Ken with the Pergo flooring there should be a 1/4" space between the wall and the flooring that is covered up with some type of moulding (shoe or quarter round usually). The gap is allowing for expansion of the flooring, you may want to research whether or not it is advisable to run wire within that gap ... I would probably think not. With carpet you'll not have that issue with the wires.
