When type testing, the electrical distribution panel is subjected to a series of standard tests that simulate different operating conditions and fault conditions. Independent testing laboratories and certifying organizations often perform these tests.
A type-tested electrical panel is a type of electrical panel that has been extensively tested and certified in accordance with internationally accepted standards. These tests are performed to ensure the panel's performance, safety and compliance with certain design criteria and operating conditions. The main purpose of panel type testing is to ensure that the panel meets or exceeds performance and safety specifications.
The main type tests performed on an electrical panel include:
Once a panel has successfully passed these tests and meets the relevant standards (e.g. “IEC 61439-2 Low voltage switchgear and control assemblies - Part 1: General rules” and “IEC 61439-2 Low voltage switchgear and control equipment assemblies - Part 2) developed by the International Electrotechnical Commission 891: After meeting the “Power switchgear and control equipment assemblies” standards or the “UL XNUMX Switchboards” standard developed by Underwriters Laboratories, a type test certificate or label is issued confirming its conformity, indicating that the panel has been independently verified and meets the required performance and safety standards. provides assurance.
Panel type tested electrical panels are routinely used in industrial facilities, critical infrastructures, hospitals, data centers and a variety of other facilities where reliability, security and compliance with standards are important. These panels provide a high level of assurance and are recommended for applications involving stringent regulatory requirements or project specifications.
Once the wiring has been verified in a facility, it is necessary to test the panel or breaker for functionality and safety. A circuit tester or voltage tester is used to check the voltage and current of each circuit. A clamp meter is also used to measure the current draw of each load. The readings are compared to the characteristics and ratings of the panel or breaker. If there are any discrepancies, it may be necessary to change settings, replace components, or add protective devices.
In short, panel type tests are tests that ensure reliability and safety. These tests are carried out by advanced laboratories with factory-made connections and prototypes with distribution and connection systems applied. However, although the rules in the IEC 61439-1 and IEC 61439-2 standards, which examine low voltage panels more comprehensively and stipulate design verification rules, are very clear in practice, there are major deficiencies in practice.
