Set the function switch to X1 for the

“

trip

”

test, which measures the time

taken for the RCD to trip with the set residual current.

．

Set the "LOOP/RCD" switch to 0

．

Make sure that the P-E and P-N wiring check lamps are lit. If they are not,

disconnect the tester and check the wiring for a possible fault.

．

If the lamps are lit, press the test button to apply full rated tripping current

and the RCD should trip, the tripping time being shown on the display. If

the RCD has tripped the PN and PE LEDs should be off. Check this is so.

．

Repeat the test with the "LOOP/RCD" switch at 180

．

MAKE SURE TO KEEP CLEAR OF EARTHED METAL DURING THE

OPERATION OF THESE TESTS.

7.4

Testing RCDs used to provide supplementary protection. (FAST TRIP

TEST)

RCDs rated at 30 mA or less are sometimes used to provide extra protection

against electric shock. Such RCDs require a special test procedure as follows:-

．

Set the "RCD"switch to "150 FAST".

．

Set the "LOOP/RCD" switch to 0

．

Connect the test instrument to the RCD to be tested.

．

Make sure that the P-E and P-N wiring check lamps are lit. If they are not,

disconnect the tester and check the wiring for a possible fault.

．

If the lamps are lit, press the test button to apply a test current of 150mA

where the RCD should trip within 40ms, the tripping time being shown on

the display.

．

Repeat the test with the "LOOP/RCD" switch at 180

．

MAKE SURE TO KEEP CLEAR OF EARTHED METAL DURING THE

OPERATION OF THIS TEST.

7.5

Testing time delayed RCDs

RCDs with a built-in time delay are used to ensure discrimination, that is, that

the correct RCD operates first. Testing is carried out in accordance with item

7.3 above, except that the displayed tripping times are likely to be longer than

those for a normal RCD. Since the maximum test time is longer, there may be

danger if earthed metal is touched during the test.

MAKE SURE TO KEEP CLEAR OF EARTHED METAL DURING THE

OPERATION OF THIS TEST.

Note

：

If the RCD does not trip the tester will supply the test current for a
