The snow blower and extension cord got in a fight...there was no winner. Yes, the cord was plugged into an exterior outlet and the insulation shredded off the wires. My bathroom and exterior GFI outlets are on the same 20A GFI circuit breaker. The breaker triped, however I am unable to reset it. Could the breaker have actually 'broke'? I purchased a new one, which to my surprise was quite expensive compared to a non-gfi breaker. I just want to make sure this was in fact the problem before going through the hassle of replacing it.

Appreciate any feedback.
