I have to put in a new service wire I was Given service wire that was told was ok. they said it was 4/0 aluminum. I looked at the jacket and it said, 3 cdr awg 2 compact al. aluminaflex. I am putting in a 200 amp meter. The wire has 2 insulated wires and and 1 non insulated. I am not a electrician im just trying to hang it all and have a electrician come in and do the final part. Is the wire I have ok to use?
