Underwriters Laboratories Finds Faulty GFCIs
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 UL has not withdrawn its certification mark from existing products nor does UL believe the products should be removed from homes or other locations entailing normal useArticle: | Underwriters Laboratories Finds Faulty GFCIs | |
