Why did you pick this product vs others?: Well, thus far, my load has not experienced a fault so I cannot report if it actually works. I am hopeful however and pray that it will function when called upon every day. Construction seems good, operating handles work without hesitation. Termination hardware gave me no grief and seemed of typical/average quality.
