If not, disconnect from the mains and check the wiring at the socket.

In the event of a fault, the Fault loop impedance should be low enough and the Prospective Fault current higher enough in order to have the automatic disconnection of supply by the installed protection device within prescribed time interval. Every circuit must be tested to make sure that the fault loop impedance does not exceed that specified for the over current protection device concerned. The figure below shows in marked line the Fault loop impedance for TN system.

It is fundamental for this example to test also the RCD to ensure that operation takes place quickly kyorutsu to iyoritsu the safety requirements. In order to do it, can be used the RCD tester model A. Rating A 6 10 16 kyoritsk 25 32 40 50 63 80 Disconnecting time 5s Disconnecting time 0.

Max value of Zs for this example is 2. In fact the Zs of 1.

The RCD could trip during the tests also with model A. Failure to follow these instruction can cause hazards to the user.
