If the box is made to support a fan, it will say so somewhere on the inside
of the box, it will also have 10-32 threaded holes instead of 8-32 which
you'll find on a standard ceiling outlet box

I'm trying to install a ceiling fan in our breakfast nook. I removed
the light fixture it previously had (it's a somewhat heavy ugly pendant
light). The junction box looks different from what I've seen in the
bedrooms. I have installed ceiling fans in all the bedrooms. I
remembered the builder said that we could install fans in all our
bedrooms by removing the ceiling light.

In the breakfast nook after I removed the light, the junction box
looked a bit different from the junction boxes I've seen in bedroom
ceilings. how to figure out whether this one is strong enough to hold a
fan (52" fan, it's a large kitchen and nook). do junction boxes have
any ratings on them that I can look up on the web to see if they can
hold a fan?

Thanks.
