Any electricians or handy folks here? Wall sconce question.
Hello Fellow Veneers!
Pole room is coming along… tomorrow baseboards and flooring will be done! That means bye bye ceiling fan and hello pole!!!
I figured while I was busy preparing the room, I should replace the sconce too.
The new sconce instructions and packaging say "MIN 75 C Supply Conductors". Can anyone tell me how I determine if my wiring is at least 75 C? I do not know how to determine what rating the supply conductor is.

If you can pull the wiring out far enough, the rating should be stamped on the plastic sheathing. You can also check somewhere that the wiring is exposed, like an attic or crawl space. There's a chance the wiring in the attic is a different rating than the wiring at the fixture itself, though, so beware of that. Most builders will use the same wiring throughout the house, but a previous homeowner could have switched it out. You know- stuff happens.

Thank you RidgePole, I will see if I can pull it out to find the sheathing. I appreciate you letting me know, I figured it would have to be printed somewhere! If I'm unable to tell from the inside… I'll return the fixture. I avoid the attic, too much insulation, too dark and spiders. https://stage.studioveena.com/img/smilies/icon_eek.gif
Thanks!!!

It’s good that you noticed the “MIN 75°C supply conductors” note before installing the sconce. That rating is about the heat tolerance of the wiring insulation. Many modern homes already use NM-B wiring, which is rated for 90°C, but if your house is older, it may still have NM (60°C) wiring. Pulling the conductor out far enough to read the markings, as RidgePole mentioned, is the safest way to confirm. If you can’t locate the stamp and don’t want to poke around the attic, another option is to have a licensed electrician check it for you. When I had a fixture upgraded a while back, my wiring turned out to be fine, but the peace of mind from getting it inspected was worth it.
Since you’re making changes for your pole room, it might be a good time to have an expert look over the electrical setup, especially with new lighting involved. A local service such as: https://www.electriciansingapore.org/ can handle these inspections and installations safely, and they’ll confirm whether your current conductors meet the sconce requirements.
That way, you won’t have to second-guess whether the wiring is suitable, and you’ll know your new fixture is both safe and compliant.
