Brandon Whitmore Posted January 20, 2010 Report Posted January 20, 2010 http://www.nfpa.org/assets/files//PDF/R ... Report.pdf I know I've read this before, but can't recall whether it's ever been posted. Plus, some newbies to the site may not have seen it.
Billy_Bob Posted January 20, 2010 Report Posted January 20, 2010 I see in section "8.0 Luminaires", they pulled off a few old light fixtures and found the crumbling insulation / bare wires! And then you get that in a bathroom along with a combo metal medicine cabinet / light fixture, and not good to say the least. (The heat from the bulbs wrecks the old wiring insulation. Even with a wall mounted light fixture.) And if you leave the fixture in place, I assume the insulation mostly stays in place? But unscrew the fixture and pull it out, then all the insulation crumbles off of the wires.
Jack Davenport Posted January 20, 2010 Report Posted January 20, 2010 That is a pretty scary report isn't it ? As far as the luminaires and the insulation on the wiring, Thats why the manufactures install a label listing the maximum wattage bulb. Yes a 100 watt bulb will work in a fixture rated for 60, but in the long run it is damageing the wiring behind that fixture. Fixtures with the box above it are the worst as Heat rises.
Brandon Whitmore Posted January 20, 2010 Author Report Posted January 20, 2010 I had a question a while back in which I asked whether old BX (AC) cable could be used as a ground when updating from 2 to 3 prong receptacle outlets. This report answered my question. To be safe, I'll continue to recommend GFCI protection in older homes. It's a bummer there's no report such as this where older breakers and panels have been tested by an authoritative source. Heck, they wouldn't even name manufacturers in this report.
