Afternoon guys.. In the picture of my Robin RCD tester you can see various operational procedures to test. Basically is it really necessary to flip through the 180 deg and keep switching this and switching that? - Can I not just use the x1 @30mA? - reason for asking is that soon I will be doing tests on my new system, and want to check everything is within limits before the Electrical Inspection chap checks my work. Thanks guys..
I always have checked 0 & 180 JP, only that way can you get a true reading. You always enter on the form the highest reading that you get on the 1x & 5x test & without doing both tests you can't really be sure you are doing that. Most testers nowadays do these tests automatically without flicking the switch
Thanks very much Wally. So on the 1 x I take the readings on 0 and 180 and use the highest figure, and then ditto on the 5 x - at least I now know because I was doing the tests and it really hacked me off keep going back to the DB and re-setting the RCD - but with my tester I must do this and accept that now. I could never warrant buying a Fluke etc which auto does the tests as it would only gather dust tbqh. . I've done a cursory test and the RCD is tripping at 21 milliseconds but that's all on a temp hookup. Once I get my RCBO populated DB in then I can do the tests proper on all RCBO's. Thanks once again Wally.
Stupid question - but do you check the trip times on every socket with ref to RCD? Also ELI - do you check every socket outlet/lamp holder etc on the circuit/s or just take it from the furthest one? Also polarity tests on ES lampholders - all Lives on mine are on the centre which I have verified - is this enough? My tests will be as follows : - ELI on all circuits Polarity check on ES lampholders End to end continuity on Ring Final Continuity on lighting circuits Continuity on other circuits IR at DB position - tails joined and to earth RCBO trip times Anymore to add guys? Thanks Also when testing ELI on lighting circuits from say the furthest ceiling rose - do I have to use all the leads on my SL16 test lead - ie one croc to earth, one croc to Live and one croc to Neutral? Thanks guys
You should test rcd tripping times at the output terminals of the rcd itself with all the breakers switched off JP, then no need to keep traipsing back to the board!
Hope you are going to do them in the correct order JP, not the order you have listed. Kind regards BS
