Exception No. 2: Service equipment shall be permitted to be installed in or on a manufactured home, provided that all of the following conditions are met: a. The service equipment is completely installed by the manufacturer of the structure. b. The installation of the service equipment complies with Article 230. C. Means are provided for the connection of a grounding electrode conductor to the service equipment and routing it outside the structure. (b) Rating. Mobile home service equipment shall be rated at not less than 100 amperes, and provision shall be made for connecting a mobile home feeder assembly by a permanent wiring method. Power outlets used ARTICLE 550 - MOBILE HOMES AND MOBILE HOME PARKS 70-603 as mobile home service equipment shall also be permitted to contain receptacles rated up to 50 amperes with appropriate overcurrent protection. Fifty-ampere receptacles shall conform to the configuration shown in Figure 550-5(c). (FPN): Complete details on the 50-ampere attachment plug cap configuration can be found in American National Standard Dimensions of Caps, Plugs and Receptacles, ANSI C73.17-1972. (c) Additional Outside Electrical Equipment. Mobile home service equipment shall also contain a means for connecting a mobile home accessory building or structure or additional electrical equipment located outside a mobile home by a fixed wiring method. (d) Additional Receptacles. Additional receptacles shall be permitted for connection of electrical equipment located outside the mobile home, and all such 125-volt, single-phase, 15- and 20-ampere receptacles shall be protected by a listed ground-fault circuit-interrupter protection. (e) Mounting Height. Outdoor mobile home disconnecting means shall be installed so the bottom of the enclosure containing the disconnecting means is not less than 2 feet (610 mm) above finished grade or working platform. The disconnecting means shall be so installed that the center of the grip of the operating handle, when in its highest position, will not be more than 6½ feet (1.98 m) above the finished grade or working platform. (f) Grounded. Each mobile home service equipment shall be grounded in accordance with Article 250 for service equipment. (g) Marking. Where a 125/250-volt receptacle is used in mobile home service equipment, the service equipment shall be marked as follows: "Turn disconnecting switch or circuit breaker off before inserting or removing plug. Plug must be fully inserted or removed." The marking shall be located on the service equipment adjacent to the receptacle outlet. 550-24. Feeder. (a) Feeder Conductors. Mobile home feeder conductors shall consist of either a listed cord, factory-installed in accordance with Section 550-5(b), or a permanently installed feeder consisting of four, insulated, color-coded conductors that shall be identified by the factory or field marking of the conductors in compliance with Section 310-12. Equipment grounding conductors shall not be identified by stripping the insulation. Exception: A mobile home feeder located between service equipment and a mobile home disconnecting means as covered in Section 550-23(a), Exception No. 1 shall be permitted to omit the equipment grounding conductor where the grounded circuit conductor is grounded at the disconnecting means as permitted in Section 250-24(a). (b) Adequate Feeder Capacity. Mobile home lot feeder circuit conductors shall have adequate capacity for the loads supplied and shall be rated at not less than 100 amperes at 120/240 volts. 70-604 NATIONAL ELECTRICAL CODE
