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 Part of 2,116,916.

This section identical with IEC 61008-2-1:1990 "Household and similar uses overcurrent protection for residual current operated circuit breaker (RCCB) - Part 2.1. General rules for the operation of the functions independent of 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 16916.21-1997, the main difference between this part and GB 16916.21-1997 follows.

--- The whole standard "line voltage" to "supply voltage";

--- Chapter 6 "n) item" to "m) item";

--- The "9.11.2.1a) the last two" to "9.11.2.1a) last paragraph." 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.
