Low voltage (≤1 kV) is primarily covered by IEC 60364 (Low-voltage electrical installations).

The standard covers several critical technical areas for high-voltage design:

IEC standards must be read alongside local regulations (e.g., NFPA 70E in the US, BS 7671 in the UK). Local codes often impose stricter touch voltage limits or fire separation rules.
