I have a Lee 110 volt 20lb pot. The area I have set up in my garage for casting doesn't have any power on that wall. I would have to run an extension cord maybe 15ft across the garage to my table. Would a 16 guage outdoor extension cord be sufficient without getting hot and posing a fire hazard as well as provide necessary power to the pot? I have one outlet that is closer but it's on the ceiling where the garage door motor for that side if plugged in. A cord from there would only need to be 6ft long. I would also run a fan over there as well to blow heat and any smoke/fumes out the door, but it would be on a separate cord from another outlet.
