A couple of the drawings show what appears to be a residential service panel, but with a device at the bottom that looks like a multi-position rotary switch. These were typically used in motor starters and speed controls to select taps on a resistor or autotransformer, so I'm wondering why one would be installed in a residence. Perhaps for manual voltage regulation?
I don't have the slightes idea what this could have been... the entire panel looks weird so my best guess is that the artist didn't really know all that much about electricity and those details have to be considered "artistic liberty". On the other hand, many details are surprisingly accurate, but that's mostly restricted to the "everyday life" details.
