I've been reading articals on camp chef pellet smoker where people says when it's raining water gets inside the smoker why would anybody use this smoker that is plugged into a electrical outlet that runs a pellet box that has a circuit board in it while it's raining can someone help me out here thanks
First, give us some links to these "articals" [SIC] to show us you're not a troll.
Second, I'll pretend you're not a troll and give you some comments.
The Tragers, CCs, and many others have lids with hinges near the top and lap joints between the lid and the cooker body. Any of these may leak water. The amount and frequency depends on the rain volume, wind direction, etc. It's a relatively harmless thing, though damp ashes are corrosive and probably should not be left in the cooker. A good cook will dry the rain, though, then you're back to the same dry ashes you started with.
I have both a Traeger and a CC DLX. The covers for the pellet hoppers are slightly different. The Traeger cover is flanged and overhangs the pellet hopper body. The CC is flanged but the flange fits into a groove in the hopper top with the groove drained to the outside through many punched holes. I suppose in theory there could be strong enough rain to overcome the drainage from the holes. A hurricane perhaps? It is not something I worry about.
Regarding electricity, water entering a pellet hopper is very unlikely to get near any electricity in the area below the hopper. Ditto water entering the cooking chamber. I wouldn't worry about it. Actually your main concern, though a small one, should be getting the wall outlet and the plug wet plus any plugs and sockets on extension cords you may be using. Those all get the rain directly, not via some hypothetical issue with the cooker construction.
And ... even then there is not much of an issue. For 90%+ of us, our outside and garage outlets are wired per the National Electrical Code, which requires GFI protection. So if your wall plug really gets sluiced and the water is not pure (pure water is not a conductor), the GFI will pop.
Finally, they sell cooker covers for a reason. Most of us want to protect our expensive purchase. With a cover there is no water concern at all.
So ... "who would buy?" Anyone looking for a good cooker at a cost-effective price. There are several features on the CCs that are superior to the Traegers and others in that market segment. I had the Traeger first and it was a no-brainer to switch to the CC.
Don't forget to give us those links.
