I. Introduction

After the completion and acceptance of a newly built laboratory, or upon request from the laboratory, the Laboratory Services Department will arrange professional personnel to assist the laboratory in conducting comprehensive testing of the indoor electrical system before its official commissioning, ensuring electrical safety.

II. Operation and Maintenance Introduction

1. Distribution Box Circuit Testing: Includes circuit number, circuit breaker type/setting value, conductor type/section, insulation resistance (L-E/L-N/N-E), phase and polarity, grounding circuit impedance, voltage, current, etc.
2. Socket Circuit Testing: Includes socket circuit number, socket type, voltage value, neutral wire value, whether there is leakage, whether the wiring is incorrect, test results, etc.
3. Equipotential Grounding: Grounding resistance test, etc.
