Snow Melting Accessories Description

In order to stay compliant with National Electric Code 426-13, WarmlyYours’ Snow Melt Plaque must be purchased and installed in coordination with a snow-melting system. The code states that embedded snow-melting equipment must be evident by the posting of appropriate caution signs or markings where clearly visible. Thus, this durable cast brass plaque can be easily installed in concrete or asphalt to indicate that the snow-melting equipment is located underneath the material. The plaque is 4” x 4” x 3/8” thick and includes a ¼” diameter x 2” long bolt and nut combination for anchoring.

When installing outdoor WarmlyYours snow melting cables for your driveway, patio, walkway, terrace, stairs, ramp, etc. - NEVER cross, overlap, or allow the heating cables to touch each other. Doing so will quickly cause a circuit failure due to excessive heat build up. Always follow the installation instructions and/or design layout plan to ensure the cable is installed with the correct spacing required for proper operation.

Yes. The manufacturer's splice that connects the heating element to the cold lead should be entirely embedded in a noncombustible material (like asphalt, concrete, or mortar) within the outdoor surface that is being heated.

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.

To ensure optimal performance, snow melting heating elements should be installed so that they are consistently 2"-3" from the finished surface. For installations using pavers, the maximum thickness for pavers installed over heating elements is 2.5".
