A switchboard is disclosed having a mains power input circuit (A, N) and a plurality of output circuits (HOT WATER, OFF PEAK, OVEN, LIGHT, POWER2, POWER1) and including a central processing unit (CPU) for controlling a plurality of controllable circuit breakers (BREAKER1 to BREAKER6). The breakers are controllable by the CPU. Sensing means (J14, T2, T4) provide the CPU with instantaneous voltage and current magnitudes to enable the CPU to determine power consumed by the output circuits. |
