UL Standard for Safety Automatic Electrical Controls for Household and Similar Use; Part 2: Particular Requirements for Energy Regulators (First Edition)
"This clause of Part 1 is replaced as follows: In general@ this part of International Standard IEC 60730 applies to ENERGY REGULATORS for use in@ on@ or in association with equipment for household and similar use@ including ENERGY REGULATORS for heating@ air conditioning and similar applications. The equipment may use electricity@ gas@ oil@ solid fuel@ solar thermal energy@ etc. or a combination thereof. This standard applies to ENERGY REGULATORS using NTC or PTC THERMISTORS@additional requirements for which are contained in Annex J. These ENERGY REGULATORS may be thermally@ mechanically or electrically operated This Part 2 applies to the inherent safety@ to the OPERATING VALUESOP@ ERATING TIMES and OPERATING SEQUENCE where such are associated with equipment safety@ and to the testing of automatic electrical ENERGY REGULATOR devices used in@ or in association with@ household or similar equipment. Throughout this Part 2@ the word ""equipment"" means ""appliance and equipment. "" This Part 2 does not apply to automatic electrical ENERGY REGULATORS designed exclusively for industrial applications. This Part 2 is also applicable to individual ENERGY REGULATORS utilized as part of a control system or ENERGY REGULATORS which are mechanically integral with multi-functional controls having non-electrical outputs. ENERGY REGULATORS for equipment not intended for normal household use@ but which nevertheless may be used by the public@ such as equipment intended to be used by laymen in shops@ in light industry and on farms@ are within the scope of this standard. This Part 2 applies to manual ENERGY REGULATORS when such are electrically and/or mechanically integral with AUTOMATIC CONTROLS. Requirements for manual switches not forming part of an automatic ENERGY REGULATOR are contained in IEC 61058-1. This Part 2 applies to ENERGY REGULATORS with a RATED VOLTAGE not exceeding 660 V and with a RATED CURRENT not exceeding 63 A. This Part 2 applies also to ENERGY REGULATORS incorporating ELECTRONIC DEVICES@ requirements for which are contained in Annex H."
