What temp does sugar start to burn?

[Grant Y]

Can someone give me an idea on what temps I can expect to see sugar start to burn on my spareribs?

I'm doing my first rib cook at 275 this weekend. I've always done ribs at 225 and I generally go heavy on brown sugar so I'm concerned I'm going to scorch the rub.

I've read that turbinado sugar will give me a bit of a cushion, but how much should I expect?

Thanks

This page has some good info on the various stages of sugar as it's heated. Looks like 350*F is the point at which it burns. Looks like color develops starting around 300*F.
