Char-Broil Electric Grill Blue - See description

I've had this for two years and now all of a sudden, when in use, it trips my circuit breaker and shuts off. I tried two outlets and the same thing happened. I think my wiring is not capable with the unit, or there is something wrong with the heating element in the grill, which I'm not trained to know or fix. Either way, if you think your outlet will work or you can find a way to fix this, please take it off my hands. I paid $250 for it two years ago, but given what I said above, there is an enormous markdown. Comes with used cover, as pictured. Pick up only near Wrigley Field.
