The weight a ceiling bracket can hold depends on the type of bracket and where it is placed. A solid metal bracket secured into a ceiling joist can hold quite a lot of weight. A smaller, weaker bracket or one that is secured only into sheet rock should only hold about a pound. A bracket that expands after installation should be used when not securing to a joist for heavier loads. Otherwise, the bracket may break or pull through the sheetrock. Check the bracket packaging for weight limits on the bracket itself.

If you're referring to 14 gauge steel wire, about 60-65 pounds safely, but remember, supported weight depends not only on the wire, but the screws and nails that are attached to the object and the wall or ceiling. (Not to mention the material of the wall or ceiling. Drywall will hold much less than hardwood, so use a stud finder if possible to drill/nail into the wall or ceiling for added support) When in doubt, always use stronger, thicker materials than you think you'll need.

If there's any question about whether or not a drywall anchor will hold on the ceiling, the best thing to do would be to find a ceiling joist and use a long screw to go into solid wood. (Use a stud finder to locate the joist.) Hanging on a ceiling is more dangerous than hanging on a wall since things that fall can fall on people or pets. If you HAVE to hang just in drywall, use the strongest anchor you can get (i.e. one that expands like a butterfly after insertion, or the type that flares out like a flower when you tighten it). Your local hardware store can help with what's a reasonable weight limit.
