Notes:
• Table shows maximum allowable length of submersible cable for the given full load current
where site voltage is normal ie 415 V
• For other voltages, the cable size is to be selected for the length which is calculated as follows.
• Calculated length = (415 / Actual voltage) x Actual length
• 7.5 HP and above are SD motors. For these motors, the actual current is 1/√3 the FL current
• The cable size and maximum allowable length are arrived at accordingly
