i agree with the others that say the homeowner is not telling the whole story. he probably made a stupid mistake and fixed it before you came to save himself embarrassment. feel there is something wrong with the breaker and you wish to contact Sqaure D but you want to tell them EXACTLY what went on when the breaker failed.

say this to the homeowner "this breaker may be defecteve and Square D needs to know exactly what occurred when the breaker failed. If it is defective, thousands of people's lives may be at stake and Square D needs to be able to recall the product."

make sure you don't put the owner at fault i.e. "I know you did something wrong and covered it up" that won't get them to talk. [Linked Image]
