Do you install snow-melt cable? There's a new NEC code
WAUCONDA, IL — Delta-Therm Corp., a manufacturer of electric heating systems, recently supplied mineral-insulated (MI) cable for a parking garage application in response to a change in the National Electrical Code (NEC).
MI cable is now the only cable available for snow melting and deicing that is exempt from ground-fault protection when embedded in a noncombustible medium such as concrete or asphalt, the company said.
