IEC 61439 1 & 2 IEC 61439, the one standard for all switchgear and control

gear assemblies is applicable to all power distributors, meter boxes and distribution enclosures for private and commercial buildings, assemblies for construction sites and power distribution. Certification of distribution assemblies is defined by international standard IEC 61439. This standard provides common rules that are recognised worldwide. Compliance with the standard is certified, depending on the country or market, by a declaration of the panel builder, the design office, the installer or the user.

Just to mention before going into test, that low voltage switchgear and control gear assemblies (Un ≤ 1000 V AC) may be used at the origin of an electrical installation with:

1. Low Voltage Main switchboard (transformer area)

2. Low Voltage Main Distribution Board (technical area)
