Recent testing by Northbrook, Ill.-based Underwriters Laboratories (UL) of samples obtained from both the marketplace and several manufacturers indicates that some GFCI units do not meet all current UL requirements and, under rare conditions, may not trip when a fault is present, resulting in a loss of protection from electric shock. There have been no reported incidences of these products causing injury in the field, and under normal circumstances UL expects these products will perform their intended function. While GFCIs provide an effective means for protecting against electric shock, UL recommends that they be tested regularly to verify they are operating properly, using the self-test feature that is built into these devices.

UL has notified all manufacturers identified to date whose product samples did not meet all current UL requirements so that they may take appropriate action. UL has not withdrawn its certification mark from existing products nor does UL believe the products should be removed from homes or other locations entailing normal use.

Name of Product: Wall receptacle-type GFCI, rated 15A or 20A, 125V
Advisory: Under rare conditions, these GFCIs may not trip when a fault is present and may malfunction resulting in a loss of protection from electric shock. There have been no reported incidences of the products causing injury in the field.
Identification: GFCIs look like duplex receptacles but are distinguished by their "Reset" and "Test" buttons.
Uninstalled Product: All manufacturers identified to date have been notified. Retailers, contractors, and electricians should contact the manufacturer for further information.
