Release # 88-095 WASHINGTON, DC- In cooperation with the U.S. Consumer Product Safety Commission (CPSC), Challenger Electrical Equipment Corp. of Malvern, Pennsylvania, voluntarily offered free replacement of its 15 and 20 ampere type HAGF single pole ground-fault circuit-interrupter (GFCI) circuit breakers.These type HAGF-15 and type HAGF-20 circuit breakers were manufactured between February 22, 1988 and April 29, 1988, and most were sold nationwide to electrical product distributors during this period. Some may have been sold to consumers by retail hardware or lumber outlets. Approximately 9000 of these devices have not been located, some of which are believed to have been installed in residences.

The code also requires GFCI protection for receptacles in hotel and motel bathrooms. The HAGF circuit breakers, which may require replacement, are located in the electrical service panel. If the name "Challenger" is embossed on the front of the panel (on the door handle) and/or on the label on the back of the panel/door, that panel may contain circuit breakers requiring replacement. Affected circuit breakers have a yellow button and the word "test" in raised letters on one side; on the other si
