I worked on a site which included a pumping station, 2 vfd buildings, along with 2 high voltage substations, 4166v switch gear and 2 huge storage tanks. The project was interesting, I dealt with mainly tying in the high voltage to and from switch gear to substations, vfd bldgs, and pumps. Along with this I hooked up controls for vfd's, lighting circuits, pumps and remaining systems.
I worked for a subcontractor to Enbridge, we finished our contract in full prior to deadline, and without injury.
Was a fun show.
