Chief Investigative Correspondent Lisa Guerrero and the Inside Edition I-Squad put electricians to the test in the third installment in a special series of investigations. Inside Edition rented a house in Montclair, New Jersey, tricking it out with more than a dozen hidden cameras and then calling in the fix-it guys to see what would happen. But before they arrived, we brought in Steve Siara with RC Electric to inspect the system and create an easy-to-fix problem. Watch what happened next. #InsideEdition
