissect both standards, explain their symbiotic relationship, outline their technical requirements, and discuss the legal and practical realities of obtaining the official documents.
