What would be an allowable time elapse for current-limiting devices to respond to if a ceiling fan light kit consumes more than 190 watts?
The Department has received inquiries seeking clarification on whether any time may elapse before a current-limiting device prevents all lamps in a ceiling fan light kit from consuming more than 190 watts in total. The Energy Policy Act of 2005 established a requirement that all lamps on ceiling fan light kits other than those with medium screw based sockets and pin-based sockets for fluorescent lamps manufactured on or after January 1, 2009, shall not be capable of operating with lamps that in total consume more than 190 watts. (42 U.S.C. 6295(c)) These statutory requirements further the Act’s purpose of achieving energy savings during the course of normal operation of ceiling fan light kits. Manufacturers may choose to follow one of several possible design pathways to comply with this energy conservation design standard, including, but not limited to, a fuse, circuit breaker or other current-limiting device. 72 FR 1270. Current-limiting devices may vary in how quickly they respond, w
