20Amp Porcelain Lampholder ?

We have a closet that has no light inside, but there happens to be a junction box inside the closet near the ceiling where some conduit goes upstairs to feed an outlet. The junction box is located in a perfect spot inside the closet to add a porcelain lampholder with a pull-string, adding some much needed lighting to this dark closet. The only thing is this is a 20 amp circuit, and the only lampholders I can find are marked for 15A. It seems like I would risk starting a fire if I put a 15A lampholder on a 20A circuit. Do they make 20A porcelain lampholders?

The 15a socket isn't a problem but you can't use a bare bulb in a closet any more and the lamp holder must be at least 12 iches from any shelves or clothing clothing.

Ray covered the clearance requirements for fixtures in closets, but depending on what that circuit feeds you may not be able to use it either. If you can tell what that circuit feeds we can let you know if other options are available.

Thanks for the responses! The circuit feeds 4 outlets. Does this affect weather or not I can add the porcelain fixture?

If the receptacles are in the kitchen, bathroom, or dining room you can't use the circuit.

Stop, a pocelain bulb holder cannot be used in a closet period.

Ok- It sounds like I *really* shouldn't do it! Can you help me understand why not? Can you suggest an alternative to getting hardwired lighting in a closet like that which could take advantage of the existing circuit? Of the four outlets on the circuit one is in a bedroom an the other three are in the basement.

The code is concerned with combustibles like clothing and boxes coming into contact with a hot bulb and starting a fire.

Article 410 has specific clearance requirements and allowable fixture types in closets. Incandescent types require at least 12" of clearance from the plane of the shelf. Fluorescent lights reduce this clearance to 6".

Installing a light fixture with an enclosed lamp would be pretty easy. You might just need to add a mud ring to the box if it is a 4x4" box. You still have to have the proper clearances as stated above. IF you don't have 12", you could still install a florescent strip light that would allow you 6".

I really appreciate you guys sharing your knowledge!

I measured and, if I were putting a porcelain holder off a mud ring with a normal bulb I'd have about 13 inches from everything in the closet. What constitutes an enclosed lamp? Can you think of a way to get an enclosed incandescent bulb off a mudbox without going more than an inch farther than the porcelin bulb holder rig?

An enclosed lamp would have a glassdome or globe over the bulb. I do not ever remember seeing an enclosed fixture smaller than about 8" in diameter.

I guess I should have been clearer on no bare incandescent bulbs when I wrote it. You could use a fluorescent light fixture. A two tube 2 foot fixture should be enough. Also where are the receptacles on this circuit located. Some circuits regardless of load can not be used for this.

One receptacle is located about 2 feet away from the junction box in question. And the other three are all 10-30 feet away in another room.

A "jelly jar" light might work out for you like this: http://common2.csnimages.com/lf/1/ha...ique+Brass.jpg Google jelly jar light for more options as they also make ones for ceiling mounting.

They are for outside but indoors is ok unless marked outside only.

That's not a bad idea. I ended up going with a florescent fixture because I needed something with a switch (pull chain in this case) built-in..

Thanks everyone!
