GB 16916.22-2008Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCB) -- Part 2.2: Applicability of the general rules to RCCB functionally dependent on line voltage (English PDF)

Foreword

All technical content in this section is mandatory.

GB 16916 "Household and similar uses overcurrent protection for residual current operated circuit breaker (RCCB)" divided into the following section.

--- Part 1. General rules;

--- Part 21. General rules for the operation of the functions independent of line voltage RCCB applicability;

--- Part 22. General rules for the operation of the function and line voltage RCCB applicability.

This section GB 16916 of Part 22.

This section identical with IEC 61008-2-2:1990 "Household and similar uses overcurrent protection for residual current operated circuit breaker (RCCB) - Part 2.2. General rules for the operation of the function and line voltage RCCB applicability. " this section should be used and GB 16916.1-2003 "household and similar purposes without overcurrent protection RCBO (RCCB) - Part 1. General rules "together.

This Part replaces GB 16916.22-1997, the main difference between this part and GB 16916.22-1997 follows.

--- The entire text of the "line voltage" to "supply voltage";

--- Chapter 1, a paragraph, will further clarify the scope of IEC implied.

This part is proposed by the China Electrical Equipment Industrial Association.

The low-voltage electrical part by the National Standardization Technical Committee (SAC/TC189) centralized.
