Testing and Commissioning Procedure forElectrical Installation

1. Introduction

The procedures stated in this document cover the activities in preliminary tests andinspections, functional performance tests and the commissioning of newly completedinstallations and existing ones after major alteration. They are so compiled to facilitatethe work of Project Building Services Engineer (PBSE) and Project Building ServicesInspector (PBSI) in the following aspects with respect to testing and commissioning(T&C):

(i) To vet and approve the T&C procedures proposed and submitted by theContractor;

(ii) To witness those T&C procedures as specified; and

(iii) To accept the T&C certificates and other supporting data.

The Contractor shall carry out the T & C works as detailed in this document.Supplementary T&C plans may be proposed by the Contractor as appropriate andagreed by PBSE, e.g. for special equipment supplied and/or installed by the Contractor.

The administrative requirements for T & C works are in general as specified in thelatest General Specification for Electrical Installation (the General Specification) issuedby the Building Services Branch of the Architectural Services Department. If there isany discrepancy between this procedure and the General Specification, the GeneralSpecification shall take precedence.

“Major Alteration” of an existing electrical installation means alteration involving workon any distribution board or electrical equipment having an electrical current ratingexceeding 100A single phase or 60A three phases in an existing electrical installation.

This procedure is also intended to lay down the minimum testing and commissioningrequirements to be carried out by the Contractor on a new Low Voltage CubicleSwitchboard Installation upon completion or on an existing Low Voltage CubicleSwitchboard Installation after a major alteration involving modification of the mainbusbar such as upgrading, reposition and extension.

2. Objectives of the Testing and Commissioning (T&C) Works

The objectives of the T & C works are:

(i) To verify proper functioning of the equipment/system after installation; and

(ii) To verify that the performance of the installed equipment/systems meet withthe specified design intent through a series of tests and adjustments.

(iii) To capture and record performance data of the whole installation as thebaseline for future operation and maintenance.

of 21EE_TCP

2007 Edition

For the avoidance of doubt, depending on the specific demands of individualinstallation, the PBSE may require additional or substitute T & C works in regard to anyelements in the installation other than those indicated in this Procedure.

3. Scope of the Testing and Commissioning (T&C) Works

3.1 Preliminary Steps for Testing and Commissioning

Before carrying out T&C, the Contractor shall take the following steps:

(a) Submit draft T&C procedures to the PBSE for approval. The draftT&C procedures shall include essential procedures mentioned in thisprocedure plus additional T&C procedures required for specificinstallations as well as manufacturer’s recommendation;

(b) Obtain design drawings and specifications and to be thoroughlyacquainted with the design intent;

3.4 Functional Performance Tests

The purpose of functional performance tests is to demonstrate that theequipment/installation can meet the functional and performance requirementsas specified in the General/Particular Specifications. Functional performancetest should proceed from the testing of individual components to the testing ofdifferent systems in the installation.

The Contractor may have to make temporary modifications as the testproceeds. The specific tests required and the order of tests will vary dependingon the type and size of systems, number of systems, sequence of construction,interface with other installations, relationship with the building elements andother specific requirements as indicated in the General/ParticularSpecifications. The testing of systems may have to be carried out in stagesdepending on the progress of work or as proposed by the Contractor.

Part of the tests may be required to be carried out in suppliers’ premises inaccordance with the provisions in the General/Particular Specification.

Any performance deficiencies revealed during the functional performance testsmust be evaluated to determine the cause and whether they are part of thecontractual obligations. After completion of the necessary corrective measures,the Contractor shall repeat the tests.

If any test cannot be completed because of circumstances that are beyond thecontrol of the Contractor, it shall be properly documented and reported to thePBSE, who shall then liaise with the relevant parties to resolve the situation.The Contractor shall resume his testing work immediately upon the attainmentof a suitable testing environment.

3.5 Documentation and Deliverables

The Contractor shall submit his proposed T&C procedures together with theTesting and Commissioning Progress Chart shown in Annex I to Annex IV,where applicable, to PBSE for approval.

All inspection and T&C results shall be recorded by the Contractor in theappropriate test record forms, the reference of which is shown against eachindividual test. Sample of these forms can be found in Annex I and Annex III.

of 21EE_TCP

2007 Edition

installation /equipment as installed is correctly selected and erected inaccordance with the COP Code 21A and COP Appendix 13, and thatthere is no apparent damage. The visual inspection shall include acheck on the following items, where appropriate:

(a) Adequacy of working space, access, and maintenancefacilities;

of 21EE_TCP

2007 Edition

(r) Erection method; and

(s) Any other appropriate inspection as listed in COP Appendix13.

