Many of the changes to the National Electrical Code that occur during the revision cycle are pretty mundane and not too significant. Often the change in a rule is an edit for clarity or a terminology change, and sometimes an existing rule is relocated from one section of the Code to another. Regardless of the type, these changes often highlight the significance and implications of that rule. Such is the case of a rule relocated to Article 555–Marinas, Boatyards, Floating Buildings, Docking Facilities, which requires the bonding of all noncurrent-carrying metal parts that are in contact with the water [555.13].
