(a) A MANUFACTURED BUILDING (MODULAR) is a building of closed construction and which is made or assembled in manufacturing facilities on or off the building site for installation, or assembly and installation on the building site, other than mobile homes or recreational vehicles (NEC 545-3). It may be used for residential, commercial, industrial or educational purposes. A manufactured building is not permanently mounted on a chassis. (See § 1325.05 of this article and NEC 550 for mobile home rules.)
(1) Similar construction methods make it difficult to determine whether a structure requiring service is a “mobile home” or a “manufactured building.” To classify the structure as a “manufactured building”, the following condition shall all be met:
(a) Two-inch by four-inch by six-inch wall construction;
(b) Wooden floor joists;
(c) Trussed roof, with shingles; and
(d) Running gear designed to be removed by normal means and returned to manufacturer.
(2) A manufactured home is considered a permanent dwelling when it meets all of the following conditions:
(a) It is located on property that would normally be sold with the home;
(b) It is supported on a permanent foundation; and
(c) Water and sewage facilities are installed.
(b) Wiring in a manufactured home shall have a minimum 100-ampere service entrance (NEC 545-5 and 230-42) and meet all the requirements of Section 5.
(1) Metal framing shall be solidly grounded to grounding (green) conductor or grounding system (not the grounded (white) conductor.)
(2) A non-site inspection of service entrance conductors, metering equipment, service equipment and ground shall be made by company personnel and/or a local inspector.
(c) The service equipment shall be located at a readily accessible point nearest the point of entrance of the service conductors either inside or outside of the building (NEC 545-7).
(d) (1) For a permanently located home, service will be extended by either underground service lateral or when adequate mechanical support can be assured, by overhead service drop.
(2) It shall be the customer’s responsibility to provide adequate support for the company service drop conductors, provide and route the service entrance conductors from the service equipment to the point of attachment of the service drop and provide and route the grounding electrode conductor from the service equipment to the point of attachment to the grounding electrode(s).
