for 6 cables runs.

• 19mm heavy gauge conduit
Length from main board of 5HP motor starter = 1+1+3+1 = 6.0m
Length from main board to 3HP motor starter = 1+1+5.5+1=8.5m
Length from main board to ½ HP motor base = 1+1+8+1+1.5+1.5=14m

Length from main board to 1HP motor base = 1+1+10.5+1+1.5+1.5=16.5
Total = 45.0m
10% wastages = 4.5m
Total length = 49.5m,(Take 50M)

Length from meter to main switch = 0.75
Length from 5 HP motor starter to 5HP motor base(1.5+1.5) = 3.0 m
Length from 3HP motor Starter to motor base = 3.0m
