TC4 Switchgear, control gear and associated equipment

Scope/Introduction: || back to top

ETCI TC 4 is actively involved in the work of IEC TCs 17 and 23 and CENELEC TCs 17B, 17D and 23E, except RCDs. The matter of Residual Current Devices (RCDs) was delegated to a Task Force on which some members of TC4 also serve.

The current work of the committee is to maintain the two published Codes of Practice:

  • Code of Practice for the Design, Selection and Erection of Low Voltage Switchboards for Industrial and Commericial Applications.
  • Code of Practice for the Design, Selection and Erection of LV Switchboards for Residential Applications.
