Review on Square Schneider Electric QO115PCAFI Single Pole by Shane Minter

These items may not work with your existing wiring unless your house is perfectly wired. Ie: no shared neutrals, bad territory, 12-3 shared neutrals, e.g. you would immediately stumble over me. I couldn't use them on the circuits that needed them most (old fabric wiring). Also, you cannot return electrical parts for a refund unless they are defective. I spend $250 for 6 of these and it doesn't work for me.
