GB/T 37751.1-2019 is the English-translated version of 家用和类似用途的剩余电流动作断路器 第1部分：剩余电流电器标准的独立模块和单元模块概述.

GB/T 37751.1-2019 is the Chinese standard "Residual current operated circuit-breakers for household and similar use -- Part 1: Outline of blocks and modules for residual current devices standard".

Its scope clause reads: This series covers the public standards available for use in combination with the Residual Current Appliance (RCD) standard or drafting RCD standards.

This part of GB/T 37751 applies to RCD standards drafted by means of independent modules and unit modules.

This section defines methods and procedures for drafting standards based on new approaches (hereafter referred to as independent modules and unit modules), with the aim of coordinating Family standards to avoid errors, inconsistencies, or differences in family standards.

The same family criteria considered in this section include without overcurrent protection. Residual current operated circuit breaker (RCCB), residual current operated circuit breaker (RCBO) with overcurrent protection and residual current operated protective device General safety requirements for (RCD) (ie GB/T 16916.1, GB/T 16917.1 and GB/T 6829).

This approach defines a way to optimize the drafting of standards, with the aim of maintaining a common or similar structure, using common terms whenever possible.

Avoid inconsistencies and do only one editorial work, thus speeding up the drafting of standards and ensuring that the opinions in one standard are also Considered in the same family standard.

The principles of the stand-alone module and the unit module approach are. --- Determine the parts of the standard that need to be unified (or have limited differences) and the parts that should be kept different in the standard; --- Establish a technical committee database for the shared part; --- Identify the parts that need to be published as an independent standard; --- Use the technical committee database to draft product standards; --- Track the common parts of the product standard when revisions are needed in the future.

This section also lists the stand-alone modules and unit modules for drafting RCD product standards. Its clauses include terms and definitions.
