Splices within Light fixtures

[osaengineers]

What kind of temperature and voltage rating for wiring nuts for splices within a fixture?. (The fixture is indoors, has 2-T8 High output lamps(each 44watts), electronic ballast, 120V )
Thanks

There should be a notation in the instruction sheet or on a label in the fixture as to the temp rating. Voltage rating for most 120 volt apps is usually 600 volts. Common sense should dictate that the rating of the insulation should exceed the voltage of the supply. In the real world I have connected such fixtures with 90C NMS and a good brand of wire nuts (no tape!) with no problem. I prefer Ideals but 3Ms are OK too. Dollar store wire nuts are usually junk and probably aren't UL listed. Most important is to use the correct connector for the wiring where the feed comes into the fixture. I have seen where no connectors were used on fluorescent lights and vibration from the factory caused the sharp edges to cut into the insulation and energize the metal on the fixture causing employees to get poked when they touched the fixtures. In one shop this oversight along with an open neutral caused the metal on a 120 volt fixture to become energized at 190 volts.

Typically, wire nuts have a 105?C and 600v rating.

If you are concerned, Ideal has a simple 150 deg, wirenut:

I use to use them in HPS fixtures where I experienced melt down of
scotch-loks.
