SECTION 11: INSPECTION AND TESTING

 SECTION 11

 INSPECTION AND TESTING

1101      Every installation shall, on completion and before being energised, be inspected, tested and approved by EDD's Inspector in accordance with this section. All necessary application forms and other details as stipulated shall be submitted to the EDD prior to testing the installation.

1102      A visual inspection shall be made to verify that the installed equipment and installation methods are in accordance with the approved drawings. The EDD's Inspector will also ensure that there is no damage to any part of the installation.

1103      Visual inspection shall also be carried out to ensure satisfactory and approved methods are adopted for the following.

• Connection of conductors
• Identification of conductors
• Connection of single pole devices in phase conductor only
• Correct connection of socket outlets and lamp holders
• Presence of fire barriers and protection against thermal effects
• Method of protection against direct contact including measurement of distances
• Labelling of circuits, switches, etc.

1104     The E.D.D. Inspector shall carry out insulation rأ©sistance test and earth continuity test.  Insulation rأ©sistance test in large buildings may be divided into groups of outlets, each containing around 50 outlets.  An outlet shall include every point and every switch except that a socket outlet incorporating a switch shall be regarded as one outlet.  A 500 volts D.C. supply shall be applied to the installation and the insulation resistance obtained shall not be less than one (1) megohm.

1105     Earth continuity test shall be carried out between the consumer earthing terminal and the remote end of earth continuity conductors.  The rأ©sistance value obtained shall not exceed those stated in clause no. 607.

1106     The E.D.D. Inspector shall also carry out appropriate tests to ensure efficient and correct operation of all earth leakage circuit breakers and other protective devices.

1107     The contractors shall obtain a test certificate from E.D.D. ensuring that all control and safety devices are tested prior to the usage of the electric water heaters.  All tests shall be carried out by the contractor, who must record the cut out, cut in temperatures and the fluid pressure at which the mechanical safety valve operates and resets.

NOTE:  The role of E.D.D. Inspector is to witness these test only and certify the test certificates, three copies of which will be prepared, one for retention by E.D.D.

1108     The E.D.D. Inspector shall carry out measurements to determine the earth electrode rأ©sistance by approved methods and all necessary assistance required for carrying out this test other than the testing apparatus and auxiliary electrodes shall be provided by the contractor.

1109      Any alteration to the existing installation shall also be inspected and approved by E.D.D. Inspector.
