Gwz,

1956 NEC 4113 is todays 2002 NEC 410.6.

Quote
410.6 Luminaires (Fixtures) Over Combustible Material.
Lampholders installed over highly combustible material shall be of the unswitched type. Unless an individual switch is provided for each luminaire (fixture), lampholders shall be located at least 2.5 m (8 ft) above the floor or shall be located or guarded so that the lamps cannot be readily removed or damaged.

NEC Handbook commentary:
Quote
Section 410.6 refers to pendants and fixed lighting equipment installed above highly combustible material. If the lamp cannot be located out of reach, the requirement can be met by equipping the lamp with a suitable guard. Section 410.6 does not apply to portable lamps.

I find the section use of "lampholder" while pointing to "luminaire" interesting.

4156. LAMPHOLDERS,SCREW-SHELL TYPE. Lampholders of the screw-shell type shall be installed for use as lampholders only.


At one time, wall-mounted 'receptacles' for serving portable appliances had traditional edison-base screw shells. You could literally screw a lamp into a wall-mounted receptacle. The one I have seen in an older house had a brass, hinged cover to save unintentionally contacting live conductors.

There's an open-bulb lampholder in my closet here, (I DID NOT INSTALL THIS!). I keep a small 7.5W light in it (the medium based one), plus I barely use it anyways. so I dunno. was pondering CFL

A keyless lampholder is not a luminaire??? Then what is it? As far as I know, it's a luminaire- of a type specifically banned from closets. Where does the "not a luminaire" come from?

Otherwise- on this subject, I accept the challenge, and shall submit a better illustration of why lamps in closets might be a hazard...stay tuned :-)

Has anyone else seen an old (Disney???) cartoon where a cat-and-mouse chase is going on; the mouse of course runs into the baseboard mouse hole and the cat heads right into an UNCOVERED Edison-base receptacle in the baseboard!

Ya gotta wonder how many babies were shocked/electrocuted with those...

Oops, sorry for the threadjack!

No wire bias here- I'm standing on neutral ground.

Here is a pic that shows why hot lightbulbs and closets don't go together....

And for those who don't believe in Murphy's Law....yes, I had to access a basement hatch that was under all this stuff! :-)

Thanks for the clarification that "keyless" lampholders are only proscribed from clothes closets- and may be used most anywhere else.

Yeah. That was Tom & Jerry, an MGM cartoon.
