BR-UL-WCS Wiring Compartment Securement Tester
Perform standards: UL 1703-2012, IEC 61730-1:2004
Field wiring compartments with covers
Modules designed for the application of a permanently attached wiring system by an installer in the field shall be provided with an enclosed wiring compartment, which provides protection of the conductors and connections from environmental stress, protection from accessibility to live uninsulated parts and strain relief for the attached wiring system.
Wiring Compartment Securement Test
The tensile force required to separate a wiring compartment or box from a module shall not be less than 155.7N or 4 times the wiring compartment or box weight, whichever is greater, when tested as specified in following. For a test in which the superstrate or substrate fails prior to the adhesive, the force required to cause the superstrate or substrate to fail shall be used to determine compliance, and shall not be less than the specified minimum separation force.
Seven assemblies consisting of a wiring compartment or box secured to a module with adhesive as intended are to be tested. One assembly is to be tested in the as-received condition, three after being conditioned in accordance with temperature cycling test, section 35, and three after conditioning in accordance with humidity test, section 36.
The force is to be applied to each assembly so as to separate the wiring compartment or box from the module. The force is to be applied until the wiring compartment or box and the module separates; or the superstrate or substrate fails.
