Self-Regulating Heating Cable for Roof & Gutter De-icing
Fine Korea GRXF Series Pre-assembled self-regulating heating cable are designed for residential Roof & Gutter De-icing applications.
GRXF Series are avaliable up to 175 ft lengths(54M), and each comes assembled with a 3.3ft(1M) or 5.9ft(1.8M) power cord and plug. GRXF Series are ideal for smaller jobs such as roof/gutter deicing on porches and overhangs.
GRXF Series generates heat by a material of semi-conductor, showing a characteristic of PTC (Positive Temperature Coefficient).
It produces more heat if the temperature drops and less heat if the temperature rises.

GROUND-FAULT PROTECTION
To minimize the danger of fire from sustained electrical arcing if the heating cable is damaged or improperly installed, and to comply with the requirements of Fine Korea, agency certifications, and national electrical codes, 30-mA equipment or 5-mA personnel ground-fault protection must be used on each SRFF SERIES heating cable branch circuit. Arcing may not be stopped by conventional circuit protection.
