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

• Installation:

• Free standing LV Switchgears / Motor Control Center
• Check the cable trenches and supports are painted and ready for permanent installation of the said equipment.
• Move the panels from the storage area to their designated room. Fully crated switchgear or panels shipped on a timber sub-base shall be lifted under the subbase.
• When moving the fully crated panels from the storage area to the switchgear room using fork lifts, the mast must be as close as possible to the face of the crate and forks must be fully projected under the crate. Lift the fully crated switchgear squarely.
• Uncrate, unpack and remove the switchgear from its timber base. Care must be taken to protect the panels from unnecessary scratches or bents on the panels.
• Move in the switchgear using steel pipe rollers to its final location. Care must be taken to ensure that the panel does not over balanced while being moved to its final locations.
• Align the panels horizontally and vertically.
• Join switchgear section. Jointing of section must be done under the direct supervision of the manufacturer representative and shall be done in accordance to their standards. Ensure that the busbars are properly aligned and shall be tight as per manufacturer recommended torque setting.
• Secure the switchgear assembly and ensure that it is fixed properly on its base.
• Remove all unused bolts, nuts, washers and clean the panel. Panel side covers and doors shall be put back. Ensuring that it is properly tightened.
• Conduct insulation resistance test on the switchgear to ensure that all joints are properly insulated.
• Raise Request for Inspection for switchgear installation.
• Conduct on-site testing on the equipment such as insulation test, Di-electric test at 2.5kV for the LV switchgear, CT ratio test and simulation test for protection and relay setting in accordance to manufacturer recommendation and project specification. Test shall be witnessed and sign-off by the Consultant.
• After all the testing has been successfully sign-off and accepted by the Consultant, cable dressing and termination will commence.

• Wall-mounted Sub-main Distribution Board / Distribution Boards / Motor Control Panel
• Check the location where in the panel boards are installed were accessible and ready for permanent work installation.
• Mark the location of the panel on the wall. Wall-mounted panels shall be installed 1800mm A.F.F.L. from the top of the panel.
• Install the uni-strut channel supports on the walls. Make sure that the support is rigidly and securely fixed.
• Fix the panel on the supports. Ensure that the panel are rigidly fixed in its supports and vertically and horizontally aligned.
• Remove unnecessary foreign materials and unused bolts, nut and washer inside the panel. Fix panel cover and protect with plastic sheet.
• Raise Request for Inspection for panel installation.
• Conduct on-site test on the panel such as insulation resistance test and simulation test for controls and protection relays in accordance to project specification and manufacturer’s recommendation and the test shall be witnessed and signed-off by the Consultant.
• Dress and terminate properly the wires and cables inside the panels.:

• 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 shop drawings, approved specs and manufacturer recommendations.
