GB/T 10233-2016Basic testing method for low-voltage switchgear and controlgear assemblies (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard instead of GB/T 10233-2005 "low-voltage switchgear and electrical control equipment basic test method", and GB/T 10233-2005, the main technical changes are as follows.

--- the contents of the test of the empty shell of the complete set of equipment;

- Added the measurement of the electrical clearance and creepage distances in Appendix A, removing the contents of the original appendices A, B, C and D.

1 Scope

This standard specifies the basic requirements of low-voltage switchgear and electronic control equipment (hereinafter referred to as complete sets of equipment) type test and factory test method.

This standard applies to the test items specified in GB 7251.1-2013 and GB/T 3797.
