Summary of Topics.This Second Issue of Outline of Investigation for Transfer Switch Equipment,Meter Mounted,UL 1008M,is being issued to incorporate requirements for meter mounted transfer switches intended for use with permanently connected generators.UL Standard UL 1008UL 1008.1 Scope.1.1 This standard applies to the following types of transfer switches that have a maximum rating of 1000 volts for use in non-hazardous locations,in accordance with Annex a1,Item 1 a) Automatic transfer switches; b) Manual or non-automatic transfer switches;UL Standards for Manual Transfer Switches ASCO Power Manual transfer switches are sometimes used in backup power systems that serve loads classified as optional by the National Electrical Code &(NEC ®),and both UL 98 and UL 1008-listed devices are used in these systems.The following article compares important aspects of the respective testing standards.
·The capability to handle fault currents is verified by testing a transfer switch according to UL1008 Transfer Switch Equipment.This standard specifies testing criteria for confirming Withstand and Closing Ratings.Transfer switches become UL-Listed after a manufacturer submits documentation of successful testing at rated capacity accordingWhite Paper Non-Automatic and Manual TransferUnderwriter Laboratories,UL 1008 - Enclosed and Dead-Front Switches,8th Edition.Northbrook,IL.2014.Operating Non-Automatic and Manual Transfer Switches Non-automatic and manual transfer switches differ in operation from automatic transfer switches because the user must determine when conditions are acceptable for transferring loads.
