I don't think so....Michael15956 said:Glenn,
314.27(B) allows outlet boxes to support luminaires up to 50 pounds.
314.27(A)Boxes at Luminaire (Lighting Fixture)
Outlets. Boxes used at luminaire (lighting fixture) or lampholder outlets shall be designed for the purpose. At every outlet used exclusively for lighting, the box shall be designed or installed so that a luminaire (lighting fixture) may be attached.
Exception: A wall-mounted luminaire (fixture) weighing not more than 3 kg (6 lb) shall be permitted to be supported on other boxes or plaster rings that are secured to other boxes, provided the luminaire (fixture) or its supporting yoke is secured to the box with no fewer than two No. 6 or larger screws.
IMHO, an "old work" box was NEVER designed to support a fixture....let alone a 50# monstrosity with madison bars or OWCs ....314.27(A) will allow a fixture up to 6#'s, however ....that doesn't mean I like it, but it's "code".Device boxes are designed for the mounting of snap switches, receptacles, and other devices, usually with 6-32 screws (No. 6 screws with 32 threads per inch). Generally, device boxes are not suitable for supporting other than lightweight wall-mounted luminaires. The exception to 314.27(A) permits luminaires such as wall-bracket types or sconces weighing less than 6 lb to be supported by a device box using No. 6 or larger screws. For heavier or ceiling-mounted lighting luminaires, see 410.16, Means of Support. The outlet box is required to provide ?adequate? support
*********(B) Maximum Luminaire (Fixture) Weight.
Outlet boxes or fittings installed as required by 314.23 shall be permitted to support luminaires (lighting fixtures) weighing 23 kg (50 lb) or less. A luminaire (lighting fixture) that weighs more than 23 kg (50 lb) shall be supported independently of the outlet box unless the outlet box is listed for the weight to be supported.
http://aifittings.com/whnew95.htmInstalling an ?old work? box? Our new device box SAVES TIME because it installs with a 3.25" hole saw! Plus, its saw teeth cut a path for the device screws and hold the device firmly in place.
[*]For devices and sconce fixtures up to 3 lbs[*]Large volume; 17 cubic inches*Requires standard maxi plate for receptacles
