Once you're used to looking at electrical enclosures they all sort of start to look the same. What you're describing in your photos are similar to what my company designs for all forms of industrial domains: agriculture, wastewater, oil & gas, mining, telecom, power, etc. https://www.hammfg.com/electrical https://www.hammfg.com/electrical Elsewhere in this thread someone talks about "optimization" and electrical enclosures are no different. There's various levels of certification that they need to meet in regards to the different environments they're installed to work in, it only makes sense that a standard style of design emerges instead of specifically engineering something per task. (EDIT: I should mention I do not work for hammond, I just linked their site because I know we use their enclosures a lot)
