Wes,

When it comes to electrical cords, I always try to get the beefier ones. For the TS, I would get some #10 cord at Home Depot or Lowes. Find the soft kind (sorry, I don't know the brand/style/type) that flexes nicely (you'll know it when you pick it up) and you'll be good to go. It will be a bit spendy but will work for you. I can't imagne using Romex for an extension cord!!
