Hello all, Very interesting questions. While at the C63 meeting one of the attendees asked how we measure the acoustic noise from speakers when testing radiated and conducted Immunity. We do not test PC's with speakers so no requirement. Telephone Terminal Equipment has a similar requirement.

Hi Stuart, Sounds like your referring to a PCMCIA radio card that can be integrated into a host device. If so, you probably have an RTTE project that does also include the LVD. The test suite for this device would depend on the frequency band. If its 2.4 GHz equipment, then EN 300 328(Radio

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. PETER S. MERGUERIAN Technical Director

Gary, Anything outside (which includes the interior of the conduit) must be rated for wet locations. 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

Does anybody have a clue what type of wire I can run in conduit for outside environments. Internally, I have to worry about riser cables and cables in air plenums etc, but how about if I am running through conduit from the base of a power pole to ITE equipment located at the top of the
