I am building a new 24 sq m bachelor's pad. my query is about the electricity requirements...First, only 5 CFLs, six 2-gang outlets, and 1 outlet for 1.5hp aircon...

Now, what is the size of the electrical wires (THHN) to use for the 5 switches? for the six 2-gang outlets? and also for the 1.5hp aircon? Would THHN #12 be sufficient?

For the circuit breakers- should I use 15 amperes or 20 amperes for the 5 switches? a separate 15 or 20 amperes for the six 2-gang outlets? and what about for the 1.5hp aircon, 30 or 40 amperes?

I am not familiar with these...and I appreciate anyone who could help me here...TIA
