in an industrical wiring, why we are using lighting DB and Power DB separately?..

In an industries, they are using different load. If we are
using single DB for lighting and power means, the variation
of load when we are using will affect the input voltage.

The lighting load is the uniform load and small. But the
power load will varry according the usage. For better
maintanence both DB's are provide separately and providing
the separate size of input cables.

Answer / lijesh p k

In an industry,various loads are used for various
purposes.Lighting loads are usually small and UNIFORM.But
in the case power loads they vary as per the usage which
may affect the input voltage.So to safeguard against faults
and for easy maintenance different DB's are used for
lihgting and power in industrial wiring.
