We were tasked to create a single line diagram design:

Given:

a $.$ # HP ACU

b $.$ # HP Squirrel Cage Induction Motor

c$.$ # HP ACU

d$.$ # HP Squirrel Cage Induction Motor

Task:

Each motor has its own branch circuit $(4$ total$)$ with its own individual breaker

then a and b will be combined and have its own circuit breaker

breaker and c and d will also be combined to have another circuit breaker

then from the $2$ wires, a main circuit breaker will be placed. Total of $7$ circuit breaker.

Help me determine the process on how to size the conductors in each circuit breaker and how to size the circuit breakers. Inverse time circuit breakers will be used. Base the solution from the Philippine Electrical Code $1.$ Section numbers and Table numbers will be useful
