REPAIR WELL 3 AND WELL 5 WITH SCADA AUTOMATION SITE VISIT

QUESTIONS AND ANSWERS

QUESTION 1. Well 4 utilizes 480VAC VFDs, served by step-up transformers from the building 208 service. What is the service voltage at Wells 3 and 5? If not 480V, should the VFDs match the service size or will the step up transformer need to be provided by the contractor?
