I just had a Luxaire TCGD 30S41S3A 2-1/2 ton aire conditioner installed.
The minimum circuit ampacity is 14.7 amps and the maximum overcurrent device amps is 25 amps.
The minimum overcurrent device amps is 15 amps. The technician who installed the unit told me to change the fuses to either 25 or 30 amps at 250 volts ac. I can purchase 25 amps or 30 amps CRN time delay fuses type D rated at 250VAC, 10KA I.R.

I am a Engineering Technologist and have voltage experience working on dc or ac voltages, so I am aware of the safety. I do not work on live equipement.

So my question is should I buy the 25 amp or 30 amp fuse?
