In this one then….. Consumer unit RCD test, with a bit of comedy and fun chucked in for a good measure. Crow bars usually aren’t needed, but there’s one in this vid! :D

So, what happens in an RCD test?

Firstly we look at the RCD type and its trip rating.

It is a standard-domestic one, tripping at 30mA.

RCD tetsing is a =LIVE TEST= so be advised!

The tester used in this video has to be set up according to the RCD type. The tester can carry out the following types:

Standard AC, Time-delayed AC, Standard DC, Time-delayed DC.

It can test up to the following trip ratings:

10mA, 30mA, 100mA. (500mA not available on auto-test)

Setting the tester to ‘Standard AC’ and current of ’30mA’, the tester is then put into ‘automatic’ mode whereby it carries out a sequence of tests automatically without having to return to the tester, select the next test, going to the RCD, resetting it, back-and-forth for each test.

In auto mode, the tester is started, then you just wait at the RCD for when it trips. In auto mode, a good RCD should trip four times.

The tester will actually perform SIX auto-tests, as follows:

(1) Half-rating (15mA in this case) at zero degrees in the sinewave.
(2) Half-rating (15mA again) at 180 degrees in the sinewave.
(3) Full-rating (30mA in this case) at zero degrees in the sinewave.
(4) Full-rating (30mA again) at 180 degrees in the sinewave.
(5) 5x rating (150mA in this case) at zero degrees in the sinewave.
(6) 5x rating (150mA again) at 180 degrees in the sinewave.

-end of test with a RCL shown on the display (recall test results)

For a good RCD, there should be no trip on tests 1 & 2, but should trip on tests 3,4,5 and 6, and within specified times, as this isn’t just about whether it trips or not, but whether it trips within an allowed time.

Yes, a RCD may trip on a test, but it may still fail if it takes too long to operate.

Testing time-delayed RCDs is another story, and time-delayed RCDs are not used in domestic situations.

The consumer unit tested in this video is just a ‘loose’ one I have sitting around, and may feature in other future videos.

Thanks for watching, peoples.
