Abstract
A branch circuit includes an branch breaker, a master outlet, and two slave outlets in series with the master outlet. The master outlet is the closest of the outlets to the circuit breaker. It includes a power sensor, the output of which is graphically displayed on a multi-segment LED display visible from the front of the outlet. The power sensor output is also supplied to displays at the slave outlets so that the power measured at master outlet is indicated at all outlets. This allows the available power capacity for the branch circuit to be appropriately indicated at all outlets on the circuit. The design can be implemented inexpensively enough that it is economical to employ the invention at every outlet in a building.
