Hello Everyone… This is my first post to the board, and I have to say I enjoy reading and learning from all the experiences( bad & good) that all of you have shared! I know there is no stupid quesiton especially when it comes to electrical, so here it goes. I was inspecting a 41yr old split level house with a newer 200amp service. I had not inspected the panel just yet, but as I was testing one of the 10 outlets in the garage(8 grounded, 1 GFI, 1 Open ground) the outlet next to the GFI sparked like the 4th of july melted the two prong on my tester and tripped the breaker. This was the first time this had ever happened with over 450 inspectons under my belt. What could have caused this to happen? I should have mentioned this was a general contractors home…!
Any help would be greatly appreciated.
