we buy basic panels and then cut/drill/fabricate to fit our needs for that work cell I just got done cutting holes in 3 different panel doors for 20" HMI screensI work for a small automation company that designs control panels for machinery or entire production lines. This is 99% 480vac or 575vac and 1200 amp main breakers or smaller. I supervise the drawings & panel builds while writing the programs that I load in the PLC's, HMI screens, and variable frequency drives. I might work in the office for a month or more before travelling to the end user to commission the machinery. It's the perfect amount of travel now. Earlier in my career it was the inverse.
I have worked all over the United States. I have traveled to Canada (once), Brazil (10+), Mexico (twice), Guatemala (twice), Honduras (once). Brazil is my favorite. All international travel is halted due to Covid. Travel within the US is first class flights only, or driving. Right now I'm in California on a startup for a 750hp filtration system (three 250hp fans) for a recycling facility.
