Abstract
An apparatus for and method of evenly distributing an electrical load across an n-phase power distribution network. The current in each incoming phase and in each branch circuit is measured by a current sensor. The outputs of the current sensors are monitored by a processor. Associated with each branch circuit is a multi-pole switch and a conventional circuit breaker. Each switch is able of connecting its corresponding branch circuit to any incoming phase, and of disconnecting the branch circuit from all n phases. The processor periodically monitors currents flowing through each incoming phase and, based on branch circuit load conditions, reprograms the switches to keep the branch circuit loads evenly distributed across all three incoming phases. A further feature provides the pre-programmed, processor-controlled, changing of load connections, for example as a function of time-of-day; and to provide a 'priority list' for dropping loads in case of an overloaded power-line condition, and for subsequently reconnecting loads. A further feature provides telephone communication between the processor and the electric company, including the capability of transmitting information to the electric company. The capability of the electric company to make inquiries of the processor, e.g., concerning loading of each of the phases. The capability of the electric company to issue commands to the processor, e.g., to connect or to disconnect loads, and the capability of the electric company to remotely alter the programming the processor via the telephone connection and the ability to monitor electric power consumption.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
