IEC 61439-2 covers aspects such as:

IEC 61439 completely eliminated the TTA and PTTA terminology. Instead, it introduced a unified, precise engineering approach based on and Routine Verification . The Structure of the Series

Design Verification (the most critical part, replacing "Type Testing").

Power switchgear and controlgear assemblies (PSC-assemblies). iec 614391 and 2 pdf

Can be verified via calculation with strict derating factors or physical testing.

: Checking wire routing, terminal tightness, labelling, and compliance with the approved drawings.

One of the most significant shifts introduced by the IEC 61439 series is the clear distinction between the roles of the two types of manufacturers involved in creating an electrical panel: The Original Manufacturer IEC 61439-2 covers aspects such as: IEC 61439

Integrity of protective circuits and grounding.

: Establishes strict guidelines for mechanical strength, IP (Ingress Protection) ratings, electrical clearances, creepage distances, and protection against electric shock.

Critically, . It is a pure "general rules" document that must be read in conjunction with a specific product part (such as Part 2). Part 1 provides the common rules; the other parts apply the specific requirements for particular assembly types. Power switchgear and controlgear assemblies (PSC-assemblies)

Note: If you were referring to a different or non-existent standard ("iec 614391"), no such document exists. The correct references are IEC 61439-1 and IEC 61439-2.

It applies to assemblies intended for distribution of electrical energy in systems (up to 1,000 V AC or 1,500 V DC). This includes:
