AL feeder connect to CU bus bar

[anbm]

Thought incoming AL wires that feeds an electrical panel won't work well with CU bus bar, the bus bar must be dual rate (AL/CU).
Or bus bar can be CU but wire lugs must be dual rate (AL/CU)?

Only the lugs must be suitable for the conductor type.

The AL wires are connected to the lugs. If the lugs are suitable for AL you are good.

Not all lugs that are compatible with aluminum are made of aluminum.
