How well do you know the Code? Think you can spot violations the original installer either ignored or couldn't identify? Here's your chance to moonlight as an electrical inspector and second-guess someone else's work from the safety of your living room or office. Joe Tedesco, who has a knack for finding shoddy electrical work, did the dirty work and found this mess. Now it's your turn to identify the violation.
Donald W. Zipse, a well-known forensic engineer and engineering consultant to the electrical industry, sent in this photo that was taken inside a cottage basement out on Cape Cod, Mass. “The two ground rods had a resistance reading of approximately 600 ohms,” said Zipse. “One rod revealed a reading of 900 ohms! I could not get around the other rod to take a measurement, however, calculations for the second rod resulted in a 1800 ohm value.”
There are two things wrong with this installation.
This installation is also a tripping hazard!
