Yes, but it always creates problems. Romtec Utilities has performed system start-ups on generator power but prefers that the system start-up take place on utility power in order to troubleshoot any problems by mirroring normal running conditions. If the utility power is incorrectly phased, the control panel and the overall lift station will not function. As part of the lift station start-up, Romtec Utilities ensures that the power has been connected in the proper manner to ensure that the pumps function as designed. Although Romtec Utilities provides built-in phase rotation protection, mixing up the power phases during install could run the pumps in the wrong directions or in a manner that is harmful to the mechanical systems.
