Received on the 3rd business day so pleased about that. I was concerned that the breaker may not be new though. The product page shows the breaker in the manufacture plastic packaging. The breaker I received was just wrapped in brown paper and has marks/scratches like it was used. So not sure what to make of that. As long as it works, that's fine as I saved about 40% from what I would have paid at the local big box store. I'll update this review once I have it installed.

I used this large breaker to handle the new 100 amp electric service to my storage building and small shop. It did a very good job servicing a new Square D 100 amp breaker panel from my existing home's 200 amp breaker panel. It took up only 2 slots in the 200 panel and fed the 100 amp panel in the next building. I ended up with 2 100 amp breakers servicing the out building; one in the 200 amp panel and one as the main 100 breaker in the new 100 amp panel. This breaker went into the 200 amp panel. The 100 amp new panel comes new with a 100 amp top breaker in the box; already installed.

I used this to supply my electrical sub-panel for my pool house. You can’t beat Square D products. It has worked flawlessly and I would definitely recommend.
