The Progressive EMS-HW50C is only about 10" long, 4" tall, and 6" wide, so it'll fit almost anywhere that a small shoe box will go.... If your power center is below your fridge (many are), the fridge is much deeper than the power center, so it will likely easily fit in the space.
I installed mine on Friday. Relatively easy, just pick-up a 3' length of 6-3w/ground (about $6 at Home Depot)as that will make your installation easier, if you put that between the power center and the EMS unit.
