This guiding technical document specifies the general requirements for reliability verification testing of residual current operated circuit breakers (hereinafter referred to as residual current operated circuit breakers) for household and similar purposes, including reliability indicators, reliability levels, reliability test conditions, reliability test plans, reliability test procedures, etc. This guiding technical document is applicable to products that comply with the provisions of GB 16916.1-2014 or GB 16917.1-2014 standards. It is applicable to residual current operated circuit breakers with or without overcurrent protection for household and similar purposes, with AC 50 Hz, 60 Hz, or 50 Hz/60 Hz, rated voltage not exceeding 440 V, rated current not exceeding 125A, rated short-circuit capacity not exceeding 25000 A, and operating functions unrelated to or related to power supply voltage. This guiding technical document can serve as a guiding document for manufacturers to develop reliability indicators and test methods for residual current operated circuit breakers. The reliability level and test methods of residual current circuit breakers that comply with GB 14048,2 and other standards can also refer to the relevant content of this guiding technical document. The following normative references are essential for the application of this document. For dated references, only the dated version applies to this document. For undated references, the latest version (including all modification orders) applies to this document.
