Is there any issue combining different wire sizes in same conduit? It is same wire type. XHHW. Thanks.

Why do you think there is a problem? Something brought this up.Is there any issue combining different wire sizes in same conduit? It is same wire type. XHHW. Thanks.
how so ?Well I'm just confused.
I guess I don't understand the statement "different size PHASE conductor for different circuits." I'm not getting a visual as to what this means.how so ?
A 20 amp and a 30 amp circuit in the same conduit, for example. Assuming no derating for more than 3 CCC or upsizing for VD, that would give you #12 and #10 in the same conduit.I guess I don't understand the statement "different size PHASE conductor for different circuits."

The OP has probably asked this question before and the answer can be found in 300.3(C)(1). It can be multiple circuits from the same system, it can also be something like a 480V MWBC and a 208V MWBC. The answer can also be found in 250.122(C).A 20 amp and a 30 amp circuit in the same conduit, for example. Assuming no derating for more than 3 CCC or upsizing for VD, that would give you #12 and #10 in the same conduit.
