The Occupational Safety and Health Administration (OSHA) recently learned of a hazardous condition that may exist in certain molded-case circuit breakers modified by a third-party rebuilder. The breakers may have an actual rating of 600 volts AC (alternating current) (VAC) or less, but are labeled as 1,000 VAC and may contain incorrect parts that can cause the breaker to malfunction.
