It supersedes and replaces the Technical Information Letter on Interim Certification Requirements for Pullout Switches, which was issued in 2016 as CSA T.I.L. D-35. It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
