Appendix 5. Inspection procedure RCD performance in the electrical circuit of the building
To test the performance of RCD in the electrical circuit of the building is necessary to use a special device - ASTRO * TEST.
This device allows you to determine the presence of the electrical circuit protective conductor PE and reliability of its connection to the earth.
The device ASTRO * TEST simulates flow limited in time (up to 200ms) leakage current set value equal to the rated residual operating current of the RCD.
The device allows ASTRO * TEST to verify complex electrical safety measures - serviceability of protective conductor PE, the right choice of settings RCD, RCD selectivity of action with a multi-stage protection system, the reliability of the terminal connections, etc. in electrical systems.
The device ASTRO * TEST due to a time limit (up to 200 ms) test current flow ensures complete electrical safety of the personnel performing the tests (Fig. Section 5.1).
Figure clause 5.1. An example of connecting the device ASTRO * TEST
