  • SCOPE

    1 Scope

    1.1 These requirements cover radiant heating panels and heating panel sets, for use on ac supply system voltages not exceeding 600 V, designed for installation indoors in nonhazardous locations in household, commercial, and industrial applications, in accordance with Article 424, Part IX , of the National Electrical Code, ANSI/NFPA 70.


    1.1 revised October 14, 2011

    1.2 These requirements cover products designed to be permanently connected to a supply circuit, and that are intended to form an integral part of the building construction after on-site assembly, installation, and connection.

    1.3 These requirements do not cover electric heating equipment or appliances that are covered by individual requirements that are separate from this Standard. Other related standards include :

    a)    Electrical Resistance Heat Tracing for Commercial and Industrial Applications, UL 515;

    b)    Fixed and Location-Dedicated Electric Room Heaters, UL 2021;

    c)    Movable and Wall- or Ceiling-Hung Electric Room Heaters, UL 1278;

    d)    Outline of Investigation for Mobile Home Pipe Heating Cables, Subject 1462 ;

    e)    Outline of Investigation for Roof and Gutter De-Icing Cable Units, Subject 1588 ;

    f)    Electric Space Heating Cables, UL 1673;

    g)    Outline of Investigation for Residential Pipe Heating Cables, Subject 2049; and

    h)    Electric Heating Appliances, UL 499.


    1.3 revised October 14, 2011

    1.4 These requirements do not cover the following:

    a)    Heating equipment connected to the supply by use of a flexible cord with attachment plug;

    b)    Heating equipment that is movable after installation;

    c)    Heating equipment with integral means of producing air flow;

    d)    Heating equipment manufactured and sold as an integral part of a floor or ceiling covering materials such as heated floor tiles, heated carpet, and heated laminate floor;

    e)    Heating equipment exceeding 355 W/m2 (33 W/ft2) when installed in concrete or poured masonry;

    f)    Electric Space-Heating Cables of Article 424 Part V of the National Electrical Code, ANSI/NFPA 70;

    g)    Heating panels and panel sets for mounted directly underfloor coverings in accordance with 424.99 of the National Electrical Code, ANSI/NFPA 70; and

    h)    Radiant heating panels intended to be installed in a dropped or suspended ceiling.

    1.5 These requirements do not cover switches, transformers, power supplies, controls (e.g. temperature) or protective devices (e.g. ground fault protection) that are typically installed separate from the heating panels but may be installed at the same time as part of the space heating system. Those devices are covered by individual requirements that are separate from this Standard.
