UL 1278 STANDARD FOR SAFETY Movable and Wall-or Ceiling-Hung Electric Room Heaters

LOCATION-DEDICATED HEATER – A cord-connected heater that is normally placed in one location for usage such as:
a) Cord-connected wall- or ceiling-mounted heater
b) Freestanding cord-connected heater that exceeds the weight and/or dimension limitations of a movable heater.

LOW-VOLTAGE (SECONDARY) CIRCUIT – A circuit involving a potential of not more than 30 volts altermating-current, (42.4 volt peak or direct-current). and supplied by a primary battery or by a standard Class 2 transformer, or by a combination of transformer and fixed impedance that, as a unit, complies with all the performance requirements for a Class 2 transformer. A circuit derived from a source of supply clasifed as a line voltage circuit, using resistance in series with the supply dircuit as a means of limiting
the voltogc and ourrent, io not concidered to bo a low woltoge nor an isolatod limitod goondary oirouit.

MOVABLE HEATER – A freestanding cord and plug connected heater that does not exceed 65 pounds (29.4 kg) and has no dimension greater than 8 feet (2.4 m). A wall- or ceiling-hung heater which may be used as a movable heater without further guiding or propping, is also considered a movable heater.

PRODUCT ENCLOSURES – Thal part of the product (metallic or nonmtallic) that;
a) Renders inaccessible all or any parts of the equipment that may otherwise present a risk of
electric shock, injury to persons, and
b) Retards propagation of flame initiated by electrical disturbances ocurring within.
