What would you like to know?

Where would you need three 4/0, one 3/0 and one #6? Doesn't make any sense.

Just telling us what the conductor size is doesn't help us. We need the type of insulation on the wire to let you know.

For example for more than 2 conductors in a size 2 schedule 40 conduit you cannot go above 1.316 sq. inches. Using your sizes and type "THWN-2" insulation, the fill would be 1.4997 sq. inches. Meaning the conductor is to small for these cables. A size 2.5 schedule 40 conductor should have been used.

If your electrician used a different type of cables, the sizes will be different! The trade size 2 may be correct for the different type conductors. So don't raise hell with the guy until you have the correct information. The sizing information can be found in Chapter 9 of the NEC, Use table 4 for the conduit measurements and table 5 to determine the conductor sizes based on the type and AWG of the conductors.
