Shenzhen ZhongNuo Testing Technology Co., Ltd. offers consultation services for the application of explosion-proof electrical installation, maintenance, and maintenance qualification certificates.
The Explosion-proof Electrical Equipment Installation, Inspection, and Maintenance Manual requires a company and at least 3 certified employees to perform the work together. An additional fee applies for each extra employee.
If an employee leaves, they cannot take the certificate with them.
It is generally recommended that employees with long-term stability attend the ZN testing.

Many construction firms, particularly when undertaking projects involving installations in explosive areas, receive the projects.
Property owners will require them to provide relevant certificates for explosion-proof electrical installation and construction.
That's what we refer to as the "Qualification Certificate for Installation, Maintenance, and Repair of Explosion-Proof Electrical Equipment."

Installation, maintenance, and inspection documents for explosion-proof electrical equipment are mainly handled by institutions such as Shenchuan, Jiamusi, and Nanyang Explosion-Proof.
