IEC 61936-1: Designing Safe Power Installations Exceeding 1 kV A.C.
If you are an equipment manufacturer, a failure to comply means no CE marking. If you are a plant operator, non-compliance is an indefensible liability in the event of an accident.

IEC 61936-1 is not just a dry technical document—it is a between the designer and the operator. It acknowledges that while HV systems are inherently dangerous, proper design based on clearances, earthing, and switching procedures makes them intrinsically safe to operate and maintain.
When you step beyond the low voltage threshold of 1,000 volts AC, the rules of the game change dramatically. Arc flash risks increase, clearance distances grow, and the consequences of a single design flaw can be catastrophic.
