UL 1030 BULLETIN

Abstract

Scope: These requirements cover industrial-use medium voltage metal-sheathed heating elements intended for use in appliances and equipment that comply with the requirements for such appliances and equipment. The requirements in this Supplement are applied in addition to the requirements specified in this standard. These requirements cover sheathed heating elements rated between 601 and 15,000 V. These requirements cover between the cold pin of the element and the end cap. These requirements do not cover heating elements for use in equipment for use in hazardous locations as defined in the National Electrical Code, NFPA 70. Wherever the terms heating element and element are used in these requirements, they are intended to mean a sheathed heating element as defined in Section 2.4 of this Standard. The medium in which these elements will be used is to be determined by the end product. These requirements cover cartridge-type sheathed heating elements that do not incorporate a bend in the sheath.
