BUS BAR SYSTEM

Power from utility meter is brought to each floor by means of bus duct or bus risers.•Advantages of bus bar system over normal cabling system are as follows: Saving in space and cost.Increased flexibility in designGreater safetyEasy estimation of costEase for accessing powerNo overheating and fire protectionHighly efficient and reliableEasier maintenance
