Clause 2.3.3.4 Test for Operation of RCDs

When tested in accordance with Appendix D at intervals not exceeding those specified in Table 2, the maximum tripping time for RCDs shall not exceed the values shown in Table 1.

Notes:

1. The test for operating time using a.c. for Type A RCDs (a.c. and d.c. pulse sensitive) is acceptable as d.c. calibration is linked to a.c. calibration and verified by type test.

2. Portable RCDs which are permanently wired to terminals in equipment may be tested by push button only, observing the operating time, which should be without undue delay. In case of doubt, use an external timer circuit, capable of detecting the test current start and finish, to measure disconnect time of not more than 150mS for a 30mA unit and 40mS for a 10mA unit (the test button current is assumed to be 200% x rated residual current).

Test for Operating Time of RCDs (Residual Current Devices)

(Normative)

D1 General The operating time of RCDs shall be checked to Clause 2.3.3.4 with maximum values to Table 1.

D2 Instrumentation An RCD tester to apply rated tripping current ±5% and measure time ±2.5%.

D3 Test Conditions A current, equal to the rated tripping current, shall be suddenly applied between active and protective Earth and the operating time measured.

Notes:

1. Tests are applied by the instrument test button (suddenly applied). In case of doubt, the number of test operations, up to five, may be required.

2. Some RCDs may have a different result (approximately 10mS) depending on the point on wave of the test current. In case of doubt, operating time at both 00 and 1800 should be tested.

3. Load leakage and stored energy can affect the result and increase the meter trip time indication. In case of doubt all load on the circuit should be disconnected.

4. A 240V test meter, used on 230V may give a low test current and corresponding longer times. Ensure the correct rating and tolerance of the test instrument.

5. Tests on three-phase units are carried out on one phase only. In case of doubt, as the vector of the test current and the load leakage current are important, the load should be disconnected.

6. The test from Active to Earth involves the complete Earth fault loop and the resistance of the Earth wire, or current flowing in the Earth wire may affect results. In case of doubt, a bench test may be required.

Appendix D



7. Portable RCDs which are permanently wired to terminals in equipment may be tested by push button only, observing the operating time, which should be without undue delay. In case of doubt, use an external timer circuit capable of detecting the test current start and finish, to measure disconnect time of not more than 150mS for a 30mA unit and 40mS for a 10mA unit. (The test button current is assumed to be 200% x rated residual current).

The following tests are not required by this Standard:

(a) Calibration sensitivity at slowly rising current

(b) Non trip threshold (50% rated sensitivity)

(e) d.c. pulse tests for class A. The test for operating time using a.c. for type A RCDs (a.c. and d.c. pulse half wave sensitive) is acceptable as d.c. calibration is linked to a.c. calibration and verified by type test. The test for operating time, ensures that both type AC (sine wave a.c.) and type A have retained their type test calibration.



AS/NZS 3760:2003

Clause 2.3.2 Inspection

The following equipment checks shall be made by visual and physical inspection on all equipment:

• Checkforobviousdamageordefectsintheaccessories,connectors,plugs or extension outlet sockets.

Note:

(a) For low voltage portable equipment and cord extension sets fitted with AS/NZS 3112 type (flat pin) plugs and extension sockets, the use of clear backed or integrally moulded (non-rewireable) plugs, and cord extension sockets is recommended. Clear backed plugs and sockets facilitate the easy inspection of the effectiveness of the sheath grip.

(b) Check that flexible cords are effectively anchored to equipment, plugs and cord extension sockets.

Note:

• Thisinspection,includingflexingandstrainingatpointsofentryand clamping points, may be carried out in conjunction with the continuity test to Clause 2.3.3.1. This may detect broken strands or loose connections.

(c) Check for damage to flexible cords:

(i) The inner cores of flexible supply cords are not exposed or twisted.

(ii) The external sheaths are not cut, abraded, twisted, or damaged to such an extent that the insulation of the inner cores is visible.

(iii) Unprotected conductors or insulation tape are not in evidence.



Note:

• Running the supply cord through the hand will often detect internal damage.

(d) For portable outlet devices, check that the warning indicating the maximum load to be connected to the device is intact and legible.

(e) Check that any controls are in good working order i.e. they are secure, aligned and appropriately identified.

(f) Check that covers, guards and the like are secured in the manner intended by the manufacturer or supplier.

(g) Check that safety facilities and devices are in good working order.

(h) Check that ventilation inlets and exhausts are unobstructed.
