The project
You join Calderfield Panel Systems Ltd (simulated company)
You are the junior design engineer on one machine control panel. In four weeks you size the cables, check the GA drawing and the parts list, work out the heat in the enclosure, and meet a motor that does not match the drawing. The client then swaps the drive after procurement and you control the change: heat, space, wiring, protection and documents. A contactor has a 20 week lead time, the factory test finds an insulation failure on the day before shipping, and sales wants to ship anyway. You review the routine test certificate, walk the panel against the machine wiring standard and hand over a design pack. The skill is to keep every number and revision honest.
The people in the story are roles, such as Lead Engineer, not real people.
