Divers using electrical equipment are exposed to shock hazards. The Naval Civil Engineering Laboratory NCEL tested commercially available ground fault protection devices designed for terrestrial use and found that none of them met Navy BUMED criteria for protection against electrical shock. The objective of this development was to meet the BUMED criteria using the most desirable features of current technology. NCEL developed a prototype system that detects low-level current less than 5 mA and terminates the current flow within 10 msec, a requirement inferred from the BUMED criteria.
