Before Installing An Automatic Voltage Regulator, The Power Must Be Completely Disconnected And The Circuit Tested.

The voltage testing process should include verifying the mains power supply lines and the wires used for the 10kva stabilizer single phase input one by one. If the voltage tester shows a voltage reading, work must not continue; the power circuit must be disconnected again, and the measurement repeated to confirm no power before proceeding with subsequent wiring operations.

A qualified electrician should be present on-site to oversee this step. The verification process must cover the status of the neutral, live, and ground wires, ensuring that the voltage reading at each cable port is zero. This check is not a formality but part of complying with electrical engineering specifications, used to assess the electrical environment before connecting to 15 kva automatic voltage stabilizer, thereby ensuring that the initial installation conditions meet the operational requirements.

Only after completing the power-off and voltage testing can the 15 kva stabilizer single phase input/output terminals be connected and secured according to the design wiring diagram.
