Expert Analysis

A new list item has been added to clarify aquariums, bait wells, and similar open aquatic vessels or containers, such as tanks or bowls, where receptacles are installed within 6 ft (1.8 m) from the top inside edge or rim or from the conductive support framing of the vessel or container, in other than dwelling units, are required to have GFCI protection for personnel. A significant shock and electrocution hazard exists in other than dwelling occupancies where aquariums or live bait wells are located near receptacle outlets. This hazard is very similar to receptacles within 6 ft (1.8 m) of a sink, bathtubs or shower stalls which are all required to be GFCI protected.
