IEC60364443

IEC 60364-4-43 is a standard within the IEC 60364 family, which governs electrical installations of buildings. The 60364-4-43 part focuses on protection against electric shock through the use of protective measures and the requirements for selecting and erecting those measures in electrical installations.

The scope of IEC 60364-4-43 covers how designers and installers determine appropriate protective strategies in different installation contexts, considering factors such as the type of premises, accessibility of circuits, wiring methods, and the potential fault conditions that could occur. It provides criteria to ensure that protective measures are suitable for the specific environment and electrical system being installed.

As part of the broader 60364 framework, IEC 60364-4-43 interacts with other sections that define fundamental requirements and complementary protection schemes. It supports safety objectives by outlining planning, documentation, verification, and ongoing testing of protective measures, and it commonly informs national standards and building codes through international practice.

The standard is maintained by the International Electrotechnical Commission and is adopted internationally, though national and regional bodies may publish jurisdiction-specific versions or adaptations. Like other IEC 60364 components, the content of IEC 60364-4-43 is periodically reviewed and revised to reflect advances in technology, safety practice, and regulatory needs.
