Residual current fault codes
18 codes across 12 brands whose manufacturer wording names residual, leakage or ground-fault current.
A family groups codes by the manufacturer's wording. It does not mean the codes share a cause, a trip setting or a fix: the same words can describe different measurements on different hardware, so work each code from its own entry and its manufacturer's document.

Symptom-led sequences and checks that record the evidence for this kind of alarm. Follow the code's own entry for its documented step.
Guided decision trees
Members with a reviewed, step-by-step walk of the manufacturer's own procedure. Each opens on the code's entry.
Standards scope
Scope pages: what each standard covers and where it sits against the others. They do not reproduce the standard, and nothing on this page states what it requires. Work from the current published edition.
How codes are placed here
A code joins only when the manufacturer's own title or description contains one of these terms as whole words. The title decides first; Wattbench's fixes and search keywords are never read. A code that matches no family, or more than one, stays unclassified.
