Alum. Wire in condo- - stove has copper wire - when changing stove see blue wire nuts... No good. Went to electric supply and they sold me Morris esr250s Aluminum splicers/reducers said better than the wire nuts?. said need to tape up and put back in box... are these OK?. neighbor was questioning them.

Thanks Steve

Go to the Morris website. Claim the spicer products are ANSI approved for AL-AL or AL-CU connections.
