Tech Tips: How To Test Snow Melting Mats and Slab Heating Cable

In this video, our tech lead Scott shows you how to test a snow melting or slab heating system with a mega-ohmmeter.

Whenever you order a snow melting or slab heating cable, you should always test it to make sure it's in good working condition. The way to test these mats and cable is to use an electronic megaohmmeter. Each mat and cable needs to be individually tested. The megaohmmeter tests the insulation between the electricity carrying wires to the ground wire.

Each cable and mat should be tested as shown before, during and after installation.
