I recently have found that wire bridges are causing an overload bug when wired after a transformer. I discovered this after I decided to test something after loading an old save game before the launch patch, because i could have sworn that I had 2 transformers being able to pull from a generator line at the same time without having to limit my transformers to only one charging at a time depending on if the left one was needing to charge.
Using a wire bridge after a transformer causes issues.
However using a wire bridge before transformers causes no issues.
