The electrical power portion of most buildings will include
metering, switchgear and distribution panels. A
Construction Supervisor should have a basic understanding
of what these elements do. The metering allows the power
company to keep track of how much electricity gets used.
The largest amount of electricity used at one time (the
Demand) and the power factor also are important on
buildings that have more inductive loads like motors.
Then a main breaker will be required in the switchgear,
allowing the entire electrical system to be turned off.
From this main breaker, the current flows through circuit
breaker panels and sub-panels. Typically a one line diagram
shows the general concept of the electrical power system
and includes metering, switchgear and panels.

Answer / sakthivel

metering
meter is a electrical apparatus it measure the
electrical parameter just like votage ,current energy etc..
switchgear
switchgear is a main importent electrical power control
switch it working depents on voltage, current sence
apparatus
panels
panels are electrical meters and switch gear fixing
coboard with use electrical rule.
