I’m a novice when it comes to electrical. I bought a new LED ceiling light fixture and found a “Min 90 degree supply conductors” warning after opening the box. I read a bit about it but I still don’t quite understand how I would know if this is an issue in my house or not and whether it’s safe to install. My house was built in 1974 so does that mean I automatically have the wrong wiring to support the new fixture? Would I need to go to my breaker box and look at the wiring?
Thanks in advance, Dave.
