Does anyone know of a case where a 250 kva transformer has "cooling"
water in the underground conduit carrying its cables? Stated another
way, does the NEC allow water to be used to cool cables in an
application like a strip mall? This transformer feeds a building with
small retail shops and the cables do NOT appear to be special purpose
cables. My guess is that water leaked into the conduit and the
electrician explained it as "water to keep the cable cool". I am NOT
an electrical engineer but I am simply seeking a little information
before taking my observation to the next level.
Thanks for opinions,
