1. While designing the distributor voltage drop calculation is important.
2. Voltage drop in distribution system should be maintained within permissible limit ( ±6%).
3. Layout should be simple in design.
4. It should have less initial cost
5. Make the distribution system with minimum distribution losses.
6. From safety point of view distribution system should maintain proper clearances.
7. Select the cross section of conductor from the result of load densities present & future.
8. While selecting cross section of conductor P.F. of the load should be consider.
9. Power should be available to consumers whenever needed.
10. A steady, non-fluctuating, quality supply (Pure sine wave) should be available to consumers.
11. Distribution system should not be over loaded.
12. Distribution system lay out should not affect the appearance of locality.
13. Before installation of distribution system proposed widening of the road in the near future are to be kept in mind
14. Fault on nearest distribution system should not affect stability of existing distribution system.
