What is the snow melting cable rating?
The WSM (Warmup Snow Melting cable) or WSMM (Warmup Snow Melting Mat) is commonly used in concrete pours, asphalt driveways and paved walkways. All of these Warmup products sold as 240V are rated for 208-240V applications. Mats are 2ft or 3ft wide and with a cable spacing providing 50w/sqft for optimum results under even the harshest conditions. Embedded up to 4” deep, they can be laid out as tire-tracks or for full coverage designs.
