Comment responses and substantive change for the proposed Eleventh Edition of the Standard for Switchboards, UL 891. This is a proposed tri-national harmonized standard.

UL Standard for Safety Switchboards

ANSI/IEEE C37.59:2007 电源开关装置的转换用标准要求

This standard covers power switchgear equipment that is converted from a qualified design. It provides direction and guidance in those conversions and specifies required design verification in accordance with applicable American National Standards Institute (ANSI), National Electrical Manufacturers Association (NEMA), Underwriters Laboratories Inc. (UL), or IEEE standards. This standard also recognizes that production/field testing does not provide design verification. This can only be accomplished by means of design testing and technical evaluation.

Standard Requirements for Conversion of Power Switchgear Equipment

ANSI/NECA 430-2006 常压开关设备安装标准

This standard describes site preparation and installation of medium-voltage switchgear rated 2, 400 Volts to 34, 500 Volts.

ANSI/IEEE C37.21:2005 控制配电盘标准

Covers ratings, construction, and testing of dead-front control switchboards containing but not limited to devices such as switches, control devices, instrumentation, metering, monitoring, protective and auxiliary relays, and regulating devices and accessories. It includes, but is not specifally limited to, switchboards for the control and protection of apparatus used for or associated with power generation, conversion, transmission, and distribution.

Standard for Control Switchboards

UL 891-2005 配电盘

1.1.1 This Standard applies to switchboards nominally rated at 600 V or less and intended for use in accordance with the Canadian Electrical Code, Part 1 (CE Code, Part 1), the National Electrical Code (NEC), ANSI/NFPA 70, and the Mexican Standard for Electrical Installations (Utility), NOM-001-SEDE. 1.1.2 In this standard the term switchboard is intended to refer to a dead-front switchboard. 1.1.3 These requirements do not cover the following switchboard types: preset and dimmer control (theater), live front, railway control or electrification; or constructions intended only for receiving motor control center units. 1.1.4 These requirements cover switchboards for use on circuits having available rms symmetrical short-circuit currents of not more than 200000 A.

UL 991-2004 固体器件安全控制装置的试验

1.1 These requirements apply to controls that employ solid-state devices and are intended for specified safety-related protective functions. 1.2 These requirements address the potential risks unique to the electronic nature of a control. Equipment or components employing an electronic feature shall also comply with the basic construction and performance requirements contained in the applicable end-product or component standard. These requirements are intended to supplement applicable end-product or component standards and are not intended to serve as the sole basis for investigating the risks of fire, electric shock, or injury to persons associated with a control. 1.3 These requirements do not cover controls covered by end-product standards in which an electronic control investigation is specified. 1.4 Sections 9 - 22 contain standardized test methods for investigating the performance of an electronic control when subjected to particular environmental stresses. The suitability of each test to a given control shall be determined by the end-product standard(s). Determination shall include an assessment of: a) Whether the control will be exposed to a particular environmental stress in its application, and b) Whether the response of the control to a particular environmental stress is relevant to its intended safety-related protective function in its application.

UL 244A-2003 设备的固态控制装置

1.1 These requirements cover component electronic controls intended to be factory installed on or in appliances and other utilization equipment rated 600 V or less, used in ordinary dry locations as defined in the National Electrical Code, NFPA 70, and that comply with the requirements for such appliances and equipment. 1.2 For a control covered by this standard, it is assumed that: a) No voltage greater than 600 V above ground will be present in a control, b) An isolation transformer, if provided, will generally furnish power at a lower potential than the primary voltage, and c) The output of the control will not be located in a circuit operating at greater than 600 V above ground in the end-use product. If conditions other than these are provided, consideration shall be given to the need for additional requirements.
