Home / Wiring Standards for Low-Voltage Switchgear
IEC 60439, the standard for low-voltage switchgear and controlgear assemblies, was under restructuring from the last decade. Regarding product liability for example, injured parties will only have to demonstrate that their le-gal rights have been violated and that this violation led to a loss and that the manufacturer has intro-duced a defective product to the market and that. When it comes to designing safe, efficient, and reliable low voltage electrical panels, one standard stands above the rest: IEC 61439-1.
