Hello,

I am installing a recessed light in the kitchen.

The box says the wire must be rated to 90° C (as opposed to 60° C).

The kitchen lights are wired with standard NMB 12/3.

Is this acceptable? I don't see the temp rating on the wire.

Also, would 14/3 NMB be acceptable?

Thanks in advance.

Purely for informational purposes.

I asked why do most fixtures require 90C wires? I found out many
manufactures use very thin fixture wire(18awg) which will heat up
beyond 60C wire specs with their amperage. This means anything coming
in contact with the fixture wire, under the wire nut, needs to be
protected to 90C.

In this case, NM-B contains 90C conductors (some even list themselves
as 105C conductors). So I wouldn't have to do anything different to
wire in your type of fictures.

IMHO: If you feel in anyway you cannot perform the work safely, then
you need to get a qualified person.
