Cables shall be dressed properly, secure cables to cable tray using UV protected heavy duty cable tie or SS cable tie. Ensure that the cable distance is maintained as per the approved drawings.
Shall be observed the cable insulation shall not be damaged during pulling.
Grounding cable shall be laid parallel along with the low voltage cable.
The cable shall be kept inside a barricade for avoiding any damages during the installation of pump.
On the completion of the cable laying and dressing continuity and insulation resistance test shall be carried out and shall be recorded with the witness of Quality personnel.
Cable end shall be sealed properly till the glanding and termination.
