Formulae & Notes
Group A:
Cable = (2 × 3) + (1 × 1.5) = 7.50 m
Cable with 5% wastage = 7.50 × 1.05 = 7.88 m/point
Conduit = 2.50 × 1.05 = 2.63 m/point
Group B:
Cable = (2 × 4) + (1 × 2) = 10.00 m
Cable with 5% wastage = 10.00 × 1.05 = 10.50 m/point
Conduit = 3.50 × 1.05 = 3.68 m/point
Group C:
Cable = (2 × 5) + (1 × 2.5) = 12.50 m
Cable with 5% wastage = 12.50 × 1.05 = 13.15 m/point
Conduit = 4.50 × 1.05 = 4.73 m/point
Total Quantity Formula:
Total Cable = Cable Quantity per Point × Number of Points
Total Conduit = Conduit Quantity per Point × Number of Points
Group A:
Cable = (2 × 3) + (1 × 1.5) = 7.50 m
Cable with 5% wastage = 7.50 × 1.05 = 7.88 m/point

Cable with 5% wastage = 12.50 × 1.05 = 13.15 m/point
Conduit = 4.50 × 1.05 = 4.73 m/point
Total Quantity Formula:
Total Cable = Cable Quantity per Point × Number of Points
Total Conduit = Conduit Quantity per Point × Number of Points
Note:
- Cable quantity includes 5% wastage.
- PVC conduit quantity includes 5% wastage.
- Cable considered is 1.5 sq. mm ISI marked, FRLS/HFFR PVC insulated, single-core copper conductor cable.
- Conduit considered is 20 mm dia. ISI marked PVC conduit.
- The calculated quantity is based on the standard Group A, Group B and Group C point-wiring arrangement.
