Stamping plant saves money and goes from a 200a to 600a Service

This stamping plant had a total of (7) services entering the building due to years of additions. The project took one of the three 480V 3 Ph services from 200a to 600a, converted the service from a 480V (Delta) to 277/480V (Wye), and eliminated the old 800a 480V 1Ph (spot welder) service.

As a result of this project the plant:

1) Has the power and infrastructure it needs to move forward with its expansion goals

2) Has power in a configuration that meets its needs and eliminates large and expensive transformers down stream

3) Saves money by shifting single phase loads onto a more efficient 3 phase system, and eliminates an additional service charge from the utility

4) A simpler power distribution system within the plant

Emloh Electric took this project from idea to completion, coordinating engineering, First Energy, city permitting and inspections, and of course the construction.

As part of this project, we ran (2) parallel runs of 350 mcm copper to an 800a CT cabinet. From the CT cabinet we ran parallel 3/0 conductors to a 200a fused disconnect and a 400a Eaton Pow-R-line panel. We transferred the existing loads onto the new service, and demoed the obsolete service equipment. Finally, we updated the grounding, bonding, and labeling and passed the city inspections, first time. At that point the utility energized the service and the plant is now ready for phase II (Expansion).
