We used 25 KV at work, and used H2O as coolant at 25KV to earth. The
leakage wasn't enough to trip an RCD. The path length was a little
larger than that in 2.5mm T&E.


yes..distilled water..once you get any dissolved salts the conduction is
WAY up.

Indeed. I mounted a relay in the car in a stupid place where water could
drip onto it. It gave problems within weeks. The contacts went high
impedance although it still clicked.
