Yes, the Norcold AC Heater 638374 is listed for the Polar N7/N8/N10, which includes your N8XRT, and it's in stock. I can't confirm the exact wattage and amp rating from here.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
