To SG_Jimmy,
Usually 1/2 is good enough for HDB.
3/4 is overkill & ur trunking will be very big.
Class 1 & Class 0 is referring to their heat insulating properties, redundant in aircon matters.
G22 will be better.
16mm is good enough.
Agreed with terumo. if 3/4 then u can see very big trunking in your house.
