I have to disagree.

2002 Article 100
Equipment. A general term including material, fittings, devices, appliances, luminaires (fixtures), apparatus, and the like used as a part of, or in connection with, an electrical installation.

Your opinion is that a junction box is not 'material used in connection with an electrical installation'?

Of course this Article 100 definition means that a raceway is also equipment.

Does this mean a raceway in a concrete slab must have sufficient access and working space? ;)

Section 110.26 leaves room for many interpretations. :p

Bob,
Section 110.26 leaves room for many interpretations.

It sure does. The wording in 110.26(A), if applied as written, prohibits the installation of the receptacles that are required by 210.52(C). The code panel refuses to address the serious wording problems in this section even though there have been numerous proposals submitted.

Re: Old panel used as juction box

Since this thread was about using an old panel as a junction box, I would like to know if this violates the UL listing of the panel.
Since it is not listed as a junction box is it legal?
I know we have all done this in a retrofit job.
What do you do with the cover? Do you replace it with a new sheet metal cover (not listed)?
I have pop riveted the door closed and labeled it a junction box.
Or should the can be removed and a listed JB be installed?
 
Re: Old panel used as juction box

I do not find a general requirement for junction boxes to be listed.

Of course the fact I did not find one does not prove it is not there. :D

312.8 Enclosures for Switches or Overcurrent Devices.
Enclosures for switches or overcurrent devices shall not be used as junction boxes, auxiliary gutters, or raceways for conductors feeding through or tapping off to other switches or overcurrent devices, unless adequate space for this purpose is provided. The conductors shall not fill the wiring space at any cross section to more than 40 percent of the cross-sectional area of the space, and the conductors, splices, and taps shall not fill the wiring space at any cross section to more than 75 percent of the cross-sectional area of that space.

I would say that removing the overcurrent devices leaves adequate space for splices.

I sure would not count on this interpretation though. :D

most places in Bay area accept door of panel screwed shut for acceptance as j box, plenty of room in most panels.

The enclosure that a panelboard is installed in is covered by Article 312. I see no reason why you can't remove the "panel" and use the cabinet as a junction box.
