Residual Current Operated Circuit-breakers Without Protection for Household and Similar Uses (RCCBs)

The Dominica Bureau of Standards (Bureau) was established under the Standards Act (#4) of 1999. The Standards Act gives the Bureau responsibility to facilitate the development and promotion of Standards and Codes of Practice for products and services. As a result, this provides protection of the health and safety of consumers and the environment as well as for industrial development in order to promote the enhancement of Dominica's economy.

The Bureau develops Standards through consultations with relevant interest groups. In accordance with the provisions of the Standards Act, public comment is invited on all draft Standards before they are declared as Dominica National Standards (DNS).

In light of this, the following Standards are being issued for Public Comments:

Comment form for this standard (DOCX, 191 KB)
IEC 61008-1:2010+A1:2012+A2:2013 applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating overcurrent protection (hereafter referred to as RCCBs), for rated voltages not exceeding 440 Va.c. with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A, intended principally for protection against shock hazard. This third edition cancels and replaces the second edition published in 1996, amendment 1 (2002) and amendment 2 (2006). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
  • complete revision of EMC sequences, including the new test T.2.6 already approved in IEC 61543;
  • clarification of RCDs current/time characteristics reported in Tables 1 and 2;
  • revision of test procedure for IΔn between 5 A and 200A;
  • testing procedure regarding the 6mA d.c. current superimposed to the fault current;
  • improvement highlighting RCDs with multiple sensitivity;
  • tests for the use of RCCBs in IT systems
This consolidated version consists of the third edition (2010), its amendment 1 (2012), its amendment 2 (2013) and the corrigendum of January 2014. Therefore, no need to order amendments in addition to this publication.
IEC 61008-1:2010+AMD1:2012+AMD2:2013

The period for Public Comments will run from 13 March to 12 May 2023.
