For quite some time, I have been installing GFI outlets at every exterior location feeling that it was an added layer of safety. Now I question whether this was the best thought I've ever had or not. However, I always use Hubbell or P&S devices, commercial grade is the low-end, nothing less, Spec grade where the job allows.
After viewing the picture and reading some of the posts, I tend to agree with the comments of Dan in that the GFI devices should be installed indoors and feed downstream exterior outlets. Not a bad thought, but I'm old school, and still like the extra feel-good of having protection at the device. I also would question if the device picture were in a weather proof box, how did excessive amounts of moisture get to the device? A leaky gasket perhaps? WAB
