The electrical code states that receptacles located within 1.5 m of a sink (wash basins complete with drainpipe) shall be protected by a ground fault circuit interrupter (GFCI) of the Class A type. This rule was introduced in the 2002 edition of the electrical code and does not retroactively apply to older installations; however installations of new wiring in older kitchens are subject to this requirement.
Receptacles intended for a stationary appliance (designated for the location) and located behind the stationary appliance such that it is inaccessible for use with general purpose portable appliances are exempted to the above requirements.
