An energy management load panel arrangement includes a load panel enclosure (10) having a plurality of circuit breakers (20), each of which opens and closes in response to a control signal so as to interrupt an associated current path. A microcomputer (120) generates the control signals to control the position of the circuit breakers (20) and their associated current paths and a, volatile memory circuit, for example RAM (126), stores time-event data which is used to indicate when the control signals should be generated.

Why it's free to use
- Filed June 17, 1993 and granted February 29, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 17, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
