AL to CU wire splice box

[Charles Smith]

Aluminum to copper wire splicing in ceiling box.
Did not use COPALUM adapters and pigtail adapters at oultets.

panel /splicing updated in 1994 remodel.

Was COPLUM available in 1994.

Was this the "accepted" method in 1994?

[Jim Port]

That split bolt is not listed to be used that way. They are for two conductors. It would also need to be listed for use with AL and Cu.
