Re: 2005 and In Use covers
My understanding is that wet locations already require while in use covers and damp locations do not. You have to look at the NEC definition of a wet location. Garage is not wet location, front porch is not a wet location. Uncovered side of the building (where the HVAC compressors are placed) is a wet location.
If your saying that there is a proposal to change this then thats news. 2005 edition is out so are you asking about a proposal for 2008?
Related question, aren't all the convenience outlets mounted in light poles (use in every city for holiday lights) now required to be while in use? Does anyone make such a pole?
