Hi, I am installing a new meter base, 100 amp panel, and re-locating the laundry room.
I ran 100 amp 4 gauge? wire from the meter (underground) to the panel. I used 2" conduit where it comes out of the trench and into the house, and into the panel.
My question is, can I put other wires in the conduit with the 4 gauge? It would end up with the 3 conductors for the panel and a 12 gauge 2 conductor wire, and a 10 gauge 3 conductor wire.
This will get inspected and I want to get it right the first time.
Thanks in advance!

Is this a just a meter you are starting at or is it a combo meter load center?

#4 wire is only good for 65 amps and this is unfused conductors you can't run anything else in there from your meter.

Table 310.15(B)(7) allows for #4 CU wire for a 100 amp service or #2 AL.

OP. Never try to pull cables into conduit. The 2" PVC conduit is plenty big enough. But you are never going to pull anything else over the wires you already pulled unless you are willing to sacrifice one of them..
Why would you need more wires in the service lateral anyway? You cannot feed the structure with more than one service/supply.
Why not be a bit more specific as to why you would want to add any wires to this service conduit.

I was hoping to come back out of the panel with 2 circuits to feed my laundry (from the outside). I was hoping to put them back out the conduit that the #2 wires are in to save piping in more conduit.
The #2 wires are in a 2" conduit, which I believe is bigger than necessary.
Sorry for the confusion, it makes sense looking at it, but hard to explain.

Okay. The wire us #2 aluminum. It is fused at the meter with a 100 amp breaker.
Once you pass the first disconnect you must go to a four wire feed with grounding at the disconnect and your building.

Table 310.15(B)(7) allows for #4 CU wire for a 100 amp service or #2 AL.

Since this is past his first disconnect I don't think 310.15(B)(7) would apply here. And a four wire feed would be required.
