I just got these, and will be writing a full review soon, but yes they definitely work on the breaker panel.
My system is rather unusual in being run 4 ga off a 240v circuit, Audio Consulting step down transformer to 120v, then 4 ga direct into my Frankenstein power conditioner. Still, with all of that, one Omega Mat on the breaker panel dropped the noise floor, improved inner detail and- well wait for the review!
