CSA M421 is the Canadian mining electrical installation standard and Jarret Solberg (NETA Level 4, Magna Electric Corporation, Regina) has been the representative throughout the latest revision cycle. The public review period is over, and the document will be released later this year. Many discussions centered around the requirements for maintenance and acceptance testing, and references to the NETA standards were included in the latest revision.
CSA Z462 is in a revision cycle and will be scheduled for release early in 2012. This document is closely aligned with NFPA 70E and much activity was created in the revision process of both documents.
