Foreword

This is an update to "Hazards of Working Electrical Equipment Hot," a NEMA white paper originally published in 1994. To ensure that a meaningful publication was being developed, draft copies were sent to a number of groups within NEMA having an interest in this topic. Their resulting comments and suggestions provided vital input prior to final NEMA approval and resulted in a number of substantive changes in this publication. This publication will be reviewed periodically by the Molded Case Circuit Breaker Product Group of the Low Voltage Distribution Equipment Section of NEMA for any revisions necessary to keep it up to date with evolving technology. Proposed or recommended revisions should be submitted to:

Vice President, Technical Services
