SECTION 14
INSPECTION AND TESTING
1401 Every installation shall, on completion and before being energized, be inspected, tested and approved by
MEW Inspector in accordance with this section. All necessary application forms and other details as stipulated shall
be submitted to the MEW prior to testing the installation.
1402 A visual inspection shall be made to verify that the installed equipment and installation methods are in
accordance with the approved drawings. The MEW Inspector will also ensure that there is no damage to any part of
the installation.
1403 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
Labeling of circuits, switches, etc.
1404 The MEW Inspector shall carry out insulation resistance test and earth continuity test. Insulation resistance
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 in corporating 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) mega ohm.
1405 Earth continuity test shall be carried out between the consumer earthing terminal and the remote end of earth
continuity conductors. The resistance value obtained shall not exceed those stated in clause No.607.
1406 The MEW Inspector shall also carryout appropriate test to ensure efficient and correct operation of all earth
leakage circuit breakers and other protective devices.
1407 The contractor shall obtain a test certificate from MEW 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 the MEW Inspector Is to witness these test only and certify the test certificates,
three copies of which will be prepared, one for retention by MEW
1408 The MEW Inspector shall carry out measurements to determine the earth electrode resistance 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 consumer.
1409 Any alternation to the existing installation shall also be inspected and approved by MEW Inspector.
