If it is a power distribution cabinet applying for certification in accordance with the GB 7251.1-2005 standard, at least the following detection and testing equipment is required:
1. Withstand voltage tester, AC 5000V voltage, leakage current 100mA is recommended, type 2672 is recommended
2. Ground resistance tester, the adjustable current should not be less than 10A, the range is 0-100mΩ, type 2520 is recommended
3. Insulation resistance meter, 1000V
4. Vernier caliper,
5. Power-on test bench (debugging bench), which has the function of current and voltage debugging.
Of course there should be a certificate of passing the test.
