Distributors with computers are already aware of the need for surge protectors to protect their equipment from potential damage caused by sudden increases in electricity coming from the wall outlet.  These are often called “spikes”, because the voltage jumps very quickly.  In parts of the country with heavy lightning activity, people are certainly aware of the need for protection, and many people use surge protectors for all their household appliances.  Even in some city electrical systems, a power drill or even a hair dryer switched on anywhere in the building can cause a fluctuation in the current level.

To be on the safe side, we recommend that you add a surge protector to your change machines.  Your Refreshment Center doesn’t really need one, since the refrigeration compressor isn’t “on” all the time.  A surge protector is especially recommended if both your change machine and your Refreshment Center share the same power outlet; you never know what kind of electric “hash” is going to come down the line from the wall plug. 

If you don’t already have a surge protector, they can be found at almost any computer store or Radio Shack.  Prices start around $5–15 for a single outlet, and you can get multiple outlet strips for about $12–25.  Some surge protectors even help protect against lightning strikes, if you live in an area where lightning is a common occurrence.  And here’s a tip for computer users that don’t have a surge protector yet: you can get models that also have plugs for your phone line (see the model in the top picture), to protect your computer modem or fax machine—an important safety measure in lightning country or during storm season.
