A device that provides a means for connecting bonding conductors for communication systems and other systems such as metallic gas piping systems to the grounding electrode (REASON FOR CHANGE: To allow fora a termination point for other bonding conductors in addition to  system.  communication systems that are required by the various model codes.) ***Article 110.2; change the following to read as follows:  110.2 Approval. The conductors and equipment required or permitted by this Code shall be acceptable only if approved. Approval of equipment may be evident by listing and labeling of equipment bya Nationally Recognized Testing Lab (NRTL)with a certification mark of that laboratory or a qualified third Exception: Unlisted eguipment that is relocated to another location within a jurisdiction ori is field modified is subject to the approval by the AHJ. This approval may be bya field evaluation bya NRTL or qualified Manufacturer's self-certfication of any equipment shall not be used as a basis for approval by the AHJ. Informational Note: See 90.7, Examination of Equipment for Safety, and 110.3, Examination, Identification, Installation, and Use of Equipment.
