My concern and question has to do with the electrical wiring part of this, which I realize is shakey. I'd like to know how shakey, and what alternatives I have.
The 2 fans have been in use at my relative's house, wired as described above, for a few years. I realize that hard-wiring with heavier gauge would be the best option but I would like to hook them up as they were (i.e., 16 gauge with plug in). To probably make it worse, I would like to plug it into an outdoor extension cord that I have in the awning framing for a string of rope lights. My relative thinks there's no problem with this (It worked OK in his house for years) but I'm fearing that I'm exceeding amp limits. I have a 15 amp service. I live in the Northeast so I would only have the fans up for about 4 or 5 months in the summer.
Can anyone tell me if this is a safety hazard, and what could happen, or if this would be OK? I'd appreciate all informed opinions and recommendations.
