Bill and Gary, One way not to have a water resistant cable is to limit the voltage levels to Class 2 (power limited) "wet" levels. By doing this, an installer will not have to use specialized expensive wiring and special environment rated conduit fittings.

It therefore must have a 'W' in the name THW, THWN etc. Most 'THHN' is dual rated as THWN too. See ('99 NEC) Art 310-8(c) Look in Table 310-13 to see the Applications for the different wiring types.
