main bars are those bars which lying on the shorter span :
main bar formulas :
Long span divide by distance of main bars puls one = Long span/distance of main bars
+1
main bar lenght= (short span+hooks)-C.C C.C= concrete cover
Distribution bars which is those lying on the longer span:
No's=long span divided distance of main bar plus one=long span/distance of main bar+1
distribution bar length =(short span +hooks) -C.C c.c = is concrete cover

Advantages of ring main distribution system?
The main advantage of Ring distribution over Radial is that it gives the user a greater security of supply. You will notice that all the distribution bus bars on the ring are supplied at both ends of the ring. This means that if a fault develops on any part of the ring or on an isolator or circuit breaker, then this device can be isolated and, even with the ring completely broken, the electricity supply will continue to be fed to the bus bars from one end only. The supply to the user is maintained and, with the fault isolated, it can be repaired before the ring being switched back on.
