Roof and Gutter De-Icing, Self-Regulating, Cut-to-Length. For Residential and Commercial
Applications.
Product Overview
• SR Trace™ cable prevents costly damage to roofs caused by ice
formation and snow accumulation in gutters, downspouts, and
roof valleys.
• The self-regulating heating cable automatically varies its heat
output as the surrounding temperature changes.
Applications
• Suitable for use on asphalt or wood shingles, metal roong or
“membrane” type roong.
• Downspouts that freeze and clog.
Features
• Available for 120 and 240 Vac applications.
— 240 Vac can be used for 208 or 277 Vac applications.
• Power densities of 3, 5, and 8 Watts per foot (0.30 m) at +50°F
(+10 °C ).
• Available in cut-to-order lengths, convenient 250 ft
(76.20 m) self dispensing reel boxes and 750 ft (228.6 m)
master supply reels.
• Manufactured with a waterproof TPE outer jacket.
• Can be installed in dry or wet environments.
• Can be wrapped over itself (overlapped) minimizing the risk of
damaging temperature-sensitive roof coating.
• One year limited warranty.
Related Products
• It is recommended that heating cables for roof and gutter
deicing utilize controls that sense the presence of moisture
and cold-temperature to optimize energy consumption. See

Certied.
Notes
• Per NEC and CEC requirements ALWAYS use a ground fault protection device (GFEP)
to reduce the danger of re from a damaged or improperly installed heating cable.
Electrical fault currents caused by damaged or improperly installed cable MAY NOT
BE LARGE ENOUGH to trip a conventional circuit breaker.
• Heating cables must be installed in compliance with all national, state/provincial and
local codes. Check with your local electrical inspector for specic details.
• Do not twist the bus wires together at either end of the cable.
• All electrical connections in the system should be sealed against moisture.
• Do not expose heating cables to temperatures above their maximum ratings.
• Immediately replace any damaged heating cable or components.
• Classied areas (explosive dust or gas) require the use of special electrical
components.
ROOF AND GUTTER DE-ICING
Illustrated Features
A special self-regulating core is at the center of the SR Trace™ cable. This core is conductive and adjusts according to the surrounding
temperatures. When it is cold, the cable’s core has many conductive paths that generate enough heat to keep the water owing from the
roof to the ground. As the surrounding temperature warms, there are fewer conductive paths and less heat is generated.
