    Hint: Is that an approved bonding jumper?
    Aug. 20, 2009

    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.

    Find the Answer

    The Code allows you to install an equipment-bonding jumper inside or outside of a raceway or enclosure [250.102(E)]. If installed on the outside of the raceway, its length cannot exceed 6 ft, and you must route it with the raceway or enclosure. Although the length of this jumper does not exceed 6 ft, this piece of strapping iron (normally used for mechanical-type purposes) is no substitute for a properly sized conductor.
