## Customer Reviews

### ⭐ 300AMP failed where 100AMP worked fine.
*by I***D on April 15, 2018*

I installed this in my RV with solar and while out camping everytime I started my microwave it would pop. I moved some things around and used a 100amp and it didn't pop. This is a 300amp that popped every time and the 100AMP did not. It could be a bad breaker.

### ⭐⭐⭐⭐⭐ As advertised
*by E***Z on June 30, 2019*

Just as expected...no letdowns or disappointments.
