If these relationships are not achieved then downlaod the conductors are incorrectly identified or there is a loose connection at one of the accessories!
However, in most circumstances this will not be practicable and the following test method for checking ring circuit continuity is recommended. If the protective conductor has a reduced csa, the resistance of the protective loop will be proportionally higher than that of the line or neutral loop.

In-service safety inspection and testing ekectrical electrical equipment. A finite reading confirms that there is no open circuit on the ring conductors under test. The line, neutral and protective conductors are identified and their resistances are measured separately see Figure 2.
In-service safety inspection and testing of electrical equipment: The test will also establish that electrkcal ring electrical testing and commissioning books pdf download not broken. It may be possible, as an alternative and in order to establish that no interconnected multiple loops have been made in the ring circuit, for the inspector to check visually each conductor throughout its entire length.

The end-to-end resistance of the protective conductor is divided by four to give R2 and is recorded on the installation schedule form. Functional testing of control systems. Commissioning the static equipment: Electrical switchboard Practice s for Construction Work: Practice s for Construction Work: Validation of proper and thorough installation of BA S and equipment. The test results should establish that the ring is complete and has no interconnections.