4.2.2 Sequence of Tests

The following items, where relevant, are to be tested preferably in thesequence indicated below:

(a) Continuity of protective conductors, including main andsupplementary equipotential bonding,

(b) Continuity of ring final circuit conductors,

(c) Insulation resistance,

(d) Polarity,

(e) Earth electrode resistance,

(f) Earth fault loop impendance,

(g) Functions of all protective devices,

(h) Functions of all items of equipment.

In the event of any test indicating failure to comply, that test and thosepreceding, the results of which may have been influenced by the faultindicated, shall be repeated after the fault has been rectified.

4.2.3 Conductor Continuity

(a) Continuity of Protective Conductors

The test shall be in accordance with COP Code 21B (3).

Every protective conductor, including all conductors and anyextraneous conductive parts used for equipotential bondingshould be tested for continuity. The test should be made byconnecting together the neutral and protective conductors atthe mains position and checking between earth and neutral atevery outlet by a continuity tester, which should show areading near zero.

(b) Continuity of Ring Final Circuit


The ring circuit should be tested from the distribution board.

of 21EE_TCP

2007 Edition

The ends of the two cables forming the phase conductorshould be separated, and a continuity test should show areading near zero between the two; the same tests to be madebetween the two cables that form the neutral conductor, andbetween the two cables that form the protective conductor.

The testing method in above paragraph is only applicablewhen the ring circuit has been inspected throughout, prior tothe test, to ascertain that no interconnection (multi-loops)exists on the ring circuit. Otherwise, the testing methodsstipulated in Part 3 of the Guidance Note 3 to BS7671, shouldbe adopted instead.

4.2.4 Insulation Resistance


A suitable direct current (d.c.) insulation tester should be used tomeasure insulation resistance. Care should be taken to ensure that theinsulation of the equipment under test could withstand the test voltagewithout damage.

To carry out this test, it is acceptable to divide large installation intosections with groups of outlets, each group containing not less than 50outlets. The term outlet in this case includes every point andevery switch. A socket outlet or appliance or luminaire incorporating aswitch is regarded as one outlet.

When measured with all fuse links in place, all switches and circuitbreakers (including, if practicable, the main switch) closed and allpoles or phases of the wiring electrically connected together, theinsulation resistance to earth should not be less than the appropriatevalues given in Table 21 (1) of COP. For best practice, the insulationresistance shall not be lower than 1.0 mega ohm for low voltageinstallation under a test voltage of d.c. 500V.

When measured between all conductors connected to any one phase orpole of the supply and, in turn, all conductors connected to each otherphase or pole, the insulation resistance should not be less than theappropriate values in Table 21(1) of COP. For best practice, theinsulation resistance shall not be lower than 1.0 mega ohm for lowvoltage installation under a test voltage of d.c. 500V.

For the sake of enhanced safety, when the value of insulationresistance measured is near the minimum values as required in thisT&C procedure, or at a relatively low valves where consideredabnormal to trade’s practice, the concerned circuit /installation shall bere-checked to improve and re-test shall be conducted afterward.

In carrying out the test:

of 21EE_TCP

2007 Edition

(a) wherever practicable, all lamps should be removed and allcurrent using equipment should be disconnected and all localswitches controlling lamps or other equipment should beclosed;

(b) where the removal of lamps and/or the disconnection ofcurrent using equipment is impracticable, the local switchescontrolling such lamps and/or equipment should be open;

(c) electronic devices connected in the installation should beisolated or short circuited where appropriate so that they arenot damaged by the test voltage.

(d) where the circuits contain voltage sensitive devices, the testshould measure the insulation resistance to earth with all liveconductors (including the neutral) connected together.

The sequence of test shall be as follows:

(1) Main switch/switchboard and outgoing circuits with sub-mainswitches being isolated;

(2) Sub-main switches/switchboards and outgoing circuits withfinal circuits boards being isolated; and

(3) Final circuit boards and final circuits.

Where equipment is disconnected for the test and the equipment hasexposed conductive parts require to be connected to protectiveconductors, the insulation resistance between the exposed conductiveparts and all live parts of the equipment should be measured separatelyand should have a minimum insulation resistance not less than 0.5MegaOhm.

For Site Built Assemblies, the insulation applied to the live parts ofthe assemblies for protection against direct contact shall be tested withan applied voltage equivalent to that specified in the appropriateRegulation and/ or COP for similar factory-built equipment. Thesupplementary insulation of Site Built Assemblies for protectionagainst indirect contact shall be tested for degree of protection not lessthan IP 2X, and the insulation enclosure shall be tested with an appliedvoltage equivalent to that specified in the appropriate Regulation and/or COP for similar factory-built equipment.

