Abstract
Abstract A time delay power controller has a power input for receiving alternating electrical power from an external source; a timer activation device connected in parallel to a one or more timers, each timer having an associated delay time and an output for delivering power after the delay time has elapsed and a plurality of contactors, with a first contactor coupled to the timer activation device and the remaining contactors coupled to the output of a respective timer. Each contactor is coupled to one or more associated circuits. The first contactor allows delivery of alternating electrical power to its associated circuits when the timer activation device is enabled and the remaining contactors allow delivery of alternating electrical power to their associated circuits when the respective timer's delay time has elapsed. The controller may be enclosed in a housing. The controller may be configured to sequentially power lighting circuits.
