Unbalanced 3-Phase Supply Voltage   Never operate a motor where a phase imbalance in supply   voltage is greater than 2%. Use the formula in the example   (see column to the right) to determine the percentage of volt-   age imbalance.   Determine maximum deviation from average voltage.   (AB) 397 – 393 = 4 v   (BC) 403 – 397 = 6 v   (AC) 397 – 396 = 1 v   4. Installation with Accessory Electric Heaters   Size the Field Power Wiring between the heater TB1 and the   40RU indoor fan motor per NEC Article 430---28 (1) or (2)   (depends on length of conduit between heater enclosure and   40RU power entry location). Install wires in field---installed   conduit.   Maximum deviation is 4 v.   Determine percent of voltage imbalance.   6 % Voltage Imbalance   = 100 x   = 1.5%   397   This amount of phase imbalance is satisfactory as it is below the   maximum allowable 2%.   IMPORTANT: If the supply voltage phase imbalance is more than   2%, contact your local electric utility company immediately.   Catalog No: SS524J---01   2011 Bryant Heating and Cooling Systems.
