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.


Rather than ask around why, I went looking online, and found out the
thermal protective device on recessed lights is set to 194F (90C).
