How guides are prepared

Sources first

I start with primary sources where they are available: public authorities, standards bodies, network operators, manufacturers and official technical documentation. Secondary sources can help identify a question but do not replace the source that establishes a rule.

Country scope

Every guide is written for its stated market. Similar voltage, language or equipment does not make a rule transferable. International material is identified as such and never presented as a substitute for local requirements.

Field observations

Photos, tool use and installation observations come from my own work when stated. They show a real situation, not a universal instruction. Work on live circuits, damaged conductors, heat, smoke or water near electricity requires a qualified local electrician.

Updates, corrections and commercial transparency

To report an error, send me the URL of the guide, the exact passage concerned and, if available, an open primary source that establishes the correct fact. You do not need to share personal details about an installation.

After verification, I correct the guide, update its verification date and record on the guide any correction that changes a material conclusion. Product loans, gifts and sponsored relationships are disclosed in the relevant article.
