(a) Accessibility. Overcurrent devices shall be readily accessible unless one of the following applies.. .. ~ .:fc~~1 1. Forbusways, as provided in Section 364-12. 2. For supplementary overcurrent protection, as described in Section 240-10. 3. For overcurrent devices, as described in Sections 225-40 and 230-92. 4. For overcurrent devices adjacent to utilization equipment that they supply, access shall be permitted to be by portable means. [\C_t.wl (b) Occupancy. Each occupant shall have ready access to all overcurrent devices protecting the conductors supplying that occupancy. Where electric service and electrical maintenance are provided by the building management and where these are under continuous building management supervision, the service overcurrent devices and feeder overcurrent devices supplying more than one occupancy shall be permitted to be accessible to only authorized management personnel in the following: 1. In multiple occupancy buildings 2. For guest rooms of hotels and motels that are intended for transient occupancy (c) Not Exposed to Physical Damage. Overcurrent devices shall be located where they will not be exposed to physical damage. FPN: See Section 110-11, Deteriorating Agents. (d) Not in Vicinity of Easily Ignitible Material. Overcurrent devices shall not be located in the vicinity of easily ignitible material, such as in clothes closets. ifi::-~~d (e) Not Located in Bathrooms. In dwelling units and guest rooms of hotels and motels, overcurrent devices, other than supplementary overcurrent protection, shall not be located in bathrooms as defined in Article 100. . 250-50. Grounding Electrode System If available on the premises at each building or structure served, each item (a) through (d), and any made electrodes in accordance with Sections 250-52(c) and (d), shall be bonded together to form the grounding electrode system. The bondingjumper(s) shall be installed in accordance with Sections 250-64(a), (b), and (e), shall be sized in accordance with Section 250-66, and shall be connected in the manner specified in Section 250-70. An unspliced grounding electrode conductor shall be permitted to be run to any convenient grounding electrode available in the grounding electrode system or to one or more grounding electrode(s) individually. It shall be sized for the largest grounding electrode conductor required among all the electrodes connected to it. 'It.........tifll The grounding electrode conductor shall be unspliced or spliced by means of irreversible compression-type connectors listed for the purpose or by the exothermic welding process. Interior metal water piping located more than 5 ft (1.52 m) from the point of entrance to the building shall not be used as a part of the grounding electrode system or as a conductor to interconnect electrodes that are part of the grounding electrode system.
