<p>An apparatus for and method of evenly distributing an electrical load across an n-phase power distribution network. The current in each incoming phase (.SLZERO.1, .SLZERO.2, and .SLZERO.3) and in each branch circuit (1-5) is measured by a current sensor (16, 18, 20, 42, 44, 46, 48 an d 50). The outputs of the current sensors are monitored by a processor (12). Associated with each branch circuit is a multi-pole switch (22, 24, 26, 28 and 30) and a conventional circuit breaker (32, 34, 36, 38, 40). Each switch (22, 24, 26, 28 and 30) is able of connecting its corresponding branch circuit (1-5) to any incoming phase (.SLZERO.l, .SLZERO.2, and .SLZERO.3), and of disconnecting the branch circuit (1-5) fro m all n phases (.SLZERO.l, .SLZERO.2, and .SLZERO.3). The processor (12) periodically monitors currents flowing through each incoming phase and, based on branch circuit load conditions (1-5), reprograms the switches (22, 24 and 26) to keep the branch circuit loads (1-5) evenly distributed across all three incoming phases (.SLZERO.1, .SLZERO.2, and .SLZERO.3).</p> |
