Don't think you will find a bare aluminum wire.
Why were they not all pulled at once?

what kind of conduit?

You probably should have pulled them all at the same time.

Most pulling lube is conductive, is usually says on the bottle to wait until it dries to turn the power on. That being said, I've never had a problem using it in a hot conduit.

Why would there be a problem with a bare ground wire? It would be the same as steel conduit, wouldn't it?

Triplex? What construction?
3 insulated conductors under an overall jacket, 2 insulated wires twisted w/1 uninsulated wire or ????
What did you leave as a pull rope?

justinae, in your other post about this you said you purchased a single #4 Al to go with the #2 Triplex. Why are you not using the #4 for the equipment ground?
Triplex is usually 2 insulated conductors wrapped around a bare AL conductor, it is not recognized as a wiring method by the NEC & is not allowed in conduit, either above or underground, the bare AL will turn to a toothpaste like substance underground, BTW.
Triplex is used by PoCo's for overhead service drops.

The Triplex he got was UD for direct bury.

How long ago did you pull this originally? Yellow 77 gets really sticky when it dries.

Do not put bare conductors/ground in a steel conduit in moist (buried) conditions! The conductor and the conduit will form an electrolytic reaction, resulting in the failure of both. However, the first to fail will be the conduit (steel is sacrificial to aluminum!) and once the conduit fails, then the conductor will quickly deteriorate.
You could perhaps use plastic conduit, but I would not recommend it, as it will be almost impossible to keep it dry, which will result in deterioration of the bare conductor.
PVC conduit.
Pattenp I'm a bit embarrased to say, but the original #4 was a couple feet short. I was able to successfully fish it through after I fished the triplex, so in effect I can use the too short #4 as pull string.
My length is about 15 feet with 2 90 degree elbows.
I'll get the same kind of wire I had, but is it possible to use #6 instead of #4?
thanks

I didn't see where it was installed under ground.

look into codes cause i am not sure if a ground needs to be insulated if in pvc

If he pulled aerial style triplex cable (2 insulated conductors wrapped around a bare AL conductor), the neutral is uninsulated for 240vac 1ph service.
Last I checked it's not kosher to have an uninsulated neutral and an uninsulated ground in the same conduit.... just like not using aerial style triplex cable in conduit.

He pulled Triplex UD. It is for direct bury or can be put in conduit in wet locations. He has another whole post as to what he is using. All is speculation as to what he's doing is just confusing things.

Yes you can use a #6 Al or #8 Cu for the equipment ground. What ever you get make sure it has either THHN/THWN or RHH/RHW-2 rating.
Edit: Since you used AL SER in the house you should stick with AL for the rest of the equipment ground to the garage.

No bare conductors allowed in any type of conduit on this side of the border,all must be insulated.

You can use a #8 THWN (green) insulated copper conductor for the ground.
If the run is 15' of conduit, the wire length can't be much more than 25'.
Cost should around $20 or so.
