<br />(b) Occupancy. Each occupant shall have ready access to all overcurrent devices protecting the conductors <br />supplying that occupancy. Where electric service and electrical maintenance are provided by the building <br />management and where these are under continuous building management supervision, the service overcurrent <br />devices and feeder overcurrent devices supplying more than one occupancy shall be pennitted to be accessible <br />to only authorized management personnel in the following: <br /> <br />1. In multiple occupancy buildings <br /> <br />2. For guest rooms of hotels and motels that are intended for transient occupancy <br /> <br />(c) Not Exposed to Physical Damage. Overcurrent devices shall be located where they will not be exposed to <br />physical damage. <br /> <br />FPN: See Section 110-11, Deteriorating Agents, <br /> <br />(d) Not in Vicinity of Easily Ignitible Material. Overcurrent devices shall not be located in the vicinity of <br />easily ignitible material, such as in clothes closets. !~~ <br /> <br />(e) Not Located in Bathrooms. In dwelling units and guest rooms of hotels and motels, overcurrent devices, <br />other than supplementary overcurrent protection, shall not be located in bathrooms as defined in Article 100. <br /> <br />. .

Grounding Electrode System and Grounding Electrode Conductor <br /> <br />. 250-50. Grounding Electrode System <br /> <br />If available on the premises at each building or structure served, each item (a) through (d), and any made <br />electrodes in accordance with Sections 250-52( c) and (d), shall be bonded together to form the grounding <br />electrode system. The bondingjumper(s) shall be installed in accordance with Sections 250-64(a), (b), and (e), <br />shall be sized in accordance with Section 250-66, and shall be connected in the manner specified in Section <br />250- 70. <br /> <br />An wlspliced grounding electrode conductor shall be pennitted to be run to any convenient grounding electrode <br />available in the grounding electrode system or to one or more grounding electrode(s) individually. It shall be <br />sized for the largest grounding electrode conductor required among all the electrodes connected to it. <br />rC..'..m. -n.. h~..",. <br />rr"""Y.""~ <br /> <br />The grounding electrode conductor shall be unspliced or spliced by means of irreversible compression-type <br />connectors listed for the purpose or by the exothermic welding process. <br /> <br />Interior metal water piping located more than 5 ft (1.52 m) from the point of entrance to the building shall not <br />be used as a part of the grounding electrode system or as a conductor to interconnect electrodes that are part of <br />the grounding electrode system. <br /> <br />Exception: In industrial and commercial buildings where conditions of maintenance and supervision ensure <br />that only qualified persons will service the installation and the entire length of the interior metal water pipe that <br />is being usedfior the conductor is exposed '.-. ._~. -.~.-. ="". =-1,. <br />.
