Both sets of wires have insulation on them that are rated for better than 600 volts. That's 1200 volts of insulating capacity between them according to the specs. The 400 hz is immaterial.
The only thing I can tell you is that you're wrong.
No, you cannot "tell" me that, you can assert it, but to "tell" me something, you have to know something about the subject, and I can clearly see that you don't.
The NTSB found that not only are low and high voltage wires routed together by design, but sometimes they are routed together against design.
And you never did answer my question about what the NTSB would do if the President ordered them to Deem it an accident.
What would they do?

You don’t have to believe me. Look at the NTSB report on the condition of the wires recovered from TWA800 and wires observed on other aircraft of similar age. They also have information on the routing of the wires and as I mentioned before the results of laboratory testing that demonstrated arcing and the energy of the arcs.
