During my rough in inspection, the inspector noted some older wires that I had installed in my ceiling canister lights. Some of the older ones are not rated for 90 degrees C. He stated I can determine if they are rated by looking at the coating of the stripped wires. I contacted the mfg’er of some wires that I new were <10 yrs old and this Tech guy said as long as the wire is a “type NM-B” that they would comply.
I contacted the inspector on this and he said “not necessarily”. Can anyone advise on this? Is there any way of determining for sure? Some wires are for sure going to get replaced, but 1 wire that I’ve used quite a bit of is ID’ed as “Essex E18679 Type NM-B 12 CU 2 CDR with Awg.”
