Worked perfect in my electric circuit board. It was very difficult to find elsewhere, but this seller had it and it was sent fast. Now I finally have some electricity back in my home!

I purchased this to use with a generator interlock kit (for a homeline panel) and it works great. I’d recommend hiring a licensed electrician if you’re not familiar (and comfortable) with working inside a breaker box as it can be deadly. Installation was quite simple, and it fit exactly as it was supposed to. It’s had power running through it for quite a while now without any issues. I’d recommend it.

Not a typical DIY project. Must pull service meter before replacing this main circuit breaker, unless there's a disconnect between the meter and the breaker box, which is hardly ever the case. Had meter pulled by electric provider and changed this out easily. No fit issues, no problems.

I purchased this to replace a weak breaker in my house. I couldn't find this anywhere locally so Amazon here I come. Installing was easy. Once the meter was off I removed the old breaker and installed the new one. New bolts came in the box. Perfect fit!
