On of the lines with the cap on it going to my outdoor AC unit is wet with condensation? Is this normal And what are these two lines?

that meAns your a/c working the one with condensation on it just need some insulation. The isulation doesn't have anything to do with efficiency its just there so you don't get the condensation which could drip on ceiling or floor.

The suction or low pressure line, which is the larger of the two, that returns the refrigerant from the evaporator to the compressor, which then goes into the condenser unit. Should be cold, which can lead to condensation.The smaller, high pressure, supply line, which brings the refrigerant into the the conditioned space, should be warm or hot to the touch.

those are the refrigerant lines. the one from compressor into the house is cold. condensation means you likely need to insulate that line. ask at Home Deport for materials

That's normal. But that line should be wrapped with insulating foam wrap.

Yes it's normal for it to be wet. One line sends refrigerant (what most people incorrectly call "Freon") from the outdoor unit where the condenser coil is, to the evaporator coil located in the inside unit. The other lines returns the refrigerant. The refrigerant is very cold when it comes out of the condenser so it "sweats" like a cold glass of iced tea on a hot humid day.
