IEC 60364-5-52:2009/COR1:2011

IEC 60364-5-52:2009/COR1:2011 is a corrigendum linked to the Low-voltage electrical installations series, addressing the Part 5-52 guidance on selection and erection of electrical equipment for wiring systems. As a supporting document to IEC 60364-5-52:2009, it is relevant when teams need to verify the current technical wording before using the base document in design, installation, or compliance workflows. For engineering review, procurement checks, and documented evaluation, the reference helps maintain technical alignment and reduce interpretation errors in wiring system decisions.

Purpose of IEC 60364-5-52:2009/COR1:2011

The purpose of IEC 60364-5-52:2009/COR1:2011 is to correct or clarify the parent document where needed, supporting more accurate application of the rules for wiring systems in low-voltage electrical installations. In practice, a corrigendum like this is used as a technical reference during design validation, specification review, and conformity assessment. It helps organisations work from the corrected text of the parent publication when assessing electrical equipment selection, erection practices, and installation documentation.

Compliance applications of IEC 60364-5-52:2009/COR1:2011

IEC 60364-5-52:2009/COR1:2011 is commonly used alongside the parent standard in regulatory preparation, technical assessment, and quality workflows for low-voltage installation projects. It may support engineering documentation for wiring system selection, installation planning, and verification activities where accuracy of the referenced text matters. Compliance teams, consultants, and installers can use it to confirm that project specifications, test records, and procurement documents reflect the corrected requirements associated with IEC 60364-5-52:2009.

Benefits of IEC 60364-5-52:2009/COR1:2011

Using IEC 60364-5-52:2009/COR1:2011 improves technical consistency by ensuring the parent document is applied with its official correction in place. That can support safety-focused installation decisions, reduce interpretation risk, and strengthen engineering validation across design and commissioning stages. It is also useful for procurement and conformity assessment preparation, where precise standards references help avoid documentation gaps. For organisations managing compliance workflows, the corrigendum supports more reliable review of wiring system requirements and related technical document control.
