If wet rated conductors are installed, does not that mean the conductors should work properly after a hurricane (with water penetration) since they are "wet rated"?
The listing of the conductor insulation is based on the normal conditions of use. A conductor with a wet rating, like THWN-2 is permitted to be installed in a conduit that is installed in a wet location. As an example, in the conduit installed between light poles in a parking lot.
Now as for the performance after a natural disaster like a hurricane, a conductor with a wet rating may be able to withstand the storm without issue as long as it remains undamaged. However if the conductor is subjected to any adverse conditions, like contaminated flood water, then all bets are off because the conductor insulation could of been damaged and can cause a failure.
The best advice is to contact the conductor manufacturer if possible. NEMA also has a whitepaper on the reconditioning of electrical equipment, which can happen after a natural disaster.
"If wet rated conductors are installed, does not that mean the conductors should work properly after a hurricane (with water penetration) since they are "wet rated"?"
I would say, "no." It doesn't necessarily mean that they should work after a hurricane. There could be wicking and other things that could affect the insulation integrity.
It sounds like this could be a "spin-off" of the previous question...about the appliance (that is not cooking equipment).
There is no way to rationalize having "non-wet" rated conductors in PVC...IMHO.!!
