How do you determine the size of a distribution board?

How do you determine the size of a distribution board?

Size of MCB for Branch Circuit-7:

  1. Load Current of A.C= (No X Watt X Demand Factor)/Volt =(1X3000X0.
  2. Branch Circuit-7 Current as per NEC = Non Continues Load+125% Continues Load.
  3. Branch Circuit-7 Current as per NEC =(7.83)+125%(0) =7.83Amp.
  4. Type of Load=Heating & Cooling Type.
  5. Class of MCB=C Class.
  6. Size of MCB=16 Amp.

What size subpanel do I need?

To calculate the breaker size, simply divide the adjusted wattage by 240 volts to find the rated amperage needed for your subpanel. and you can simply round up to the next higher size of ​the breaker. For example, if the load calculation comes out to 48 amps, you should use a 50-amp breaker to protect the circuit.

How to calculate the MCB rating of a DB?

Below is how I did the calculation for the rating of the main MCB of the DB, I = 50.2 x 1000/1.73x400x0.8 (Pf) = 90.8A I therefore wanted to use 110A MCB and some combinations of 32A, 16A, 10A, 6A for distribution. Please criticise and advice. Also shed more light on how to select the maximum number of breakers for distribution.
