10%Wastage = 0.67m

Total = 7.45m, (Take 8.0m)
• 25mm flexible conduit for 5HP&3HP motor (0.75+0.75) =1.5(Take 2M)
Calculate the length of cables
2.0Sq mm copper conductor from main board to 5HP motor terminals = 3(1+1+3+1)+6(1.5+1.5+0.75)40.5m

15%Wastages&end connections = 7.2m
Total = 55.2m, (Take=56.0m)
1.0Sqmm copper conductor from main board to ½ HP motor terminals =2(1+1+8+1+1.5+1.5+0.75)=29.5M
15% wastages & end connections = 7.76m
Total 59.51m, (Take=60.0m)
