POWER FLOW FROM T3

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 design

Greater safety

Easy estimation of cost

Ease for accessing power

No overheating and fire protection

Highly efficient and reliable

Easier maintenance
