The circuit check devices are inferior quality. I can't remember the last time I used one that did not create aggravation. As simple as they are if they fall apart or require repairs...It's aggravating. This opinion is coming from 3 different installers. This is the weakest link with the entire installation.
Thank you for the input John. I have asked our Engineering Supervisor - Scott - to contact you to understand the "break down". We appreciate your help in making us better! - Julia Billen, President
