They are for high tempatures, I have used them in commercial kitchen equipment, something like an infra red food warmer above a counter is on place you might find them.

I have had jobs that specked them for all recessed fixtures as well as the aforementioned heat lamps and kitchen equipment.

yup ive used them on heaters for an extruder.

i also found some used in an old farm house, id be scared to say how old they were, id guess maybe from the 20s or 30s.
 
I did not think they made them anymore. The reason I had asked is, I got a couple from and old light fixture in a house wired in K&T. I asked my boss about them and he told me they dont make them anymore,

I'm beginning to worry about you. Maybe you should get out of the house a little more often, see the sun, breath some fresh air, that sort of thing. :D
 
Used them in a theater, all the wire insulation is cloth wrapped rubber and any splices in the fixture had to be made with porcelain nuts, same reason high temp, found this out the hard way after the butt connectors I used melted to the frame and let the blue flames out the back.

Don't waste the thought time! I was taught long ago, "Don't guess, look it up", and that was while a pup. So it's my hang-up.

Fact of fiction, I want to know what I'm dealing with, frankly I thought it was going to lead to clam or oyster shells not farrow pigs.

But what was I thiniking, I failed chemistry... :rolleyes:
 
In the old homes and businesses when I was first starting to do electrical work it was very very common to see porcelin wirenuts throughout. Anywhere there was knob-and-tubing, that's where they could be found.:)
 
I have a box of 500, about the size of a small blue nut. Rated 300 volts to ground.
Somehow they ended up in a box of sutff I got at a yard sale.
