SUMMARY

The discussion centers on the design and requirements for a Low Voltage Distribution Board (TGBT) to manage various electrical loads from a 630kVA, 30kV/400V power transformer. The installation includes 17 cooling chambers, a residential building, an employee camp, outdoor lamps, and a water submersible pump. The distribution board must accommodate a main circuit breaker, multiple circuit breakers for each load, and additional spares. Due to safety and liability concerns, professional assistance from a qualified electrician or electrical engineer is strongly recommended.

PREREQUISITES
  • Understanding of Low Voltage Distribution Board (TGBT) design
  • Knowledge of circuit breaker specifications and ratings
  • Familiarity with electrical load calculations
  • Experience with power transformer configurations (630kVA, 30kV/400V)
NEXT STEPS
  • Research circuit breaker selection criteria for various loads
  • Study electrical load calculation methods for residential and commercial applications
  • Learn about safety standards and regulations for electrical installations
  • Explore the role of qualified electricians and electrical engineers in distribution board design
USEFUL FOR

Electrical engineers, electricians, and professionals involved in designing or managing low voltage electrical systems, particularly those working with distribution boards and transformer installations.

Hi, can any one help me with this Low Voltage Distribution Board?
My installation a below :

17 Cooling Chamber
01 Residential building
01 Emplyees Small-Camp
20 Outdoor lamps
01 Water Submersible pump
02 Spares

All theses are supplied from Power Transformer 630kVA - 30kV/400V ( 3P+N )
This distribution board should contains :
01 Main circuit breaker
17 Circuits breakers for each chamber ( 23kW - 62kW / 40A - 105A )
01 Circuit breaker for Residential building ( 2 Floor Standard residential building )
01 Circuit breaker for Employees Small-Camp ( 4 Room, 1 Kitchen, 4 Air Conditioners )
01 Circuit breaker for 20 X Outdoor lamps ( 150W )
01 Circuit breaker for Water Submersible pump ( 6kW )
02 Circuit breakers for Spares
