3. HEALTH AND SAFETY

Strictly followed as per the manufacturer’s Health and Safety recommendations for handling and use of the materials.
Ensure all involved personnel shall be aware of the same.
Specific safety measures have to follow as applicable, and all the safety measures are covered separately in the project safety plan.

4. OPERATION

Material:
Material used will be as approved by the Engineer.
The sizes and routes routing will be as per the approved Shop Drawings.
Storage and Protection:
Deliver components parts to site, completely identified in accordance with shop and certified CAD Drawings prepared for this work.
Store in accordance with the manufacturer’s instructions, above ground, properly protected from the weather and construction activities.

5. INSTALLATION and fixation

Pre-Installation:
- All materials and documentation relevant to this particular section of works will be checked and verified ensuring that these are correct and approved type.

Prior to the commencement of works, ensure that the areas for permanent installation are ready, accessible and in suitable condition.

Excavation:
No wiring be carried out until the appropriate tests required or in the electrical testing section have been done and the consultant has given his clearance for wiring to commence.
A loop in form of wiring shall be used as far as practicable or unless otherwise indicated. Joints in conductors shall be made using insulated terminal blocks complying with requirements of this specification.
At expansion joints adequate slack shall be left in the cable.
Where Conduits are installed for wiring by others, a draw wire shall be provided between each draw in position.
Where three-phase circuits comprising single-core cables are installed in trunking, all cables of a shall be tied together at intervals not exceeding 200mm.
Cables forming part of alarm, control, communication or monitoring circuits shall have identification sleeves at their terminations. Identification shall be consistent with the relevant wiring diagrams.

Pulling:
Make sure that all conduits and boxes in both ends are free from

damages and blockages etc and installation is approved.

Blockage shall be checked by inserting the draw wire and checking

that it reaches to the other end without any disturbance.

Once the conduit is not blocked the wires shall be pulled using the

draw wires while ensuring no damage occurs while pulling.

Pulling compound or lubricant shall be used for pulling the wires

where required.

Use soap based pulling compound for short runs i.e. less than 20

meters for semi conductive insulated wires.

Use wax based pulling compound for the runs greater than 20

meters for semi conductive insulated wires.

While pulling the wires care should be taken to not insert the pull tension greater than the manufacturer allowed limits.

Termination::
Erect scaffolding where required as per the site requirements.
Cable rollers shall be placed under the cable during pulling over

longer distances and standoff rollers for acute bends, to ensure that

the cable is pulled with minimum effort and the cable outer jacket is

free of scouring lines.

The cable shall be pulled by using pulling means such as fish tape, rope and basket weave wire/cable grips so as not to damage cable or its containment system. Care will be taken to ensure that the maximum pulling tension of all the cables is not exceeded at any time.
Cable should be free of any static load i.e. to be places side by side parallel on the cable tray or ladders. Any kind of dead weight on the cable shall be avoided.
The cables shall be secured to the containment system using approved cable ties for horizontal runs and cable cleats for vertical

runs.

Termination shall be done by using the approved termination

materials that include glands, lugs and other accessories part of

termination kit, by using proper crimping tools. Matching colour gland sheaths shall be provided.

Commissioning:
Set the Meggar meter to 1000 volts DC for cables and 500 volts DC for wires.
Take reading between phase, phase and neutral, phase and earth neutral and earth.
Note that resistance reading must not exceed 2 megaohms(MΩ).
Check and record the resistance readings as per specification on

the approved insulation resistance test forms.

Technical Assistance:
The installation supervising technician for the system trade shall instruct the CONSULTANT Engineer, and Construction Site Manager on the programming and correct operation of the system after the installation is completed.
This instruction shall be scheduled at the convenience of the staff.
All such instruction shall be properly recorded.
WIR will be issued for Consultant approval upon making sure that the installation of the system equipment’s done as per approved shopdrawings and specs and manufacturer recommendations.
