1. An electrical panel comprising:
a main service breaker terminal configured to receive a main service breaker;
at least one busbar coupled to a plurality of branch circuits;
a plurality of controllable relays electrically coupled to respective branch circuits of the plurality of branch circuits;
a plurality of breaker terminals electrically coupled to respective controllable relays of the plurality of controllable relays, wherein each of the plurality of breaker terminals is configured to independently trip a respective breaker;
a plurality of current sensors, each comprising a respective transducer for generating respective sensor signals indicative of currents in respective branch circuits of the plurality of branch circuit;
a current measurement shunt attached between the main service breaker terminal and a busbar of the at least one busbar; and
control circuitry coupled to the main service breaker terminal and to the plurality of controllable relays, wherein the control circuitry is to control the plurality of controllable relays based on at least one of the respective sensor signals or on a current flowing through the current measurement shunt.
