Mike, the 800W heater # XH27FR draws about 6.8 amps running, with a 13.5A inrush on startup. Xtreme recommends a 20A breaker for this model. If you’re wiring it into your breaker panel, give it its own dedicated circuit to avoid overloads. You can definitely just plug it into an outlet as is though.
Are you planning to mount it permanently, or use the quick-release bracket for seasonal swaps?
