We did a remodel job for a GC two years ago. His homeowner calls regarding an Arc Fault breaker that has tripped and won't reset. My initial thought is that the breaker has gone bad and needs replaced.

Here's my hang up. We installed the circuit and the breaker on the remodel. My brother is there at this very moment to try and determine the problem but my money is on a bad breaker.

At any rate, should I expect to be compensated for this? Should I expect Square D to replace a two year old breaker? Or do I eat it and call it outstanding customer service? What to stop them from calling me in ten years expecting me to replace something else that "went bad"?

How would you treat this situation?

THANKS!
