[QUOTE="Doc Hudson, post: 477583, member: 1607"] So if you only have a continuity tester, and you have just come out of your time, you will fully understand the concepts of dead-testing, R1+R2 and polarity tests. AS such you should have more than enough knowledge and skill to fully test every aspect of continuity around the whole circuit thus identifying any breaks at any point in the circuit. You will of course also know that you need to test the Insulation Resistance of the circuit to ensure no cable damage. If there is a dead short anywhere, (that your testing should have identified), this could quite easily damage the internal working of the MCB. But you can of course verify continuity through the MCB with the power off. I am assuming you are also aware that a faulty circuit could appear to work fine for weeks or months before a damaged or faulty connection finaly fails. So without the full testing prescribed by BS7671 you cannot actually say something is fine just because there appears to be power there working for a few days. Doc H. [/QUOTE]
