Did you turn the AC Blower on high? Was the Condensor fan also off?
AC fuse blowing

AC Blower was on high- Cabin squirrel-cage fan
Condensor fan was on
Compressor was off
No fuse blowing and I was using red fuse

Go to the guy who installed it?
Since the Compressor is new, you didn't have any issues before, then the Compressor sounds like it could be the issue. The electrical part of the compressor is the clutch that activates the compressor. Make sure the wiring to the compressor isn't shorting to ground.
Thanks for all the help, including your call @sfdon. AC now is running well and reaching 48 on a 85 degree day using red fuse. Here was the fix:
Cleaned all electrical connectors and the fuse box. Removed the front panel and treated both the temperature control knob (which was very stiff) and the A/C fan control knob with contact cleaner, followed by a small amount of DeoxIT.
Checked the squirrel fan from both sides, and it spun freely, no obstructions. The squirrel fan is still always running (just barely) even though switch is fully off.

It should not run at all, with power going to it then the heater fan should not be able run, does it?
Squirrel fan runs all the time with every off. Maybe replace the AC fan switch? Not a major problem just a bit annoying when cold out
But does heater fan also work?
1- Squirrel fan turns on when key is in on position, and also when you start the car
2- Heater fan can be turned on by moving main on/off blower switch to the right, although it does not stay in the high position, I think the cable needs adjusting. It will go to high but as soon as I let go of the lever it goes to medium speed

You have a crossed wire somewhere. The changeover relay above your fuse blocks locks out the heater fan if the a/c fan is turned on.
