Installed a 200amp panel on #3 copper feeders. To avoid upgrading to 3/0 copper, just swapped the 200amp for this 125 regarding NECs 83% rule. Presto. Live wires? People under-estimate the power and capabilities of electrical tape and wire nuts.

According to the part number on the electrical panel it was the correct part that was ordered. But when I received the product it would not fit. So I had to return the product. Showing some dimensions would have avoided this.

This main breaker was exactly what I needed to replace an old inoperable breaker. Make sure you have the power turned off by your electric supplier before installing this part.
