Copper and Aluminum in same circuit

Hi, everyone. I'm doing a 200A service upgrade. I have 4/0 aluminum going from the meter box to the weatherhead. I was planning on using 3/0 copper from the meter box to the panel (thinner, better-conducting easier to fish). The individual at the local supplier said that I couldn't do that (per code) -- that the entire circuit had to be either copper or aluminum but not both. That doesn't seem right to me. I'm not making any direct connections between aluminum and copper -- only to the service and load lugs of the meter box, respectively. Who's right?

Thanks,

Fred

That's a new one in my book.

Answer: Yes, you can do as you intend.

I have no idea where he came up with this idea. It doesn't even seem like a logical local code amendment.
