What does it mean when the low side a/c line sweats?

It is very wet and almost dripping. Is this normal or could it mean the system is perhaps over or under charged?

Normal. You should also see an evaporator condensation drip under the car.

Yep. Just means it’s hot out, and the line is cold, and moisture is condensing on it out of the air.

Cooler air is more dense and contain the same level of moisture as warm air. So when warm meets cold, the water condenses on the pipe, windows, etc.
