Your TC probably does have a 30 amp plug but that doesn't mean you can't plug it into a 15 amp home circuit either. I have a 30 to 15 amp adapter that I use all the time (and I did buy it at WalMart). You just won't be able to run all the lights, microwave, air conditioner, etc. at the same time off the typical home circuit when it's plugged in that way. Normally when I'm at home and packing up to go, I have the TC plugged into a 15 amp circuit from the garage just to keep anything from draining the batteries while home. There are different plug configurations for a variety of different amps.
