A. NOTES
1.2 Test method 2 (CPC terminated at the switch panel and using the phase conductor as a return lead)
1.2.1 Connect the phase conductor (phase wire) to the CPC conductor (earth wire) at the switch panel.
1.2.2 Test between the phase and earth of the circuit at the DB.
1.2.3 Record the test result obtained.
1.2.4 The readings should be compared with the "Resistance of copper conductors" table for a particular length
and size.
2.2 Test method (CPC conductor terminated at the last point of the circuit)
2.2.1 Test between the phase (join together all phase conductors at the switch panel) and the neutral at the DB.
2.2.2 Repeat the test for phase to CPC.
2.2.3 Test between the neutral and the CPC at the DB.
2.2.4 A value of less than 100MΩ on a final circuit is to be unacceptably low and require further investigation.
This Record Of Continuity and Insulation Resistance Test form shall be used for the reporting on the condition of Ring Final Circuit
Wiring only for New Installation before final connection of the switches, sockets, electrical accessories, fittings and DB.

A. NOTES
3.0 For Ring Final Circuits, Regulations 612.2.2 of BS7671:2008 calls for the continuity of EACH live conductor (phase
and neutral) and the protective conductor to be verified.
B. TEST PROCEDURES
2.0 CONFIRMATION OF RING FINAL CIRCUIT IS WIRED IN A RING (4 ends joined method)
2.1 Phase and neutral conductors cross-connected.
2.1.1 Connect the outgoing phase (P1) conductor to the returning neutral (N2) conductor. (P1 to N2)
2.1.2 Connect the returning phase (P2) conductor to the outgoing neutral (N1) conductor. (P2 to N1)
2.1.3 Measure the resistance across (P1 to N2) and (P2 to N1) and record the reading.
2.1.4 Measure the resistance at each socket on the ring between phase & neutral.
2.1.5 If the readings obtained from those Sockets wired into the ring are all the same and equal to the resistance
across (P1 to N2) and (P2 to N1) then the ring final circuit is confirmed.
2.1.6 If the readings are different, this will indicate the presence of a bridge or maybe due to incorrect
connections of the ends of the ring.
2.1.7 If they are connected P1 to N1 and P2 to N2 then the readings will increase or decrease as successive
measurements round the ring are taken.
This Record of Insulation Resistance and Continuity Test form shall be used for the reporting on the condition of three phase points,
Submain Cables, Armoured Cables and Street Lighting Cables.

D. REMARKS
NOTES:
1. Regulation 612.6 of BS7671 : 2008 calls for a polarity test to be carried out to establish that :
1.1 All fuses, circuit breakers and single pole switches are connected in the phase conductor only.
1.2 The centre contact of Edison Screw (ES) lampholders are connected to the phase conductor.
1.3 The polarity of socket outlets, other accessories and points of utilisation (eg luminaires) is correct.
2. The polarity of all circuits must be verified before connection to the supply.
3. Polarity testing must be carried with the supply isolated from the installation.
5. Of all of the above ways, the visual check is usually the easiest and this test is one that is best carried out by the person
installing and terminating cables, rather than by the 'test technicians.

A. NOTES
1. This Test Form is for RCCB, without time-delayed operation to IEC 61008.
2. This Test Form is to be used for testing a two (2) POLE-RCCBs and NOT applicable for four (4) POLE RCCBs.
4. The RCCB should be tested with the load switch off or the load disconnected from the circuit.
