Temperature ratings for wire

[Anonymous]

I was getting ready to replace an overhead light fixture in my kitchen, when I read the following warning sticker on the back of the new fixture:

" For supply connections, use wire rated for at least 90 degrees C. Warning - risk of fire. Most dwellings built before 1985 have supply wire rated for 60 degrees C. Consult a qualified electrician before installing"

I have consulted my basic wiring book and my most recent box of wire from the home improvement store, and none refer to temperatures of the wire. I didn't find anything useful at the UL site. My house was built in the 70's. Have you run into this situation before? Any information would be appreciated.

Thanks-

You hit a subject that has many varying opinions exact opposite of each other. This same subject appeared in the recent past on a previous post by another seeking the same quest.

You will find an interesting set of replies with at least three and maybe four differing views from very respected people who help with replies in this and other forums. Each of their views were respected and given credit for the strength and validity of their stances. Good reading. REad the following link that may help you. Suspect you will end up calling your local AHJ [authority having jurisdiction] electrical inspector to get a final ruling to protect yourself but that link is very educational from several differring views of qualified people who replied to that forum question. It was asked on this forum about a month ago.
