Typically mounted on an interior wall inside a garage or under a carport, plugged into a standard outlet. For most Middle Tennessee homes — Franklin, Brentwood, Nolensville, Spring Hill, Thompson’s Station — that means the garage. For rural homes in Hickman, Perry, Wayne, or Humphreys counties where attached garages aren’t always standard, we sometimes mount in a utility room, mudroom, or basement near the breaker panel. The box is roughly 8″ × 6″ × 3″ and runs cool to the touch.
