As the names imply, constant wattage cable uses fixed wattage output per linear foot and does not automatically adjust in response to temperature changes. Self-regulating cable is manufactured with a resistance matrix placed between its 2 buss wires that varies the ohms resistance per linear foot to automatically adjust in response to temperature changes. Learn more about this in our blog Self-Regulating vs. Constant Wattage Heating Cables.

Self Regulating cable is not designed for snow load removal. It is designed for deicing in scuppers, roof overhangs, gutters, downspouts, trench drains, etc.
