Generally, the self-regulating heat trace cable has variable wattage/heat output, the constant wattage heat tracing cable provide constant heat output. The constant wattage heating cable is used for higher temperature applications. The constant wattage cable provides a longer circuit length comparing to the self-regulating heating cable. The self-regulating heating cable has a higher inrush current. generally the SR heat trace cable can have water proof jacketing, the self regulating cable can be placed inside water lines, gutters and downspouts.
