I've read and believe that a belt gives your abs something to press against. Therefore increasing the amount of intra abdominal pressure. As a result there is increased core/lower back/ab support (as opposed to not wearing a belt). This is how I believe Rippetoe explains it, this is how I've seen others explain it.
How do you know when do you need one? I am of the opinion that you need one when you are squatting or deadlifting heavy enough that you feel you need the extra support. And I am of the opinion that when it will be needed will be different for everyone.
Rippetoe also explains that the whole idea that your core or abs strengthen harder/faster/better without a belt as opposed to with a belt is untrue.
I'm just explaining what I've read and what my opinion is. I use the belt on my heavy squat and deadlift sets because it makes sense to me to do so. It may or may not be the same for someone else.
