On February 14, 2007, the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) issued a final rule for its updated electrical installation standard.  This is the first significant change in approximately 25 years. The updated standard includes a new alternative method for classifying and installing equipment in Class 1 hazardous locations, new requirements for ground-fault circuit interrupters and new provisions on wiring for carnivals and similar installations.
