This one ended up not fitting into our breaker box. And I had to return it. My fault, but you should be very careful when ordering that you get the right one

Installed electric to rv and outbuilding

I ordered this breaker after the first breaker I bought had the wrong mounting tabs. I installed a tesla charger that requires 240V. Breaker is built well and worked flawlessly with no issue. Highly recommended 👌 💯Update - Buyer Beware!!! This breaker is a fire hazard!!!!!! DO NOT BUY!!!!!! From this moment on, I will only write reviews after 6 months of use of the product. My Tesla charger quit working in the middle of the night. My app alerted me that it was disconnected. I missed it because I was sleeping. I quickly realized first thing in the morning, the charger was inoperative. So I went into the basement to check to see if the breaker tripped and found that not only did it not trip and it smelled like electrical burning. I quickly shutoff the breaker. Upon removal and inspection, the cheap hold down screws were wiggling back and forth causing some arcing apparently, but never tripped the breaker. I replaced it with the Eaton correct breaker. When it comes to electrical you should not mess around. Get the right stuff. Shame on this company for having such a pathetic part that could have burned my house down, and shame on me for not doing better research.