4.2.5 Polarity


A test of polarity should be carried out to verify that:

(a) every fuse and single-pole control and protective device is

of 21EE_TCP

2007 Edition

connected in the phase conductor only,

(b) centre-contact bayonet and Edison-type screw lampholders toIEC 60238 in circuits having an earthed neutral conductor,have their outer or screwed contacts connected to that neutralconductor, and

(c) wiring has been correctly connected to socket outlets andsimilar accessories.

4.2.6 Earth Electrode Resistance


A proper earth electrode resistance tester should be used to measureearth electrode resistance. An alternating current at 50 Hz of a steadyvalue is passed between the earth electrode T and an auxiliary earthelectrode T1 placed at a separation distance recommended by themanufacturer of the tester but in any case should not be less than 20metres away. A second auxiliary earth electrode T2, which may be ametal spike driven into the ground, is then inserted half-way betweenT and T1, and the voltage drop between T and T2, divided by thecurrent flowing between T and T1, gives a measured earth electroderesistance of earth electrode T.

For an electrical installation having four or more earth electrodeswhich are installed more or less in line, following a general directionnot exceeding 15 deviation and with separation between adjacentelectrodes not less than the recommended distance by themanufacturer of the tester but in any case not less than 20 metres,these electrodes can be used in turn as the auxiliary electrodes for thepurpose of measuring the earth electrode resistances.

The following alternative method for measuring the earth electroderesistance may be used if the electricity supply is connected. A loopimpedance tester should be connected between the phase conductor atthe origin of the installation and the earth electrode with the test linkopen, and a test performed. This impedance reading could be treatedas the electrode resistance.

4.2.7 Earth Fault Loop Resistance


The earth fault loop impedance should be measured by a phase-earthloop tester with a scale calibrated in ohms.

The earth fault loop impedance should not exceed the requirements ofCOP Code 11.

Before the test begins, it is essential to establish, by inspection, that

of 21EE_TCP

2007 Edition

the earthing conductor and all relevant earth connections are in place,and that the bonding connection to electricity supplier’s earthingfacilities is disconnected. Measures should be taken, during theimpedance tests especially when the earth leakage protective devicesare effectively removed for the duration of the tests, to ensure that theinstallation is not being used other than by person(s) carrying out thetests.

4.2.8 Functions of All Devices including Protective Devices


Functional Test of Residual Current Device (RCD):

(a) Function of residual current devices should be checked by aresidual current device tester simulating an earth fault inorder to verify its effective operation. The in-built test buttonshould also be tested for proper functioning. One of thetesting methods is specified in subparagraph (b) and (c)below. Other testing methods complying with relevantnational/international standards are also acceptable.

(b) The test should be made on the load side of the RCD betweenthe phase conductor of the protected circuit and the associatedcircuit protective conductor. The load should be disconnectedduring the test.

(c) For general purpose RCDs to IEC 61008 or RCBOs toIEC61009, with a leakage current flowing equivalent to 50%of the rated tripping current of the RCD, the device shouldnot open. When a leakage current is flowing equivalent to100% of the rated tripping current of the RCD, the deviceshould open in less than 300 ms unless it is of Type S (orselective) which incorporates an intentional time delay, whenit should trip within the time range from 130 ms to 500 ms.

Function of other protective devices, such as miniature circuitbreakers, moulded case circuit breakers, air circuit breakers, fusedswitches, switch-fuses and protective relays etc. should be checked byhand operation as appropriate.

Function of all items of equipment such as isolators, switches andindicative devices should be checked by hand operation.

4.2.9 Additional Check for Installation in Hazardous Environment

The following additional check, where appropriate, shall be carried outfor installations in hazardous environment in accordance with COPCode 21B (10):

(a) Where appropriate, the area involved should be checked to

of 21EE_TCP

2007 Edition

ensure ‘gas free’ condition before insulation and earth faultloop impedance test are carried out.

(b) All equipment should be suitably protected according to thetypes of protection under COP Code 15. The integrity of thetype of protection provided for the equipment should not bejeopardised by the method of installation. No alteration thatmay invalidate the conditions of protection can be used.

(c) Equipment should be kept clean and free from accumulationof dust, foreign particles and deleterious substances.Equipment is kept free from condensation.

(d) All lamps, fuses and replaceable parts should be checked sothat correct rating and types are being used.

(e) The surface temperature of all equipment should beappropriate to the type of protection being provided.

4.3 Statutory Inspection and Test for High Voltage Installations

4.3.1 Inspection before Test
