I heard some electricians say that in some towns its required to have a GFCI outlet regardless if that circuit is protected by GFCI breaker. Furthermore, I even heard that if you are installing a 2 outlets, both must be wired in parallel and both must be GFCI outlet. Can this be right? I was planning on not installing a GFCI outlet as my breaker is CAFCI/GFCI protecting the entire circuit. An additional question is, does an outside receptacle have to be "WR"? Is there a big advantage for having it WR?

I'm running a dedicated 20Amp outlet(120V) to the other end of my home, 75-80Ft from the breaker box. The only thing on this circuit will be a 1800W Flash Dryer. I am a bit unsure if I should go with 12/2 or 10/2 since the run is about 75-80 feet from the breaker box. I will be using UF-B wire since its going under the home to the destination. I would like minimal voltage drop. My plan was to run it from a 20A breaker under the home directly to the outlet. I'm not sure if 10GA would fit on a 20Amp outlet- or if its overkill- On another thread I read that 10 Ga would be needed- and some people said 12Ga would be fine ( But their scenario was different than mine with the load). The flash dryer is rated for 1800W and stays on constantly ( 15 minutes or so) until its heated- then its load drops to just maintaining temperature. Thank you in advance for any advice.
