1 - Power Distribution Panel:

Power distribution panel is used for utilization of equipment. Power supply is received from LT panel and distributed to the outgoing feeders for utilization.

A molded case circuit breaker are used which incomer supply is connected with LT panel and outgoing supply is connected width panel busbar. Many outgoing equipment feeder incoming is connected with panel busbar and feeder outgoing is connected to the equipment.

3 - Important Components of Power Distribution Panel:

1- Metering Section

Measuring meters are used for measuring the system parameters like as volt meter, amp meter, multifunction meter etc.

A- Measuring Meters

Many types meters are used in panel like as Analog meter and digital meters. Amp meter, volt meter, multi function meter, energy meter are used for measuring the parameters. It all can be used digital or Analog as per requirement.

B- Indicators

Indicators are used for knowing the status of panel operation.Difference type indicators are used with different color.

• R Phase.
• Y Phase.
• B Phase.
• MCCB ON.
• MCCB OFF.
• MCCB Trip.

2- Incomer Section:

A- Molded case circuit breaker:

Power distribution panel power supply is received from LT panel. MCCB is used for making and breaking incoming power where ACB incomer supply is connected with LT panel and outgoing is connected with APFC panel busbar.

3- Outgoing or feeder Section

different types feeders are used for outgoing just like as pump, distribution board, Motor, lighting load etc.

Circuit Breaker

MCCB is used for making and breaking power supply in outgoing feeder for equipment. Its capacity may be 100 amp to 800 amp.

Starters

DOL stater or star delta starters are used for controlling te motors, pumps etc.
