Inspection and Licensing Service for Low Voltage Switchgear Systems

What Is Inspection and Licensing Service?

EAE Electrotechnics' inspection and licensing services are carried out by our supervisors to ensure that the PanelMaster switchgear, which are assembled by our PanelMaster partners, are in compliance with PanelMaster design and application rules.
The purpose of this process is to ensure that customers purchase a truly type-tested panel system. This is accomplished through inspections to confirm that PanelMaster low voltage panel systems, manufactured by EAE Electrotechnics with type tests performed by internationally accredited DEKRA laboratories in compliance with IEC 61439-1/2, are assembled in accordance with the design and application rules.
The inspection and licensing process for low voltage type tested systems is exclusive to PanelMaster. Authorized PanelMaster partners are the sole providers of PanelMaster type-tested switchgear installation and sales.
EAE Electrotechnics has an inspection services unit within the company to control switchgear specifically that is installed by the partners. Our supervisor visits the partner's workshop for inspection to verify that installed switchgear meets PanelMaster's design and application rules. Upon successful inspection, a detailed inspection and licensing report is prepared and shared with both the client and the authorized partner. If a situation contrary to the design and application rules is detected in the switchgears, the supervisors team does not approve them, and the necessary corrections are reported instantly to the panel builder. 

Some Key Control Points in Inspection and Licensing

Protection Against Short-Circuit

Distance measurement between phases
Distance measurement between insulators and compatibility for short-circuit current 
Use of original insulators 
Compliance of switchgear materials with the project

Protection Against Overheating and Fire
Control of copper conductor cross-sections
Measurement of the intrinsic conductivity (purity) value of copper busbars
Torque control of connection bolts
Mechanical and Electrical Checks
Verification of mechanical operation
IP (ingress protection) level check
Control and command circuit check
Labeling and documentation check
Protection Against Electric Shock
Earthing conductor cross-section check
Earthing continuity measurement
Insulation (dielectric) tests
Distance measurement between connection terminals and bolts

Is An Inspection and Licensing System Mandatory According To The IEC Standard?

Inspection and Licensing is not a mandatory requirement in the IEC 61439-1/2 standard. Inspection and Licensing is a special practice implemented by EAE Electrotechnics to eliminate the dissatisfaction of customers and employers since many original manufacturers and assmebly manufacturers (panel builders) operating in the low voltage enclosure market do not fulfill their responsibilities assigned to them in the standard.

Who Are The Manufacturers In LV Switchgear Systems And What Are Their Responsibilities?

In the IEC 61439-1/2 standard, two manufacturer definitions are made for low voltage switchgear systems:
Original Manufacturer: The organization that designs and verifies the switchgear in accordance with the 61439-1/2 standards.
Final Manufacturer (Panel Builder): The organization that performs the electrical installation of the designed and verified switchgear in strict adherence to the original manufacturer's design rules and takes responsibility for the manufactured switchgear.
Note: The Final Manufacturer can be a different organization from the Original Manufacturer.
For the type test conditions to be fully met, it is mandatory for the Assembly Manufacturer (panel builder), who makes the electrical installation, to fulfill its responsibilities specified in the standard, as well as the responsibilities of the original manufacturer who produces the panel, performs the type tests and documents them. The original manufacturer must provide the assembly manufacturer with documentation detailing the design and assembly rules, type tests and certifications for the panels it produces.
Based on the definitions provided, both the original and assembly manufacturers have distinct responsibilities to fulfill.

61439-1/2 Responsibilities of Original Manufacturer and Final Manufacturer

Original
 Manufacturer
Final Manufacturer
Manufacturing Low Voltage Enclosures
Design Verification Through Experimentation, Calculation, and Comparison for Certification
Providing General Assembly Instructions to Manufacturers
Electromechanical Installation acc. to General Rules by Original Manufacturer
Verification of Routine Test
Complete Panel Assembly and Preparation for Shipment
This unique inspection and licensing system implemented by EAE facilitates a deeper understanding of type test standards among panel builders, ensures compliance with project specifications, and enables contracting and investing companies to procure fully type tested switchgears. In this way, it is guaranteed that our customers receive a type tested switchgear with design verification and control, rather than a switchgear that merely appears to be type tested solution.
