Page 7





Wires & cables installed in the trunking for each circuit, sub circuit or final sub circuit shall be tied together at regular intervals.

8.5.

OUT DOOR CABLE INSTALLATION  Pulling cables in underground duct conduits.  The underground duct conduits installation will be “NEC Installation standard” wiring requirement. The underground conduit should be following approved shop drawing, approved material submittal and project specification.  After underground duct installation inspection, shall be closed both side of the underground duct conduit for cleaned and protect from dust or water dampness.  The number and size of cables drawn in to a particular underground duct conduit shall not exceed that allowed in specifications.  Use pulling compound or lubricant where necessary.

8.6.

METHOD OF TERMINATION OF WIRES & CABLES  When satisfactory pre-termination inspections and tests have been carried out, works will commence in the appropriate areas.  The cable has been inspected and tested to ensure it is in accordance with the contract specifications.  The cable support and fixing system have been checked to ensure it is complete.  The arrangement at the termination point will be checked to ensure that there is adequate space to allow termination to take place.  Only materials that are recommended by the cable manufacturer will be used for termination.  No reduction in the number of strands of a cable core will take place at a cable joint or termination.  Connectors & Splicers: All wiring shall be terminated with crimped tinned copper lugs suitable for the receiving terminal. Units of size, current rating, material, type and class suitable for service indicated. Select to comply with the project’s installation requirements. Splices in building circuit wiring between devices are not allowed. Splices are allowed in junction boxes.  Conductors of cross sectional area greater than 10mm2 will be terminated using compression type lugs in conjunction with bolted terminals. The compression type lugs will be compressed using a manufacturer approved compressed tool.  The gland plates will be fitted with removable glands to allow the cables to be laid into and removed from the box without the need to thread through the gland entry. The glands will be fitted with an internal earthing stud and an armor clamp. It will be located directly below the corresponding cable connection of the center phase.

  

All joints and terminations in power cables will be made by certified cable splicers or jointers inspected without objection by the consultant. All termination has taken place all cable boxes enclosures will be vacuum cleaned to ensure that all cable cuttings, dirt and debris is removed. Before energizing any part of the electrical distribution system takes place, all functional testing will be completed, all terminations will be checked and secure, all covers and safety shields will be in place.

9. INSPECTION AND RECORD   

 

 



When installation has been completed, WCT shall raise INR for installation inspection with installation checklist to be approved by client. INR should be backed up with test reports, method of statement and approved drawings. After installation of conductors and cables and before electrical circuitry has been energized, demonstrate product capability and compliance with requirement. Perform each visual and mechanical inspection and electrical test stated in NETA Acceptance Testing Specification. Certify comply with test parameters. After substantial completion, but not more than 60 days after final acceptance, perform an infra-red scan of each splice in cables and conductors 25mm2 and larger. Remove box and equipment covers, so splices are acceptable to portable scanner. Correct malfunctioning products at site where possible and retest to demonstrate compliance, otherwise remove and replace with new units and retest. Type of Wires & Cable testing  Continuity check  Insulation resistance test  Phase polarity test Test Reports; Prepare a written report to record the following  Test procedures used  Test results that comply with requirements  Test results that do not comply with requirements and corrective action taken to achieve compliance with requirements

10. HSE REQUIREMENT 10.1.

ENVIRONMENT HEALTH AND SAFETY (ESH) The followings will be considered while installing the system:  Material handling (moving material around site).  Damage of material  Working at height.  Trips and falls  Cutting materials  Hand injury during cutting  Falls from height  Materials falling from heights  Bending Cables

SAFETY MEASURES The Measures to be taken are as following:                

10.3.

All PPE shall be used. Use safety working platform. Power must be inspected prior to use. Establish a clear way to allow for safe movement of cable drums Use mechanical means to move drums When moving drums manually, chocks/stoppers must be in standby to prevent uncontrollable movement. Use cable jacks and rollers to decrease work load. Top step of stepladder must not be used unless designed for that purpose. Ladders must be checked to ensure correct length, type and condition before use The ground base for the ladder must be firm and level. The ladder must be of sufficient length to extend 1m above the step-off point when used as access to scaffold. The correct angle of rest for the ladder is 75 degrees or a base to height ratio of 1:4 Ladders must be secured against slipping by tying at the top and at the bottom Ladder use will be monitored regularly to ensure operators are not overreaching or using two hands to work. Damaged ladders will be broken up or removed from site Stepladders must be used fully open with tight cords.

ENVIRONMENT

To consider the following:  
