The shielded surge suppressors we sell start out as Belkin surge suppressors. We then heavily modify them by hand in our shop in Rockford, Illinois. We have been shipping the surge suppressors with "Light Almond" color cords for quite some time now. You can tell it is our EHS-Shield cord, because imprinted on the cord is the word "SHIELDED" It is also 8 foot in length. The standard Belkin cord is 15 feet, black, unshielded of course, and does not contain the word shielded on the cord.
So these are ways you can tell. There are a few other ways as well. Another great way is by testing the cord with a no-contact voltage sensor, or an actual electric field detector or meter. These devices will all show you that the cord is very well shielded and is not putting out detectable electric fields.
Thank you for your question. Is there anything else we can answer?
