Can the circuits and wires removed from the hotel be used? Is it safe?

The removed circuit wires cannot be used again.

Don't use the circuit wires removed from the hotel, because the removed wires may have been damaged or aged, which may pose a safety hazard. In addition, the removed wires have not passed the qualified installation and acceptance, nor have they passed the professional maintenance and testing, so the quality and safety cannot be guaranteed. If these wires must be used, they need to be thoroughly inspected and tested to ensure that they meet safety standards.

In practical engineering, in order to ensure the safety and reliability of electrical equipment, qualified wires and electrical equipment should be used and installed and maintained in accordance with the requirements of the specification. If it is necessary to replace or remove the wires, it should be operated by professionals to ensure that other electrical equipment will not be affected during the operation, and to ensure that the removed wires are handled safely and reasonably.
