This new Second edition was issued to clarify the UL effective date statement shown on the Preface page and to make other administrative changes.
The Second edition also includes the addition of a national difference for Clause 23.101 to require that the supply cord length be not greater than 0.5 m for constructions where the motor and the primary supply switch is located in a separate motor unit
As noted in the Commitment for Amendments statement located on the back side of the title page, UL and CSA are committed to updating this IEC-based binational standard jointly. However, this Second edition dated December 7, 2007 will not be issued by CSA since CSA C22.2 No. 745-2-12 is no longer being maintained.
