D2.11.3 D2.1 1.3 Inspection Inspection & T Tests ests D2.11.3.1 Inspection & T Testing esting Procedures Procedures
Every installation shall, before being energised, energised, be inspected and tested to verify that requirements have been met. The methods of test shall be such as to ensure that no danger or damage can occur even if the circuit is defective. The tests shall be carried out in the following sequence. D2.11.3.2 D2.1 1.3.2 Vis Visual ual Inspe Inspection ction
A detailed inspection inspection shall precede testing and should be carried out with the section of the Works under inspection disconnected from the supply. The detai detailed led ins inspe pecti ction on sh shall all con confir firm m that that the Works Works ha have ve been been instal installed led in accordance with the design and include, but not be limited to, verification that: Equipment complies with the specified standards, has been properly selected and erected and is not visibly damaged or defective so as to impair safety, and that adequate access has been provided. Conductors have been routed in safe zones or are mechanically protected, and that connections have been correctly made and identified. Protection against direct and indirect contact has been provided. Appropriate isolating and switching devices have been provided and that protective Appropriate and monitoring devices have been appropriately chosen and set. Identification labelling has been properly provided for circuits, switches, fuses and terminals, and that operating diagrams and instructions, together with danger and warning notices, are in place. The main earth grid resistance is less than 4 . D2.11.3.3 Continuity of Protective Conductors
Every Ever y pro protecti tective ve cond conductor uctor shall be tested tested from the distribut distribution ion switchgea switchgearr earth earth terminal to the remote end of the protective conductor to verify electrical soundness and proper connection.
The resistance measured shall not exceed 0.5
when
subject to a 500 V test supply.
D2.11.3.4 D2.11. 3.4 Continuity of Ring circuit circuit conductors conductors
The continuity of all conductors shall be tested, including the protective conductor of every ring circuit. The resistance measured shall not exceed 0.5 D2.11.3.5 D2.1 1.3.5 Insul Insulation ation Resistanc Resistancee
when
subject to a 500 V test supply.
Insulation resistances resistances shall be measure measured d between phases, phase to neutral, phase to earth and neutral to earth for all circuits. Insulation shall have a resistance of not less than 0.5 M between poles or to earth when subject to a 500 V test supply. D2.11.3.6 D2.1 1.3.6 Polar Polarity ity
It shall be verified that: Single pole Single pole swi switch tches, es, fus fuses es and and circui circuitt br brea eaker kers s ar are e conne connecte cted d to the ph phase ase conductor only. The outer contacts of lamp holders are connected to the neutral, not the phase, conductor. Wiring has been properly connected to socket outlets. D2.11.3.7 D2.1 1.3.7 Earth faul faultt Loop Impedance Impedance
Circuit phase to earth loop impedances shall be measured. A test to ensure a safe measure of earth bonding shall be carried out before any phase-earth loop impedance test is undertaken. Maximum Maxim um val value ues s of circui circuitt earth earth fault fault loo loop p imped impedanc ances es shall shall be as given given in BS 7671/IEC60 364 for different disconnecting protective devices. D2.11.3.8 D2.11. 3.8 Operation of Residual Current Current Devices
The The effe effecti ctiven veness ess of RCDs RCDs shall shall be tested tested by simula simulatin ting g an ap appr propr opriat iate e fault fault condition, independently of any test facility incorporated in the device.
