<p>In an electrical distribution system for controlling current paths through a plurality of associated circuit breakers (20), a programmable circuit arrangement operates the circuit breakers by remote control in at least the open and closed circuit positions. The circuit arrangement includes an array of termination points (38) which are used in sets, such that each set includes a plurality of termination points, wherein each set receives a remotely generated control signal for commanding the circuit breakers to open or close. A control circuit includes a microcomputer (32), which is coupled to the array of termination points and responsive to the remotely generated control signal, for controlling the circuit breakers between the open and closed circuit positions. The microcomputer reads the termination points, via an X-Y grid, by polling the X axis and reading the Y axis.</p> |
