Line Side Splice

[BLarsen1964]

Morning guys--
I've got a situation where aluminum cables (3C #500 w/#2/0 Gnd) have been pulled to a control panel from a 600A bus plug (480V).
The rocket scientists have noticed a label at the termination bussing stating "Copper conductors only."
Is it acceptable to splice the aluminum conductors in the control panel using terminal blocks (600A+ rating) to transition to copper conductors?

 

[jim dungar]

Yes.
The termination must be made using copper conductors.

 

[BLarsen1964]

Yes.
The termination must be made using copper conductors.

Agree-- but the question is--"can you splice the line side conductors to transition to copper conductors using terminal blocks?"

Yes.
There are several different splicing methods, it is your choice.

Yes.
