Frequently Asked Questions
Our self-regulating heating product is designed to be cut to length at the jobsite by an installer where it can then be end-capped with accessories (sold separately).
However, our constant wattage kits contain heating elements that cannot be shortened or altered in any way.
GFEP is the National Electric Code (NEC) required protection for fixed outdoor deicing and snow-melting equipment, which may be accomplished by using circuit breakers equipped with ground-fault equipment protection (GFEP) of 30 mA. It is important to understand that this required equipment protection is NOT the same as a 5 mA GFCI used for personal protection.
Cable length needed depends on the sizes and areas of the roof that need to be deiced (roof with gutter, downspouts, valleys, and/or dormers). Our best recommendation is for you to give us a call (1-800-875-5285) and we can help you identify what measurements will need to be taken. Alternatively, you can
measure the dimensions of the aforementioned areas and refer to the installation manual to get an idea of how much cable you'll need.
